been having issues off and on for a couple months now and i know it's the starter not getting grounded well enough. we even ran a wire from one of the starter bolts to the frame and that helped some but every once in awhile it wont start but if you take that one starter bolt out and put it back in it usually fires up then. what can i do for a permanent fix?

 

Remove them and it and wire brush stuff to get rid of corrosion. New cables may be in order. Corrosion/rust can be such a pain in the ___! Then U got UR relay and other to recognize. Many times this corrosion is so on creeping there will be heat build up in the area that will damage the connections.

 

I got my starting system triple grounded. Be sure the ground from the battery to the starter is new and get rid of that garbage battery-frame-starter cable that keeps rotting.

I have a short 4ga cable from the starter bolt to the frame with a clean spot I grounded and painted and I also have a 4 ga body ground from the frame to the cab. I have another 4 ga cable from the battery to the alternator bracket and I haven't had a single starting issue since.
