Charging voltage

Postby Crackpot » Wed Apr 30, 2008 7:03 pm

So what should I be reading at the battery if the alternator is charging correctly.

My meter shows 14.90v while running and 12.6 while off. Should I measure amps instead??

Just wondering, redid the voltage regulator harness today after my battery went dead yesterday.

Amps can be checked, but w/o draw, the amps are not going to be there! Best check (easy one) I know of is at an idle, headlights on, blower fan on, interior lights on and flashers on... as the flashers pulse there may be slight variation, but it should stay pretty consistent for several minutes (voltage at battery that is). If there is some drop, bump the throttle and see if the voltage climbs accordingly.

Best of luck...and Happy Motoring- Zeek
