The aultornator is charging at intermediate voltage and is very inconsistent, at times the aultornator won't charge at all then I leave the car for a couple days and it starts up and charges fine for a while and then it will stop charging I have had the rebuilt twice aultornator twice, not sure if it's not the ecm or something? This all started when my service battery charging system message came up and I seen that the voltage was low so I had battery checked, replaced the aultornator, still didn't fix it so I got a new battery and replaced the alternator
again, still hasn't fixed it! Now I have a brand new alternator and don't want to fry it?
