Sounds like you have a couple problems here.,. without enough detail to pigtail either one fully, I'm going to give it my best shot at a guess or two...

How much cranking is required to start the vehicle? if it is a lot - you may want to look at the fuel supply.. filter, the fuel itself and or the fuel pump.

Second: you have something draining electricity from the battery. is there a light inside the trunk or in the glove box where the switch may be stuck on even though it's in theory supposed to be off because the door is closed? -I'm thinking something is milking power from the battery without your knowledge? perhaps the cigarette lighter or something plugged into it? it could be something as small as a check engine light lit up would drain the power out...

Finally, dieletric grease to help with your electrical connections wouldn't hurt albeit most likely not a sole cause of the problem you are experiencing..

Best regards
Ck

Daughter called me ..car wont start. checked battery at Autozone...it is good. someone stopped to help them and bang on startere and it starts up. Bad starter. Starter replaced. Next day daughter...


it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

Car wont turn over tried charging the battery still wont start


clean your battery terminals very good!!!!! also make sure your battery has proper voltage...should be over 12 by a bit... maybe starter is frozen too hit the starter with a pipe or something similar as someone holds the key in start position.. if the car sat for a long time this is very common..

Car will not turn over and start. Battery is good. All eletrical function work. car was working great when we shut it off the night before.


If it still doen't turn over with a jump start, it's your starter.

If it takes a jump, and then dies out again soon after, it's your alternator.

I bought a new alternator for my 1990 oldsmobile and my car was running fine. A couple of months later i was coming home from work and my car had a hard time starting so when i got home i shut the car off...


You need to check if your alternator is charging. Buy a cheap volt meter from Harbor Freight for $3.
The battery should normally have about 12.3 volts.
When you crank the starter, it should drop down to about 10 volts. Once it starts, by jumping, it should go above 12.3, and as high as 13.5 when you rev the engine. If it never goes over 12.3, the batter will never get charges, and will eventually run down. But the alternator should have an automatic 12 month warranty. Take it back to them. And yes, running the windshield wipers will draw more current.

1983 Oldsmobile Delta 88 Electrical problem. I AM STUMPED


It goes thru the dash circuits. Yes! add a wire from the alternator output to the plus battery . The charge lite may be inoperative - either on or off. You might want to put a fuse in that new line.
A cheap volt-ohm-meter would help you see if the alternator is charging 14-14.8 volt and the alterantor field is being energized.
