I can relate two stories on how electrical ground faults can
drive you to drink even if you do not currently drink:
- 1990 Chevy truck. Cranks and
runs great. Hit something like a fan switch or radio button, car acts as
if any thing electrical on the vehicle disappered for a second to the
point where the dash board would do its power up light test and the engine
would restart because it was a manual going down the road. The guy I sold
the truck to gave up and the guy after him figured it out. I should have
figured it out as I had many times seen the problem but did not understand
what I was seeing. The ground cable at the battery end has a smaller wire
running off of on side going “somewhere.” Turn out that is
the ground for things other than the starte, it was very intermittent and
all of the problems went away once the cable was replaced.

Yanmar tractor. Good charge on
battery. Go to start it and I would hear a pop and then it was if the battery was
not there. Removed cables from battery and cleaned everything and reinstalled
good and tight. Same results. Sent off for starter switch. Same results.
Finally noticed that the ground and positive battery post connectors were the
clamp on kind with bolts. I removed the ground side and it was corroded and
dull. Bought a new cable end and problem went away. Have had this same problem
on the positive side if the cable were not tight as a lot of pressure is placed
on the connection when trying to crank the motor.
