Topic: modern solenoid 39

  relatively new button solenoid...relatively new dash starter button. solenoid button works, but dash button suddenly stopped working during start. All connections clean. My understanding is that the dash button supplies ground. So, is it worthwhile trying to diagnose the solenoid issue it or just buy a new one? Are they all junk?

  Try grounding the center terminal of the solenoid. It should pick and activate the starter. If not, replace the solenoid, if it works, check the mounting of the starter button, paint may be keeping it from getting a good ground.

  Put an ohmeter between ground and the wire to the button. If the needle swings when the button is pushed, it is OK, or put a jumper wire between the solenoid terminal that connects to the button and ground to see if the solenoid pulls. The dash starter button depends on the clips that hold it in place for a ground, and as TomO says, the paint (or other crud) can isolate the button. Starter solenoids are rarely at fault, as they operate only when the engine is cranked. More often, any problems arise from loose connections. If the starter button is old, it may be the culprit. They are usually not quality switches.

  The new starter buttons are poop. If that's all you can get hold of, I suggest you solder a wire to the body of the starter switch and attach it somewhere nearby. The dash panel to cowl bolt is close and a good source of ground.
You will be amazed the difference this little modification makes.

  I did the suggested test of the solenoid and it was good. Crawled under the dash with mirror and checked the dash ground contact of the starter button. It looked ok, but took it out and expanded the copper grounding band just a hair. Then sanded the dash hole a tad until bright, shiny metal at the band contact area. As Jackie Gleason used to say "And away we go"! As usual, thanks a million!

  We use the NAPA 6 volt solenoids, and have yet to find a bad one. They are the "universal" type that brings out both sides of the relay coil. If you have an unaltered car, connect one of the small terminals to the battery input side of the unit, and the other side to the button.
