I recently picked up an early 70's IH cub 125 hydro in great shape. After running it a few hours the starter stays on After the tractor is started and broke the belt. Can anyone tell me what's causing this? I am hoping not to have to by a New starter/generator.

It might be the voltage regulator . I have seen that if the contacts stick closed in the regulator it will crank the engine over . That would be the first thing I'd check .

It doesn't do it all the time if the switch is in the On position only when you crank it. I don't know if that helps tell what it is.

It could be the ignition switch is bad and sticking in the start position.  It could be the starter relay sticking closed.  Or like Jlaws said it could be the voltage regulator.

Here's a S/G Repair Manual. Thought I had uploaded a wiring diagram for these. I do some snooping for that.

 

Found a wiring diagram:

Hope this helps you get it figured out. If it is the regulator, there are a lot of different types, so make sure they will be a match for yours.

Jlaw was right some contact cleaner in there and it seems ok. Hopefully get me through the year and hopefully this winter I will put in new points condenser regulator and all that stuff. Tractor is in great shape runs good not a bad deal for cutting down a tree for someone.

Hopefully, one of the sponsors will have access to those.
