Alright here's my first test.
I know the battery is a little low, going to put it on the charger but,
Battery reads 12.04 when it's off
jumps from 10.98 to 5.8 when it's running

Alternator reads 12.24 running on the big main lead
.26 on the little wire when off
and 10.98 running

 

easy enough i guess. the morons that tested the alternator didn't test it right.
sorry to bother you with this stupidity

 

FYI, Battery voltages for a Lead acid

12.70 fully charged
12.20 50% charge
12.00 25% charge

Charging voltage will vary depending on which cycle the battery is in. At 14.5 the battery is charging, once charged the system will float charge at about 13.5v.

These voltages will vary slightly depending on how accurate your meter is.

 

Good info Warren. I knew it is suppose to be above 12, just didn't remember what exactly.
Thanks
