Hi, I've been scouring the board for more inforamtion on how to wire a 6V (positive ground) push start button using a relay, but no luck. Currently running a 56 Olds 324 in a Model A running 12V negative system, using an aftermarket wiring harness. I have: A: Push button start B: 50 something ignition ( Acc, off, on) for fuel pump. C: Kill switch for Mag. Right now I have the relay wired as follows: 87 ground 85 12V constant 86 Push button I can push the starter button, get the relay to click, but no voltage at 87 A or 30. Afraid to jump any wires and let the smoke out... Thanks in advance,
The push button don't care about voltage. If this is a old Ford button they were a one wire ground to work the solinoid. If your relay needs power to work you will need a 2 wire button.
