I was fortunate enough again to have GMCMI fall rally just 3 hours away, so I sneak away from 4 days of being at work and was able to attend for the
week. I used to really enjoy Dan Gregg's photos and commentary on the conventions, and I have taken better photos in the past. This year many
friends that attended had some nice photos of the happenings on facebook, but most here probably did not see any of them, so I posted a few over at my
blogsite, so others can enjoy.

I think this is the 3rd full GMCMI Rally I have been able to really attend, and the 2nd time my coach had been able to be at one(both at chippewa
falls) I did do a day trip to one in my early GMC ownership years when Dan insisted I at least show up to see what it is about.

We missed many who did not attend. I think they had about 85 coaches, and I heard over 100 registrants. I heard 29 1st time attendees, and I know
many of those are very recent GMC owners. I did not hear any of those claim that it was a waste of time, and at least 2 were bummed that they could
not attend the entire time.

Pretty cool things to see and do. they were installing windshields Saturday from 8am till Midnight and again back at it from 8am until at least 3pm
on Sunday. Walt's coach was constantly circling the fairgrounds as he had everyone testing his brakes. He may need new pads when he gets home from
all the stops! He even did a breaking contest against wally one morning(wally's coach did stop quicker). Coaches were weighed, headlights alined.
I swapped out an owners airbags. One water pump was swapped out last weekend, but I think there was not too many major repairs. One guy brought
his coach in on a gooseneck trailer on purpose. there was a oversized GMC mounted on a class A chassis to check out. Plenty of food, good
information shared.

Also a shout out to Sirum GMC for having a small crew on hand with parts to buy without paying shipping. They even installed a couple items for
people, but more importantly sharing knowledge and helping guide many of the 29 new GMC owners on some proper repairs and what to watch out for to
keep their coaches off the back of a tow truck. other venders such as JimK, JimB, DaveL, and others took time for virtual presence and answered
questions for attendees as well.

so here are a few photos for those that could not make it, and a reminder of the fun for those that did:

Thanks Jon,

I have been missing Dan's commentary on the GMCMIs too. It's great to have some pictures to at least see what was happening.

We hope to make it to more of these now that we are retired, just couldn't make this one.

We actually ended up with 34 first timers, and several wannabes.

Enjoyed the pictures Jon

yes, we have lots many mentors and GMC people in the past 10 years I have owned my Coach. Dan Gregg was one of them. He was a big ambassador for
GMCMI and the conventions. I had the honor of meeting him at a VW show in Effingham and he is the one who convinced me to attend a GMCMI convention
even without my coach. In those days I could not afford the gas, time, and my GMC probably was not up to going past the 200 mile AAA tow rating at
those days.

He also has contributed to some great information on GMC travel that hopefully will live on forever.

He took many photos of the GMCMI events back when he was around that allowed us who could not travel so far to feel like we were almost there:

http://www.gmcmhphotos.com/photos/m340-dangregg.html

He also had a wonderful blog that motivated many to get out and enjoy their GMC rather then letting it sit and rot in the driveway:

go read his blog over to learn about how to stay comfortable traveling for months in your GMC.

Thank you for the highlights, Jon.

Bob and I wished to be there, but we aren't doing much traveling these
days. Some of our fondest memories are of GMCMI Conventions and the
wonderful GMCers from different parts of the world.

Good to hear about so many first timers. They are who will keep the GMCs
out on the road. Use and enjoy those coaches!

Sandra Price,
I don't know you. How annoying is that!
But I likely would have met you and had a conversation at the convention.
We toured Texas, a great circle route, just before COVID hit and followed the advice of several forum members.
We had a memorable week staying with Steve and Mary Allyn Hendricks who were amazing hosts and had a wonderful time in Texas.
Hope we meet sometime.

Thanks, Douglas.

We always like to get to know other GMCers. Sorry we haven't met.

Have seen some of your exchanges on the forum. Keep enjoying the rv life!

Yes, it was almost an international and it didn't lack for Kim's attention at all.

