My M has 12 volt distributer and I have a problem. I got the tractor running great but I by-passed the alternator (didn't know if it worked). I brought the alternator down to the shop and had it tested...it works fine. I thought I would wire it in this weekend. I followed a diagram I found on this sight (had to get a ballast resistor though) and now:

When I turn the tractor over the Ammeter displays positive volts (@12 vlts) then when the engine fires and initially starts (1 second or so) the Ammeter quickly changes to -13 volts or so and the engine dies quickly. Has this happened to anyone before?

Regards

The ammmeter reads amps, not volts, so I am going to assume that's what you mean.
It sounds like the motor starts when you crank it and dies when you let off of the starter. If that's it, check the wire from the ignition switch to the distributer. It might be on the wrong side of the switch and loses voltage when you let off the starter. A quick check with a voltmeter can confirm or rule that out.
It also sounds like the ammeter is wired backwards, that's just a matter of switching wires on the back of it to fix it. Let us know if any of this helps, Good Luck!
