I'm getting 12.43 or so volts from the middle rectifier wire When the tractor is running. The wire suppose to run to the battery. So if I hook it directly to battery it should be fine?

At what RPM, I get almost 14V on mine at 1/3 throttle, after I grounded the regulator case to the chassis. The regulator output needs to go through the key switch, Otherwise you will kill the battery when not running.

OK, Most I have worked on goes through the SW. If the diagram is correct, follow it.

If you got straight to the battery, there is a chance it can drain the battery as it sits. Mine all go through the ignition terminal on the switch

I noticed there is no fuse in your diagram. EVERYTHING I have ever worked on has a fuse. What model sears is this? So I can make sure NOT to get one. One short and the whole thing will go up in smoke.

Looked at that wiring diagram and there isn't a fuse shown ? Also you can turn the headlights on without the key being on .

Post the model # and I'll see if I can find the correct diagram. The one you posted doesn't look right.

 

The 917.XXXX number
