I have a wire heating up and wanting to burn that is going to the alternator (stator) . It is a black wire with a diode on it I think. I went to the john deere dealer and they first gave me a stator because they said that might be problem. It wasnt because i put new stator on and still same result. I took stator back.they checked old one and said it was good.rigged up some diode to put on it. I tried that and still wire wanting to burn up. I think maybe they give wrong diode? I have it figured out it can be only 2 things as all other wires have no shorts and this wire running from the stator is black, connects to a 4 prong plastic connector where it changes to red and goes to the solenoid, Is this wire suppose to be a hot wire where it connects to the plastic connector? I have photos of exactly what I am talking about if someone can help me I can send them the photos. It is in great detail taken with digital camera.
You really need the electrical diagram or schematic wiring showing the wires running from the battery through the starting solenoid to the starter motor. The ignition switch controls the solenoid. When you turn the ignition switch to start, the engine cranks by making the solenoid connect the big red positive 12 Volt battery wire connection on one side of the solenoid to the big red battery wire on the other side of the solenoid going to the starter motor. So get the operation and maintenance manual for your mower and see what electrical components are shown. If you can disconnect at least one of the diode's wire connections and measure it's resistance with an ohmmeter (Digital Multi-Meter, DMM is a volt, ohmmeter, ammeter), it should not read less than hundreds of ohms no matter how you measure it.
if it starts to heat up which means you have a high resistance somewhere -- the diode is used to make sure the flow of power goes in one direction check the diode and make sure it is pointing the right way
The Diode helps present day to pass in one course in simple terms. in the experience that your twine that the diode is connected too is burning up you have a bad diode. there is no longer sufficient present day to truly soften it down via fact the Milli-amps are so contrite that it takes likes 0.2 to furnish a trickle value to the battery. i could use an OHM Metere to examine this out to be greater gentle with your consequences and diagnosis. an on the spot short from the 12v resource could genuinely warmth it up and burn it out. i've got in no way see any twine soften in my history of doing mowers as a effect from a bad diode. there's a risk of a incorrect connection or a bad swap permitting present day to shuttle from one prong and that's uncommon, yet conceivable.
