[Roadsters] one wire

[Pat Horne]

There isn’t one. They didn’t show until the 280Zs started using volt meters. You can add one if you like, like the brake test light (if neither side of the light is grounded). 

Peace,
Pat

  I remember reading somewhere, that the Datsun gauges were just idiot lights with hands?

  So now I need to figure out where the charge idiot light is on the dash.

Thanks,

Paul

I’ve seen many where they just run a wire from that terminal to the Batt lug on the starter. The other pin is not needed, or is mainly used to run the idiot light that tells you when the alternator is not charging.
