My dash lights came on (temp,battery and brake light). Garage said battery and alternator, replaced battery, took alternator to autozone they tested it several times and says it is working properly. What else should we check. It runs then those dash lights come on and eventually car looses power and quits. Any help would be appreciated.

 

Did you do a voltage test at the battery with the car running?

 

Yes and it showed good!

 

14, then down to 13.9

 

I'd check the wiring between the alternator and battery and the main ground connection to the chassis.

Might want to do a voltage drop test and ohm it out.

 

Thanks, we r actively working on a couple ideas, but running out of ideas quick!
