What size alternator would my truck have come with stock? i ran a battery, alternator, and starter test on my truck today with a VAT-45 and I toppped out at 135 Amps while charging. My Starter pulls 129 Amps cranking for 15 secs too

Probably a 140 eh?

And my battery all the cells were about 1.500, only one was a 1.225, well in spec, good for a battery that came with the truck when I bought it

 

Nominal output is 130, but actual output will vary widely with age, temperature, battery voltage, loads...
