I have started the 12v conversion on the 41

I will use a Lucas Flathead distributor ( from the English Pilot car - this used the 24 stud flathead ).

The Lucas Dist had 1 wire stud in the alloy Dist housing.

My question is can someone help with how to wire the
A). 12v coil ( has 2 threaded studs )
B). Then the coil to the Lucas Distributor's 1stud

My factory 41 Dist simply has 1 wire going to the coil ( which us mounted directly on the Dist housing. I think this 1 wire from the factory setup should go one of the two studs on the new 12v coil, what would go on the other coil stud?

Thxs for any help,
John

I assume you're going 12 v neg earth; in which case the wire from your ign switch goes to the pos term on coil, and a wire runs from neg term on coil to that stud on the dist.

The engine may be a replacement, my recollection is that Pilots had 21 stud engines based on the 37 Ford, but with better exhaust manifolds, Lucas dissy and better crank. I may be wrong. Any ways, Brian has nailed it. Pay to use a ballast resistor in the wire from ign to + on the coil. This reduces the coil voltage to stop points from burning.

The old helmet type distributos had one internal connection for the breaker points and one external for the ignition wire. The round can type coils will work either way but polarity will have to be tested to get it correct. A person can start out with the bat/ign wire connected to the negative terminal and the distributor breaker wire connected to the positive terminal if you are running 6-volt positive earth. If you are running negative earth, the oposite applies.

Does your coil have a label saying that it is supposed to be used with a resistor? If so then you need to run a wire from the solenoid to the resistor and then to the coil. The other terminal on the coil goes to the distributor.

No my coil has an internal resistor.
BTW - the new 12 volt conversion will be Neg Ground

Brian helped me out on the coil wiring - thxs!

Will report out on how it all goes - after the weather warms up a bit.
