OK guys, I need help. I am working on a CC 127. My brother-in-law put a new wiring harness, new voltage regulator, and a new key switch in it. It has several issues but I started with the issue of the battery not charging. I assumed that was an easy fix, just polarize the voltage regulator. I tried that and smoked the voltage regulator. OK....it's an electro-mechanical device so I attempted to fix it by replacing the wire that I thought I had burnt. When I hook the battery up now, it rolls the tractor over without me touching the ignition key. Next I suspect either the wiring or the switch is the culprit. I have checked and double checked and they both seemed ok. So, I ordered a new voltage regulator and installed it. The tractor still rolls over when I hook up the battery. The problem is not the solenoid. It appears voltage is feeding through the regulator to the starter although I am surprised that it will carry enough current without smoking something else. Any ideas? Please!
