interesting: Not to be a nit picker , but the reading you are getting is 20/30 amps or volts, and you mention alternator? sure its not a generator, which has a regulator control unit mounted elsewhere. your last sentence "have to shut off kill switch gets hot" your wording/info has me puzzled we need more detail as to when you shut the tractor off (with fuel control) the ground switch gets hot? or does the series/parallel unit gets hot? if you are having a heat problem at the ground switch, there is a good chance the connection from switch to tractor is in need of service, clean and tighten to eliminate that possibility. Before starting the tractor take the main power lead off the starter solenoid from the batteries and with a volt meter you should have 12 volts from it to ground, when the ground switch is on and key is "on" if it has a on position besides just being stuck in the slot. Now when you turn the key to the start position, you should have 24 volts at the cable end to tractor ground, and when the key is returned from start, the 24 should drop to 12 volts. now you know the series/parallel switch is operating. The last time i had one fail the factory smoke comes out WAY to quick...:) I switched to 2 batteries in parallel for 12 volts put on a reduction gear starter as a replacement of the original, and it rolls and starts for the last couple years of winter. post back what you find and hope it helps.

Today's Featured Article - Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
