Replaced the ignition and PTO switch still blowing fuses when I turn to start. I pulled the negative cable off battery and put test light on post and to wire and no light until I turn to start position. Hook negative cable back on turn to start pop fuse. Now when I unplug the yellow wire from the solenoid the fuse doesn’t pop but still nothing. Traced that yellow wire to brake lever plug. Suggestions? Oh and I have replaced the starter, solenoid, battery and all safety switches. I have pulled the entire harness and see no bad wires????? ?
