when truck is running and you stop the voltage drops down very low. start up again and it picks up again to normal. when you first start it, it's ok but when it warms up it drops when you stop. i have replaced cables, cleaned ground, tested voltage at battery ok when you speed it up.what else should i check? the alternator looks new, i think it's beck arnely or something like that. otherwise the truck runs fine.
