Hey guys.

So I had some issues with the car today. In traffic all of a sudden the I lost radio and CD player and the car was in limp mode. Break-up under boost, 4wABS and Charge battery light on. Later at a stop light, EXTREME break up at take-off and after about 10 seconds it started driving again.

Silly me decided to pull off and shut her down. Wouldn't start again. Just clicking. Got a jump and made it home. Shut her down and wouldn't start again. The battery holds charge until I drive the car so I suspect the Alternator.

1. Am I correct in this assumption?

2. My buddy has a spare Cosmo 20b alternator. Can I use it on my car?

As always, thanks for the info guys!

 

take it to autozone and have em test alt?

 

Thats a start. Looking for info on if I can use the Cosmo Alt now. *bump*

 

if you have a digital multimeter you can test the output of the alternator.

 

Well I've never held them side by side, but they look identical from what I remember.. I'd say the the odds are good that there the same alternator.

 

Could be the alternator or battery.

Test the alternator with a volt meter (when running) and see if you can get about 14 volts. If so, test/replace battery. If not, replace alternator.

 

I can't comment on the Cosmo alternator (I would assume it's the same), but it sounds like you have an alternator problem, not a battery problem. I had the same thing happen to me, I replaced the battery but it didn't help. I got the alternator rebuilt; now it works like a charm.
