When I plug in the wire connector that goes to the Stator on my 16HP John
Deere Sabre Lawn Tractor, the connector gets real hot to the point of
smoking. It appears there is a diode in the wire right after the connector.
this connector has two wires one of which I think is for powering the
headlights, the other has a diode in the line.
If I leave the plug disconnected, the tractor runs and operates , however, I
the battery will soon go dead. Any ideas on what is wrong or how to fix it?
Replace the diode?
Disclaimer: Since I don't have a wiring diagram for your specific
model, the following is just a educated guess.
One of the wires come from the ignition coil on the stator. This wire
grounds out the igniton coil so that you are able to shut down the
engine by grounding out the igniton system. It is also the wire that
is going to all the safety shut down switches.
The other wire comes from the charging coil on the stator. This wire
charges your battery (as you earlier suggested). It sounds like what
you and the others suspect. The diode is fried. To check it..........
You should have continuity in one direction and not the other. You may
have also fried the charging coil on the stator. To check that, you
should have continuity from the connector to ground. If the wire is
getting hot, your charging coil may be ok.
