So all a suddenly my idoit light for my alternator came on. I have a brand new alternator and batteries. But I took it off and got it tested, they said it was bad, so I put a extra old alternator on that was still good. But it still doesnt seem to be charging right. I think something with my wiring isnt right, its a m1008 that i converted to 12v, but I swear the wiring on this truck sucks. My question is, the alternator can be connected straight to the batteries right? Also the 2 prong wire is just for the idoit light right? I checked for shorts but didnt fine any, no wire seem to be getting hot.