With only about 80 coaches and about 130 people, it was smaller than many but did not lack. What was grand was the 30% first timers. That meant that
there were a lot of new faces to meet.

But, you know, without none of our Canadian friends, either of the Kens, no Emery and JimK only on the screen, it was just lacking something. We
still are glad we went. This may have been the first time we didn't win anything, but that just not important. We went through Chicago in the
morning traffic and it was still bad, but we mad it.

About 20 minutes ago, we crossed into Indiana on I-94. We are pointed toward home. We have a planned stop in Portage Michigan to buy fuel at the
Sam's club there, and then it is run for the barn time.

Yes it was a different kind of rally, with the absence of the Canadians, Dave & Mary L (but they did make an appearance via internet), Ken H., Emery,
Ken & Janet, Ken & Laurie etc. But it didn't disappoint. The tour, dinner and show at the historic Mabel Tainter Center that Larry & Lucy arranged
was very interesting and fun.

I stayed an extra day in order to revisit (from 7 years ago) the Irvine park/zoo, Jacob Leinenkugel brewery and the Chippewa Falls Museum of Industry
and Technology. I was the only visitor and had a really nice tour of that facility. For a small town in the middle of Wisconsin, Chippewa Falls has
a lot to offer. I still marvel at Seymour Cray's super computers doubling as furniture.

On the way back I ran into Sonya & Terry N. in a rest area on US2 not far from St. Ignace. We spent a few minutes discussing how to improve the look
of my '76PB. Their PB really looks nice.

I'm not quite home yet as I spending a few days to winterize and otherwise get ready for winter our place near Mackinaw City.

I posted this on the other forum, but many that are here aren't there. Good news coming from a GMCMI convention ought to be welcomed.

I apologize for this long post, but this seems to be a good place to convince skeptics that GMCMI conventions offer great and sometime unexpected
delights. This was the second GMCMI convention we've attended. The first we arrived late because of cooling problems with the coach (solved by help
from an attendee). This time we were there for the whole thing and had a fine time. The reason you go though is to learn things.

First example:
In the GMC 101 Session a guy held up his fusible link and said "this looks great, doesn't it?' He then bent it and said "but there's nothing inside,
the wire burnt up on the way to this convention." He then proceeded to tell us where the fusible link starts and ends. (It starts at "battery
positive" and ends at the horn relay) That fusible link feeds most everything on the dash and other important stuff. I have owned my coach for 25 yeas
and have heard fusible link stories for 24 but I've never had a problem with it so I never really learned where it was. 20 minutes later I'm looking
in my right (passenger) access panel at my fusible link and knowing for the first time in 25 years what it was. Jeff Serum said to go out and buy a
12V 30A breaker to replace the wire and fire will not be an option. Sweet.

Second example:
In the same GMC 101 question and answer session Larry Weidner says "You really should have someone else drive your coach from time to time. Some
problems are very slow onset and you don't recognize them but someone who has driven their own coach may recognize it right off the bat." So I asked
him to drive mine.

More information came from that test drive that I could possibly have imagined. 6 wheel disk brakes that I installed, Check. He liked the way the
coach stopped. Steering and front end, Check. He said it tracks and steers very well with little or no slop. Floored it in 3rd gear up a hill...
Uh-Oh... No transmission kickdown, no change in power, lots of pre-ignition (Ping), and no secondary opening of the Quadrajet. So, the timing is
screwed up (I did that just before the convention.[SH!T]. There is a vacuum issue or faulty kickdown switch on the accelerator. My Quadrajet
installation has to be inspected and monitored at speed and problems corrected. Larry said my coach runs really well if it is driven easily and the
secondaries are not invoked, but that the ignition advance could damage things and each of these things should be corrected ASAP.

The power thing I had wondered about, the transmission thing I didn't care about because I don't drive the coach that hard (fast but not hard). But
the timing thing, that was a revelation. At light throttle the coach is fabulous, scoots up hills, tries to get me to 75mph when I don't want to, gets
(for a GMC) good mileage so I had little motivation to change things. But Larry has more experience with coaches, has better hearing than (old fart)
me, is a terrific mechanic and knew the damage potential if things were left untouched.

