a engine will run hooked up backwards but not 100% from my experience 1 case is a 1952 farm tractor that had been changed from mag. to bat ing. it foul plugs i fought was this longer than i would like to admit so fowled the distributor wire back to coil it was hooked up backwards switch wires around runs perfect no more fouled plugs HAPPY WRENCHING
@@Thunderbird1968 I wired a coil backwards once when tuning up with points, rotor, condenser and I replaced the old coil with a new chrome one. At first I thought the Tach quit because of faulty parts, but it was me switching the coil wires. i think the ground had a Red end from the previous owner or something that threw me off.

Just for information, my Ford of Dagenham, England, Mk1 Cortina 1500cc has positive earth - 1962-1966 model.

Yeah, I did that once.
