i changed the alt and it has the same problem, ididnt check the second alt . put it was also checked on a machine at a shop. he said there is something in the truck cause it works with compuert?
that second alt was tested and it puts out on the machine and in the truck keeps going down as you drive. it sarts out good and later goes down and we have a new battery in also?
no its aplane two work tr just radio only noting more. but it has that wire connecter by battery and it looks good at the connecter. so this is power by the pcm right?
ok i would take time check it out thank you .get back later today maybe >
