Default Re: Why a Resistor?

i'll have to put my multimeter on the connection to the coil both with ignition on and the engine not running and with it running, both cold and hot. just to see how my car is set up, as it may have been altered in some way.

i'm beginning to wonder if the massive misfiring that consistently occurs in my original '41 engine, when fully warmed up, is being caused by the original style coil on my "diver's helmet" distributor, possibly involving a ballast resistor. as in is it working? is it not working? has it been disabled maybe? IDK

or i might simply buy one of those "modern canister coil" conversion kits install a modern 6v coil and run a wire directly from the battery to the coil, in order to bypass any issues involving a ballast resistor, altogether. it would also eliminate the possibility that the wire to the coil is some sort of "resistor" wire too.
