Im having problems starting the car up. I have changed almost everything and its still giving me problems. I always have to jump start the car. And sometimes that doesnt work. Today we had to push start it down the block. I just installed a new ground cable for the battery. I took my car to a mechanic this morning. They fully charged my battery and started the car. Another thing is my car will start when the battery is full but then it will die out quickly. He tested my alternator and said its good. !??! For some reason the battery dies quickly but will always have enough juice to keep the lights, radio, and other accessories on. !?!?!?!? My battery is only 1 week old and its already dead...

I have installed:
140amp alternator (1 week old)
new battery (1 weeks old)
new battery cables (2 days old)
starter (1 month old)
solenoid (1 week old)

Mechanic said I should change my battery. He said I should get a 900 CA. I dont know if that will solve the problem since I know my friend has a 88 lx with a 700 Cranking amps battery. He said if that doesnt solve the problem I should change my starter. My starter is less than a month old but watever. Like i said for some reason my battery dies quickly. Im getting frustrated with this. Any help appreciated. Thanks.

remove the starter and have it tested they will test it free at autozone. i agree with the mechanic the starter solenoid may and probably has a short. i had the same exact problem on one of my cars took me a while to figure it out but the starter and solenoid was bad. the starter is east to remove 2 bolts and 2 wires...

Just to clear confusion, Bill's thinking of the SN95 starter solenoid - on a fox it has a zillion cables on the solenoid's battery lug.
When it wont start, do the headlights come and stay on strong? If not, there's another issue.

It would not be the first time someone got a bad battery brand new. I'd want to also compare voltage at the back of the alternator vs battery voltage while the car is idling and at 2K RPM. If the fusible link for the alternator burned, the alt can bench test fine but you're not charging the battery.

Use of the DMM will help a lot.
Good luck.

Headlights do stay on strong when the car isnt off. Ill check the voltage for the alternator and the battery. Thanks hissin50.
