I will get the best in put from you guys.
My dad's 95 king cab 4wd d21 has electrical problem. It started with what we thought was the alternator going bad it got tested, it was in GOOD working order. The battery was tested next, same answer GOOD working order. The starter was tested next , same answer.
This truck had one pr-existing problem the electric speed-o-meter stopped working. Could this be the source of this problem and possibly other mystery shorts in this truck????????
