My negative battery cable and the cable from the starter to the starter solenoid, are strapped down to the frame next to each other. I replaced both of these cables, and when I did so, they were both stripped of insulation underneath the strapping. They were both so black and filthy that I assumed the strapping had worn through the insulation, so when I replaced both cables, I left the insulation in-tact here. But I think I recall somebody saying in a thread that these cables should ground to the body here. Is that correct? Should I strip the insulation off where they get bolted under these straps to the frame?
Yes, it's an easy way to pick up the extra frame ground. The stock cables had the strap soldered to the cables. But, to make things easier, strip it back and put some contact grease on it to keep moisture out and make sure it makes good contact with the strap.
You are part right.
Is this on a 300 six motor? It sounds like it so here is what you should have.
The cable from the solenoid to the lug on the starter DOES NOT get grounded to the frame.
If you look you should see, or maybe not, the cable holder should have insulation besides the insulation of the cable.
This holder is just that holds the cable so it will not hit the hot exh. pipe.
Now the ground cable and its no insolated holder should go on the cable with the insolation removed and solidered to the cable / holder.
This is the frame ground as the cable makes it way down to 1 of the starter bolts and the motor ground.
Old cable is the lower one. Upper has the tab that bolts to the frame, I had to make it.
Where the cables bolt to the frame. Top is the insolated power cable, Bottom is the frame ground cable.
