ri702bill 10,336 #1 Posted 1 hour ago I've gotten into the habit of adding a second ground cable to the starter housing. Simple, neat and effective. The fastening points already existed... why not? 3 Share this post Link to post Share on other sites
ebinmaine 75,073 #2 Posted 1 hour ago I've half jokingly told folks more than once that when your wiring harness starts looking like black spaghetti you have just enough ground wires. On the starter I've used the main mounting bolt as the engine ground connection. Share this post Link to post Share on other sites
953 nut 62,642 #3 Posted 1 hour ago I run the battery negative wire directly to a S/G mounting bolt on the older ones and like @ebinmaine go to the starter mounting bolt on the newer ones. Cast iron is a fairly good conductor of electricity, but not as good as copper. Silver is a better conductor than copper and gold is a much better conductor than aluminum but then we have to consider cost, so copper it is. 1 Share this post Link to post Share on other sites
