1450 charging problem
 

Hey Cub fans, just got through rebuilding the engine on my 1450. thought I did everything right, but it is not charging. The Stator is fairly new and used to charge, now nothing. The engine is now basically new and runs like a champ, thought maybe it was a ground problem, so added another ground strap, still nothing. I'm wondering if it might be the resistor (probably not the right word) that sits on and partially inside the flywheel case. My question is how do you check the Stator and the resistor. When the engine is running at operating RPM, the Voltage guage runs straight up in the middle, but engage the pto and then it runs at a slight discharge. I would hate to think that I'll have to pull that motor out again to change that Stator. Hoping you guys will have some ideas!!!!

Is your rectifier/regulator well grounded? Maybe a little paint or something might be preventing it from making good contact? If you have a voltmeter, put it on AC and measure the voltage across the stator while it's idling. Expect less than the 24VAC, but you should see something. You can measure it across the two outside terminals of the rectifier/regulator (from one terminal to the other). The center pin should connect right to your battery. You should be able to measure +12VDC with respect to chassis on the center pin with the engine off. If you disconnect the center pin, you should measure a DC voltage on the module center pin with the engine running. It should vary from a low voltage up to 13.7VDC at 3/4 throttle and higher. If you have AC, a good ground, and no DC on the output, your rectifier is bad, and you don't have to pull the engine down hopefully. Good Luck with it!

Roland, that is a very nice diagram.
