Thanks Rod I'll give Allied Recreation Group a try maybe they can shed some light on my installation.
Maybe others might have some insight on my dilemma. The problem I'm having is intermittent drive motor assy operation. Over the last few months the operation has been more and more sporadic. Some of the things I've done is disconnect the wiring at the motor and I measure 12.8 VDC, slide switch operation seems solid and consistent. With power to the motor I measure 10 amps when the motor does not start, after repeated tries of the slide switch it will finally start (sometimes) and I measure 3 amps while the motor is turning.
I've pretty much ruled out the drive assembly motor as my problem. I removed it from the coach and hooked it up to a battery and it ran every time I tried it, forward or reverse. I located the armature brake under the end cap and everything looked good every time I operated the motor on the bench, brake released and everything worked fine.
I reinstalled the motor assy in the coach without connecting the coupling to the shaft and it would not run. Ran a jumper out the window directly to the batteries and it ran every time again. For some reason the brake must not be releasing when I see the 10 amps, I just need to figure out why. The specs on the brake indicate it only requires about 0.6 amps to operate. The slide switch and motor wiring is 12 awg so that should be more than adequate for no more current than the motor is drawing when it operates, plus its worked fine the past 3 years.
I've about decided the problem lies with the coach batteries. They are 4 years old which I would normally think was not very old. I can't think of anything else to check, just wondering if anyone has run across a problem similar to this. I'm not anxious to run out and spend $500 - $600 on some batteries if that's not the problem.
Can the coach batteries be load tested while still installed or do they need to be removed and isolated to get an accurate check?
