I finally got my fuel delivery issues straightened out by adding the electric fuel pump but now the tractor will cut out and loose power randomly. What I mean is it looses electrical power, the fuel gauge cuts out along with all other dash lights, it sputters and quits then will not restart. I looked over the electrical system and found a burnt connector at the regulator/rectifier. the connector that was burnt was one of the AC lines coming from the 15 amp stator.

My question is, could the regulator be causing the electrical system to fail?

I disconnected the regulator and the tractor runs fine until the battery goes dead.

When i get the chance I will run tests on the regulator and stator too see if they are good or bad but right now I'm puzzled as to why it will run fine for an hour or so then just act up and quit.

Magnum 20 in a Sunstar 1691381...once started, there is no electrical reason the engine should stop except:
- the ign. sw. turned to "off" OR
- the transmission sw. not in neutral AND the seat not occupied

So, I don't know any way the regulator being bad would cause the engine to stop.

If there is a short circuit in your B+, strange things are going to happen. If the magneto kill circuit is part of the strangeness, then maybe it is getting a "kill" signal. You could pull the kill wire out of the engine plug to see if it still dies. I guess I would get the regulator situation straightened out and go from there. :confused:

Thanks G-1, it turns out the regulator/rectifier is bad. Found a new one for $25 and its on its way. I tested the stator and it was good, no other issues with the charging circuit.
