  • If not, I guess I can apply 6v and see if it clicks? If so, it's 6vdc.
  • If no click with 6vdc, then try 12? If it clicks it 12vdc!

Sorry to keep bugging everyone, but trying to gain as much knowledge as possible before we get under it tomorrow evening. Don't want to burn anything out that may be good either!

Thanks again for all help!
Hmm...

Start by looking for a part number at the end of the solenoid. I posted a link which shows a solenoid with the number and also has a picture of a page from an old Motor's Manual which lists solenoid voltage by part number. If you are unable to read the number, measure and record the resistance of the coil and report back (Hint: remember that one terminal will be completely open).

You may not hear a click from the solenoid. Remember that I mentioned above the solenoid only puts spring pressure on the pawl. The pawl may not shift into position unless the input or outut shaft is turned.

I would not blindly apply 12V to this component. Replacements seem expensive.
