I have disconnected the rectifier ( all the wires including the one going up to that red eyelet) and the fuse blows as soon as you put it in. The key is in the off position. Its not the rectifier. I have gone through all the wiring and can see nothing amiss and no areas where its been chafing.

Scratching my head but next is to disconnect starter although the main feed does not seem to go through the fuse. Will start to look at the ignition switch. I have some help who is a mechanic so hoping he has better luck. I have the 2014 wiring diagram ( lost on me) and it printed so small its difficult to read. Where can I get the earlier one, pre 2014?
