Dead battery

[festfull]

Thanks for the pics.

I'll try to pick up a few.

Tested and replaced the battery at the parts store this morning. It still had time left on the warranty.

Also picked up a set of fuses

Thanks.

Now wasn't that a lot better than trying to hunt down a non existent problem!
Remember diagnose.
Then repair or replace.
Enjoy your car now.
Bet it runs a little better too!

Yes,its but what is the Alt output ? If its 13.5 your new Battery is gonna end up like your old warrantied battery... You need 14.5-14.75 with your brite lights on heater fan on high.

Good point, but I would imagine he had the battery and ALT tested at the same time and the ALTs output was fine, but he had a dead cell per a load test.
So replaced the battery.
But lets let him tell us what was done!

The battery failed and the alternator passed.

The voltage I got from the alternator before the battery change was 13.2
That's low but I dint know if the bad battery had something to do with the reading. I didn't have time to test it again after the new battery was in. Will after work tonight.

If the battery is the problem it's was an easy fix.

Thanks for suggesting I look at the big picture. The battery is still newish and my mind wanted it to be something the AC shop messed with.

Thanks again

test your alt again, run the engine with the wipers, lights, radio, blower motor running on high. you should have NO LESS than 13.6 vdc at the battery with those conditions.

Thanks, will do.

Isn't the normal range something like 13.5 to 14.5?

[FestYboy]

yeah, but a properly working alt should be able to keep 13.6 or higher under normal loads.

[festfull]

Tested the alternator this morning. I was getting 12.6 across the terminals. That's with the car running light on high, radio and AC on. That's low if it's even working right?

Bad alt

[festfull]

So you think the alternator killed my last battery?

CAPS LOCK HERE FOR A REASON, CHANGE THE ALT BELT !!!!!!

When the belt wears it will let the alternator pully spin under load and look like the alt is bad when it is just the belt, sounds dumb but every year and a half or so my lights go dim and the belt looks good but I change it and it goes back to 14.4 under load.

It's probably glazing, not a bad belt. Take a still write brush to the belt ands pulleys, clean them up good. Then tighten your belt properly. Shouldn't be happening in a year and a half...
