Super M starting issues

Nathan Harvey · Jul 31, 2013

hey im new here, i just have a few questions and wunna see if ya'll can help me. My super m's amp meter was smoking up yesterday and there was a burning smell the wires were hot too. The tractor turns over but when im turning it over the starter is BURNING hot and so now is the amp meter? idk if the amp meter has anthing to do with it starting or not. I was also thinking maybe the regulator is bad cause the wires to it were burning hot too, but i have no clue. If you can help me that would be great. thanks

If you have not, disconnect the battery Now. Then come back and I will give you info. Jim

If the voltage regulator sticks (cutout points can weld together) the wire going from the starter switch to the amp gauge, and those from the amp gauge to the regulator, and from the regulator to the generator, and the generator itself can burn up.
All those wires and all those components are now suspect of being toast. If the starter motor Frame (metal) was hot it is also possibly toast.
Disconnect the battery !!
Disconnect the wire attached from the starter switch starter side that goes to the amp meter. Put a test light on the connection and the terminal you removed. Charge the battery (while disconnected). Then connect remove the big wire from the starter switch and make sure it touches nothing. Put the battery terminal back on. Use the loose end of the cable to touch the start switch. If it sparks, do not attach. If the test light lights up. Do not attach it. The regulator might be shorted. disconnect the Arm wire from the gen and keep it from touching anything it the test light stays out it is pretty certain the regulator has welded cutout contacts inside.

So what battery are you using and what polarity sounds like you need some help from an experienced person before you have a fire and other damage.

Ah hah! This may be the issue I've been facing with my 450LP and couldn't get figured out. I kept blaming it on the starter.

I think I've got an extra regulator laying around to try out.

Amp meter *should* have nothing to do with the starter, unless some idiot wired the starter through the amp meter!!!

One fat cable should go from the battery to the starter switch, and then to the starter. Early Super Ms have a starter button that you kicked, so there is a short cable from the switch to the starter. Later Super M's have a starter button mounted directly on the starter, where you pull a rod, so there is no extra cable.

The other fat cable should go from the other post on the battery to a bolt on the tractor's chassis somewhere.

The fat cable should NOT go up into the wiring box on the steering post.

I disconnected it already, and well I had it running really good a month ago for a couple weeks. But hen the tfloat had to had to be replaced so I bought a float from "yesterdays tractors and but it on. Then it turned on!but I shut it off to put the bush hog on then went back and tried to start it again but it wouldnt start. I was thinking it might be the float? Idk! Aaahhh so confusing. Im 15 btw and my gpa gave me his tractor"s when he passed.
