new battery does not hold charge..suspect generator or solenoid which appears to have been recently replaced. That is the solenoid appears to have been replaced recently. Acquired the tractor just two months ago.

to test the generator, ground the "F" terminal to the frame to bypass light switch resistor. if tht works, you have a bad ground. next jumper around the cutout relay, which is really connecting the A terminal of the generator to the amp meter. you can also put a volt meter across the two terminals of the generator with the F grounded and relay bypassed and see what voltage you have. if both of those tests fail, the generator is bad.

Do you mean the cut out on the generator? Is it still 6 volt?

If it has a solenoid it was added but it still should not be a draw down there. If it has been changed to a 12 Volt GM alternator it could have an internal short.

Or not wired correctly in the box under the steering wheel

Pull one of the battery cable off then put a meter or test light between the battery post and cable. If you get a reading then you have something that is taking a draw on the battery if you don't then you have a new bad battery. If you get a reading take one wire off at a time till you find where the draw is coming from

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 ...
