JD 265, frying wires to starter
|Jeremy||I have a JD 265 with a 17hp Kawasaki. It will not turn over and it literally fries the small wires that go to the main post on the starter. I was able to put a toggle switch in place of the key switch and it turned over fine, but no spark. Key ignition won't turn it over. It's not a JD key switch, but it looks like the old original that was junk.
Today I put in a new/used motor and replaced the entire wiring harness that I got off EBAY. It fried the wires again when I turned the key on. Any advice???
|Dale G. Basgall||Jeremy, in regards to the "small" wires that go to the main post on the starter.
First of all, small is your definition of wires and leaves one questionable of which wires you consider small however, I will explain what I interpret from the text above and hopefully can assit you with a solution.
There are two components, one the starter motor, and two the starter solenoid. The starter motor has one threaded lug that only requires a direct 12vdc positive input to make the motor shaft rotate, this will not pull the starter bendix gear into the flywheel so the starter motor just spins.
When there is a solenoid attached to the starter motor usually the lug on the solenoid closest to the starter motor is attached onto that lug going into the starter motor. That bottom lug on the starter solenoid that attaches to the starter is called the solenoid load lug in this application and that is attached via connection onto the starter motor lug.
The starter solenoid has one other lug that attaches directly to the positive lug on the battery itself, it is always hot at all times and in this application called the source lug and provides the electrical potential to run the entire system. The smaller wires attached to that source lug on the starter solenoid go directly to the ignition switch and furthered through a closed ignition switch onto the entire rest of the electrical system on your equipment.
There is one other wire and it's probably purple and it goes from the ignition switch start terminal to the solenoid coil input wire, and thats the only one left, so if thats all ok, check your ground cable also and just make sure it's making a good ground.
If you can't solve you problem after you go through these steps write back on the forum, this doesn't seem to be rocket science in this situation.