I could end here and say I learned a lot, but wait there's more.
Chatting with Wally Anderson (40 miles from me, but we'd never met) he offered to help diagnose and solve the problems. Win, Win and Win. Good things
confirmed by a knowledgeable driver, bad things diagnosed and a splendid mechanic found to help fix them.
THATS why you go to GMCMI conventions.

Campfires, banquets, breakfasts, coach tours-- you may or may not like the social stuff, but the diet of information and good-will trumps any
reluctance to dance in front of strangers. Oh, and I got a new drivers-side windshield installed by someone who's done GMC's for over a decade. They
are really good.
So, sorry no pictures. Just a random story from someone who's really glad he went.

I am a terrible typist and this is my third time trying to post this.B

I disagree with whomever made recommendations in Item One and the transmission down shift switch.

Item one. Replacing a fusible link with a 30 amp CB is a BAD idea. A CB is a designed to shut off voltage immediately when it see an over current.
Almost everything thing in your coach already CB or fuse protected in their individual circuits. A fusible is there to protect wring etc. from gross
overloads. As such it is a time delayed last chance interrupter of voltage to the WHOLE 12 volt (engine side) Of the coach which I guaranty is a
whole lot more than 30amps. Think of a few higher current things you could be running concurrently. I believe the suspension compressor is CBed or
fused at 30 amps. How about the head,tail, clearance brake, and turn signals lights? Add to that the radio and Cruise and you can see how it. Add a
few of these together and you can see why 30 amp is not going to hack it.

The fusible link is a special wire designed Specifically NOT to cause an electrical fire. You can get a replacement at most auto parts stores for
around $3.00. I believe our fusible link is 16 gauge black.

Stolen from the internet.....

"This low-voltage, insulated automotive cable is designed for use in demanding automotive wire harness applications where standard fuses are
unsuitable. The fusible link protects the automotive cable harness in case of extreme current overload. If this occurs, the conductor within the link
melts while its insulation contains any spark or flame emitted, preventing potential electrical fires.

So if yours is bad, just replace it. That should be good for another 40 years.

On the transmission downshift. This is usually the rod the gas petal is mounted on is bent downward a bit and the switch on the other end of the rod
s not being transferred. Pull up on the pedal end bend it towards you . Then look at the switch while pressing all the way down on the pedal to see
if it transfers now.

I was just about to comment on the fusible link topic, but Ken B covered it very well.
I don’t have the schematic in front of me but from memory is that add on breaker were to open, charge Voltage would overshoot high, That could cause
secondary damage.
There was pretty much a “reason why” behind everything engineers did. Only understanding part of the picture and not the whole scope leads to
problems when people try to improve on designs.

I might be mistaken, but I think our GMC only has the 1 fusable link? it is not located in the harness, but on the firewall between the battery
post and a relay?

here is the part number for the replacement:

The Fusible Link IS outside of the wiring harness and I've never heard of
one doing damage. On the other hand, there is within the main cockpit
wiring harness a Nichrome wire used for excitation of the alternator's
field, which can, and HAS caused severe damage to the other wiring in that
harness. Gene Fisher's Alternator Protection Cable (APC) SHOULD be used to
prevent that possibility; it works by preventing high voltage from a
malfunctioning alternator from passing back through that 10.0 Ohm cable.

Thank you Kens, Jon and Emery.
I think I understand the fusible link much better as well as the alternator excite wire. I have an October 1973 coach and every single time I look under anyones passenger access panel I see something different and something different from what is under my own. Having never had a problem with my link, I didn’t even know which wire it was. I already have installed the Alternator Protection Cable so, in theory, I shouldn’t have a problem with my exciter cable either.

Ken, I will take your counsel that a fusible link is fundamentally different than a breaker and should not be replaced with one. Apparently Jeff Sirum has a different opinion.

Thank you all.
Doug
