Inteli-Power 9260 Repair ?

[jerry burt]

My Progressive Dynamics PD9260CV is not putting out DC voltage. I did the trouble-shooting in the manual to confirm it. The unit was in the coach when
I ought it so I don't know how old it is. Regardless, online research indicates it is basically a non repairable unit. A replacement converter
(PD4560CSV) is available for $2.00 less than buying the whole unit.

Looking at the replacement converter photos and the wiring diagram, I don't see any replaceable parts. Does anyone have any experience repairing these
or is this one going to be just another anchor.

Thanks

You might drill out the rivets that hold the case together.
It might have gotten a voltage spike. This can sometimes burn a MOV.
The Metal Oxide Varistor or MOV is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. The Metal Oxide Varistor is designed to protect various types of electronic devices and semiconductor elements from switching and induced lightning surges. This component looks like a disc capacitor and it can sometimes burn up and be easily replaced.
It could also be some burnt capacitors.

Open the case and take a look.

Jerry,

Most have heard my tale of the Progressive Dynamics, but I'll repeat it
anyway: 10-12 years or so ago, my PD91xx (which I'd bought several years
before, refurbished) failed. I opened it, as Emery suggests, and found
that the output lugs had come unsoldered from the printed circuit board. I
resoldered them and, as a reinforcement, added screws through them. That
was the end of the problem, as far as I was concerned. But, I mentioned
the incident here and someone forwarded the tale to Progressive Dynamics.
Well, before I knew it, they were writing and calling me, repeatedly,
wanting me to return the PD91xx in exchange for a new one. I finally
agreed, and they not only sent me a new, later design (PD9240), but sent a
few "Charge Wizard" controllers for me to give away at GMC rallies.

That incident has been a large contributor to the popularity of PD ever
since. You CAN repair 'most anything -- and it sometimes works out better
than you expect.

Jerry,

I suggest that you look more closely at the PD catalog. The 45XX are power centers and the 92XX are stand alone converters. There may be packaging
issues. However, I am sure than if you contact the PD tech people, you will get good and honest answers. There is a reason that they are so
respected on this board.

Also, an XX60 from PD is a little large for a pair of GC2s. The reason I have one is that I had to move mine to a place next to the passengers right
ankle to get the wire run short enough to recover the house bank on the APU when at a music fest and I want to minimize the annoying run time. The
9260 is a flatter package than the 9245 by about an inch.

Thanks for the responses. Electronics is not my strong suit. I'll take it apart and "see" what I can see (I've got nothing to lose). I'll also contact
PD for more info and check out the 45XX.

Thanks again.

I've been in electronics for 40+ years, and used switching power supplies (as opposed to linear PS with the heavy transformers) almost exclusively for
the past 25yrs. Linear PS are heavy and run hot under load. Switching PS are light, relatively inexpensive, and run fairly cool even under heavy
loads. Linear PS are usually simple and easy to fix, the electronics are on the low voltage side. Switching power supplies have many electronic
components connected to the line on the high voltage side.

Usually its a surge (from nearby lightning etc) that takes out a switching PS. Fixing it can be tricky. Usually you can troubleshoot to a couple
faulty components. After replacing them you try to test it and BANG the magic smoke comes out of the new components. So more troubleshooting... a
variable auto-transformer helps reduce the amount of replaced components you blow up while testing.

So after several hours and a mitt full of blown parts you get it running again. You have to write-off a bunch of time and parts because the customer
doesn't want to pay anymore than half the price of a new one to fix the old. Then next day, or next week, or next month, it fails again. There is
always a high voltage part that was stressed and is going to fail in the future. You end up eating all the time and parts you put into it and sell
the customer a new one.

So lesson learned, is switching PS are cheap compared to fixing them. Buy a new one to replace it.

I wish I had read about Progressive Dynamics sooner. I ebayed 9270 last
June. About November I discovered the connection on my 15A cord had
overheated and 4 of 5 batteries were dead. I had not jumped the genset
starting battery to the house batteries like I did the chassis battery. I
unplugged the 9270 and plugged the coach back in. Almost no current draw.
I amazoned the next 9270 but have not installed it.

Well, I got the cover off and didn't see anywhere the smoke escaped from or any loose connections. Reading Bruce's post, I think I'll order a new one
from Amazon.

I may as well add the 2nd combiner to the charge system while I'm there.

Matt, the PD45XX would be nice if I had a wall with enough free space. As I'm configured now, it would not be practical.

Thanks again for your help.
