I had a problem a few months ago with my 92. one day it starts the next
it doesn't, at first i tried messing with all the wires and it would
start half the time. I then started to replace all electical parts,
still did not fix it. one thing mine did do when it was running was
charging at 18 volts when it was running, (not a good thing) I broke
down and took it to the dealer and they said I had a brocken wire in the
harness. I guess this wire was totaly shutting down the computer and
everything still don't understand why it did it one day and not the next
though. anyway no problem with it since. Hope this helps
Dan
