I currently have the ground wire from my battery connected to a spare bolt hole in the front of the block. I have a ground strap going from the block to the fire wall. I am having trouble starting my truck when it is hot. It seems as though the starter is not getting enough power to the starter when hot. I was told by the person that installed my wiring harness that I should connect the battery ground to one of the starter motor bolts. I was looking at a tech article Classic Trucks magazine and it looks like they have the battery cable bolted to the frame with a ground strap going to the cab and at the starter motor they have a ground strap coming from the starter and going to the frame with another ground strap going to the cab.
Which one should I do?
