  • starter solonoid?
  • Hey everyone - Still having starting problems but it looks like a compression issue. Not too surprising. Anyway I went to do a proper compression test this morning and when I hit the starter button all I got was a faint click. I got out the multi meter and seemed to narrow it down to the solenoid. Oh, '48 8n, front mount, 12 volt conversion. I jumped the solenoid and the starter engaged. Went to NAPA and got a generic 3 pole 12 volt solenoid. Put it all back together and nothing. Not even a click. Jumped the solenoid and the starter engaged. I energized the small pole and the starter engaged. What might I be missing? Does it matter which end of the solenoid goes to the starter? Did I ruin it be wiring it backwards?

  • Thanks you guys - that explains a lot. The starter switch of course tested positivity for continuity to ground and I couldn't understand why I had continuity from the small terminal to ground. I figured, wrongly, that a 3 pole solenoid was a three pole solenoid. I was in a rush to get this compression test done on a relatively warm day. I will get a proper 12V 8n starter solenoid.

  • A six volt one works good, may have trouble finding a 12 volt one that does not reqire power to the small terminal. But then I have never looked. both of my 8ns have the OEM 6 volt solenoid ands both of mine are converted to 12 volts.

  • The generic solonoid uses 12volts to the small terminal to activate it. The 8n solonoid uses ground to the small terminal to activate it. You need a ground activated solonoid to properly use your 8n starter switch that is mounted on the transmission with the neutral lockout. The 8n switch just connects you to ground through the frame of the teactor.

  • If it energized when you applied voltage to the small terminal, then you have wrong solenoid. You need one that is energized when you connect small terminal to ground.
