I changed the bolt to a 3/8 brass and ran the cable to one of the starter bolts. The starter spun over with new life, who needs 8v or 12v for that matter. We generally can't get to the ground paths and they've been rusting away for 90 years. Naturally they slowed the current down somewhat.

My car has the main ground cable running right from the battery to the top starter bolt. A 7 year old neglected 6V battery still spins it over like it was new. I use the stock ground on the frame for an auxiliary ground.
