I just had the second call for today from a stranded GMCer.
His first call described a failed ignition coil. Installing the new spare
he'd bought several years ago didn't help. He was awaiting receipt of a
replacement ignition module. He wanted to know if I could think of
anything else he should be suspecting. We both figured the shorted coil
had taken out the module, so I couldn't help.
The latest call informed me that the ignition module didn't help. But
re-installing the "failed ignition coil" DID! Turned out, the module WAS
the problem, but to confuse things, his long-depended-upon spare coil was
BAD!
The big lesson here is one we tend to forget: When buying a spare, ALWAYS
install it and let the known-good old item become the spare. Especially in
these days of dubious quality control, it's a very important precaution.

One more good reason to run them before "sparing" them. :-)

I like what Gene Fisher says " Run your best parts". In all of my years of
driving these coaches, I have needed a master cylinder, a mechanical fuel
pump, and belts. The rest I have discovered and fixed in my shop during
routine maintenance. Which is the best place to fix stuff? In the shop
where you have light, tools, heat, etc. or beside the road? Your
experiences may vary.
