Re: '54 turn signal problem, need diode?

If you have a Massey Ferguson tractor dealer around or a Ford tractor dealer they usually have 1N5408 diodes to put in line in the exciter wires for an alternator.

Remember that diodes are one way valves for electricity so you want the current to flow through the wire to the light and not from the light though the wire.
