Westberg tach/vac

[gworobec]

After having the coach die on two occasions and changing out the coil and module in the HEI distributor with no avail I checked in with Dick Paterson. He suggested the tach wire to the HEI high might be the problem. Guess what, that is what it was. I did trace the wire back to the Westach tach/vac combo gauge that a bunch of us bought on a group buy a way while back. The wire was good. Looks like an internal failure in the gauge. I’m leaving the gauge in with the vacuum part and adding an Autometer 0-6000 rpm 2 3/4” inch gauge mounted on top of the horse collar.

Thank you so much Dick Paterson for always being there for us.

Gary,
You are very aware of the SYSTEM we have in our community. You have been a
presenter at one of our Western States Rally as well. Thank you.
The NEW owners must become aware of us and what we bring to the table.
I receive over 20 calls a day and manage to answer ALL.

Gary,
I had the same issue with the motor cutting out and running poorly back in 2009. I had an aftermarket tach mounted on the steering column.

A word on mounting your tach when you add one is to try and mount the tach with your run RPM in the 12 o’clock position so your needle is pointing straight up when your at cruising speed.

Was in Greenville, SC heading to FL and as we left the RV park is was running, missing and generally running poorly. I had remembered a post on the gmcnet that one member had had a similar issue and unplugged the tach. Sure enough, that cured the problem and that tach was in the junk.

For those of you that noticed:

I had added a voltmeter in the dash in the same location that the optional factory voltmeter was installed.

An O2 exhaust meter is just to the left of the dash.

The set of 3 gauges show the RT, LT airbag pressure and the center is system pressure.

The black box with the switch and light are a manual brake controller for the towed that allows to add brakes with out braking the coach.

Thanks J.R,

The Autometer 0-6000 will be great as the 2800-3000 rpm band that I run in will put the needle straight up.

That's not an unusual occurrence. My engine began to miss on a trip a few
months back. Since the tach had been a little erratic, I immediately
suspected it and disconnected it from the distributor. Engine hasn't
missed since. That was a several year old VDO, which I haven't yet
replaced. That's not the first one I've had trouble with, and John Beaver
tells me it's one of the first suspects when they have trouble with racing
engines.

Put your oscilloscope on the DC coming out of your alternator.

My erratic tach readings and blown modules were induced by an alternator that was sporadically making AC. Eric Tanner fought the same issue.

Dolph,

I might do that ('tho' I don't think it's the source of the problem -- I've
NEVER blown a module) if I hadn't given my 'scope to my grandsons. Next
time I have the coach there, I'll do it though.

I had a Westberg tac prior to getting my Mac dash and never had any problems with it. I then installed it into Walter Drew’s GMC. Walter lived in Santa Fe. I don’t remember who bought his GMC but it’s someone on this net.

Last summer I burned up 3 coils. I found that there was an intermittent short between the hot lead in the distributor and the tach lead.
After I replaced the wiring harness leading to the distributor it solved the problem.
