Understood. Thanks for the info. And I attached 2 pages of wiring diagram that shows exactly what you describe.

So a new solenoid that has 2 small post possibly requires a jumper wire...assuming the coil isn't internally connected to the battery + post.

Edit: Also here is a good thread with various Part Numbers of solenoids "relays" that will all do the task well....it's up to you to determine if you are scared of the PN police.: https://forum.cessna170.org/forums/viewtopic.php?t=13384

Ron, (Stewart that is) I finally received my new Lamar P52-0034-1 Contactor. Just like the one shown above (4 posts)
First, thank you for all your help.
One more problem:
Could you or would you be so kind as to provide me with a diagram of how the wiring should be connected to the new contactor.
The new one shows the battery terminal being connected to the large terminal on the left side of the contactor. Old one was connected to the right side.New one shows the load terminal being connected to the right, large terminal.

Thank you, Dalton

I think I got it.

The positive cable from the battery goes to the large terminal on the left of the relay.

A second cable goes from large terminal on the right of the relay to the starter solenoid then to the starter.

The small wire which is the ground goes on the small terminal.

Am I right?
