Hi Bolters,
I keep finding references to two ground cables on a 1946 Chevy 1/2 ton. The first one is easy, fron the negative post on the battery to the engine/trans. But I keep seeing a reference to one that goes from the engine to the frame. Exactly where does this get attached?
Thanks in advance,
Possum
