Jeff, that is a symptom.
now that you have owned it for about a month?? here is my recommendation for all owners:
make sure you at least have one of these:
http://bdub.net/gmcmotorhome.info/APC.html
take a look at the wires coming out of your alternator. see if one is installed, and if not- order one up today.
next for spares and things that I think at a minimum need to be carried in the coach at all times(this is my personal minumum list- the full list
probably has no end-) When people call up and have issues, there is some basic problems that can be quickly troubleshooted, or fixed, before you
have to really start thinking on the problems.
1. VOM meter - with your alternator light situation, I would want to know what the voltage is running/not running. and at each post of the
isolator, with coach not plugged in. usually when the light is dim, getting the alternator rebuilt or the isolator is bad. but a VOM meter will
let you diagnose before spending money.
2. Schrader valve - 2 of these for sure, to keep for emergency for yourself or others. small and cheap.
3. isolator vavles on the air bags- so many leaky and problematic air systems out there. this will keep you up if there is ever some problem.
Schraders are guaranteed to work, but valves are quick.
4. ignition module- 4 out of 5 GMC engines that stop running, a ignition module will get you back moving until you can buy a new coil.
5. timing light. - not for checking timing- but easy to check for spark. then you can figure out where to go from there.
6. fuel filters and 1" and 5/8" wrench.- if your having running problems, start with known good fuel filters, then you can troubleshoot from
there.
7. I keep a 24" 12awg jumper wire with good alligator clips handy. helps with testing with VOM meter, and you can jumper the onan, the boost
solenoid, and a few other things in a pinch.
that is my minimum list.
