1955 was the last year for the Ford 6-volt, positive ground electrical system. I think Volkswagen was the only mfr to continue using it clear into the '70's.
On your coil, the distributor wire hooks up to the positive terminal of the coil. The ignition wire hooks up to the negative terminal of the coil.
After you reconnect the battery properly, you will need to re-polarize the generator.


Don't ever take these old cars to ANY shop to have electrical or ignition work done. Those fools always hook up the test equipment negative lead to ground on everything and then scratch their heads trying to figure out what went wrong. As soon as y6ou realize what they have done, you pull your hair out. Never take for granted that the shop fools know ANYTHING.
