on the alternator on the back theirs a nut that has 12 volts comming off it, when you start the car it jumps to 14 volts
does that mean the alternor is charging right?
More or less as long as it's putting out more running than it reads when it's off then it's charging. Big thing is if it's still putting out more when the accessories (fans stereos etc are all on)
