Mark, what I told Steve corrects what in my opinion are errors on his drawing BUTTTTTTTTTTTTTTTTTTTT even as he had it shown if you depress a start button or turn a key type switch to the START position it should still have energized a starter solenpoid to make her crank. His way still had battery power to the BAT input terminal on the switch, I was just correcting where it got its voltage from (ammeter versus VR L terminal).

If it has a starter solenoid when you depress a push to start switch batetry voltage should get sent to the small S activation terminal (NOT any I terminal like on Ford type solenoids) on the solenoid making it pull in engage. Similar if its a key type when its in the START battery voltage gets sent to the small S activation solenoid terminal so it engages ANDDDDDDDD those switches need an input voltage on their BAT terminals.

If there with a test lamp this would be easy to diagnose but I cant explain everything over the net iof youre not already somewhat electrically experienced sorry

I have posted my "Perfect Collection" on the Farmall board. List any brand preference but keep ... [Read Article]
