Cavalier Trouble

Hello, could some one please give me some advice?

I have a 1990 cavalier. When I go over a small bump my electric light comes
on for a split second and I lose power in the engine. When I go over a
larger bump, the same happens for longer and my stereo turns off.

Ive checked most electrical connectors in the engine bay and cant find
anything lose.

Does anyone have any idea where I should start a more detailed search??

Many thanks

John

 

More info on the engine, its a 1.6 SV engine with the ECO carb, if that
helps at all.

Hi
Worth a check - on some Cavs. the earth strap on the alternator (if not
modified) is a fairly rigid cable. The alternator is mounted on rubber
mounts and flexes with load / bumps etc. The next thing that usually
happens is that all things electrical start behaving unusually - radio turns
off & electric antenna collapses, various lights come on on the dash etc.
Fix: - change the earthing strap for a proper battery earthing strap - job
fixed for the life of the car!
It happened to me along the A1 in the early hours of the morning, once.
Hope that helps
Rob

 

Thanks Robert. Come to mention it, it might have started after I had to
change the rubber mount for the
adjustable alternator support arm, where the earth strap is!!

Many thanks
