Friends 175 problem

It's a gasoline model with the resistor mounted near the solenoid under battery. It won't crank. When he runs a test light from ground to the terminal with one of the resistor wires it will then crank when he pushes the button. He's 45 miles from me so I haven't seen it myself. He just installed a new solenoid because it wouldn't crank, thinking that would fix it. Grounding issues? Or wires not hooked up properly? Once it starts it runs good.

Switch the two small wires. One is for a ground.        MACK

Put The Small Left Wire On With The Right Wire Then Ground The Left One

Either push the clutch in to 'make' the switch, or replace the bad switch under the clutch, or the break in the wire going to the switch.

He said that switch was eliminated years ago. He was going check that jumper wire for a bad connection.

Would that indicate it's the wrong solenoid. If so, wiring it the way you suggest would still function correctly.

Thank you. Would you lose the extra zap to the coil for starting? I don't think it would matter too much to him since it doesn't get run in the winter.

OK thanks, I asked because I saw an old post either on this site or YT that had the same basic issue and someone commented that you would lose the extra zap for starting. It's been a very long time since I've worked on these tractors at the Allis shop. Since the early 1990's.

Thanks guys, I'm taking all into account. I'm for him getting the correct solenoid and throw that cheap NAPA one, assuming it's cheap.
