I know you probably get flooded with these questions all the time and I
am sorry, but I am having a problem with my 91 Chevy Cavalier. I use to
have battery power (headlights, dash lights, everything else) but when
I attempted to start the car everything went dead. After about an hour
I regained full battery power, I attempted to start it again with the
same results. My ground from my battery was pretty rusty so I replaced
it, and checked all of my other visible wiring and did not find
anything out of the ordinary. I had a problem when my alternator and a
badly damaged wire about 2 months ago and installed a new alternator
and replaced the bad wiring. Thank you in advance.
Clean the battery posts. Clean the battery cables at both ends.
Get the car started, rev to about 1500 rpm or so, you should measure
around 14v across the battery terminals.
If the alternator is putting out and there is no excessive draw on
the battery when the engine is off, then it's the battery.
Of course, you could just have it tested.
