Battery dies after jumper cables are removed

Asked by May 13, 2017 at 01:41 AM about the 1985 Chevrolet Celebrity Sedan

Question type: Maintenance & Repair

Hello i have a 1985 Chevrolet Celebrity with a 2.5
iron duke. This car has been giving me problems
since i replaced the alternator. The alternator does
charge however when it would sit for awhile it
would drain the battery. Now when i hook it up to
jumper cables it starts right up but when the
cables are removed it dies 2 minutes later and
theres no power going to anything. I looked for
broken or loose or corroded
connections....alternator is good....battery brand
new. Someone told me that the starter relay could
be bad and i was also wondering where it would
even be located. I checked the usual suspect items
and everything is fine. Any help with this is
appreciated. Thank you in advance.

Does the alt light turn on when the key is in the on positions? If not that has to work as it is part of the activator circuit for the alternator, you may also need to check the alternator wiring, especially on the car this old wiring can break down or out my way get what we call rodent damage.

I always wondered why it wouldnt come on when it would act up. It does when you first turn the key on but while driving when it had an issue it wouldnt.

Have you done a battery drain test? You will need a fully charged battery.
