  1. Why is the 30amp fuse blowing everytime I put a new one in without key being in swtch on My GT3000 25Hp Kohler Pro V-twin?Thanx friend for your Time.William.

  2. I continue to blow fuse on a craftsman mower with cv22s kohler engine.  I have had trouble with intermittent starting in past, and now not at all, fuse is blown. I over the course of isolating the short I replaced wiring harness, switch, ammeter, solenoid, and regulator /rectifier as well as plastic connector to the regulator (not the wires). It continues to blow the fuse. I can get the tractor to start by disconnecting the regulator/rectifier, and despite the reg/rectifier being new, it blows the fuse If I try to start it with it connected. I assume the engine wiring harness is good since the tractor runs when regulator rectifier is disconnected, (as were everything else I replaced most likely) ?  Any idea of what could be causing the short, I assume one of the wires leading to the reg/rectifier? I appreciate any help you can offer.

  3. I have isolated the short in the red wire coming from the fuse holder to the ignition switch. Question is, how do you replace the red wire?
