Ignition Switch

[Calibre]

I have just finished wiring up the 9N with the 6v positive ground alternator.

Everything works fine and the newly rebuilt engine purrs like a kitten.

Howerver, in order for the alternator to charge, the #1 terminal on the alternator needs " positive excitement", which is ground in this case.

Was thinking of some sort of ignition switch that has separate connections for the ignition side of the circuit and the other for the "excite" terminal on the alternator. Is there anything like this for my application?

Basically, I am trying to eliminate a seperate switch for the #1 alternator terminal. (Something I know I would forget to turn off someday and drain the battery!)

Thanks in advance for the assistance.

Use a small relay operated by the ignition switch to complete the circuit.

Or, a momentary contact PB switch.

Thanks Bob ... two good suggestions that I didn't think of.
