Kubota BX2360 keeps blowing ACC fuse

[Laps]

My 5 year old Kubota now keeps blowing the ACC fuse as soon as the ignition switch is engaged. When that happens the gauges don't work nor the lights nor the hour/rpm meter. I have looked for obvious shorts or pinched wires and can't find any.
Checked the battery connections also.
Any suggestions?

What is running off your account circuit?

ACC circuit, stupid autocorrect.

I don't have any accessories hooked up, no accessory lights etc. As soon as I turn the ignition switch to start the motor the ACC fuse blows. So that leaves me with no dash gauge readouts, no lights, no meter/hour readout. The tractor still runs normally though.

Exactly what position does the ignition switch have to be in in order for the fuse to blow? RUN, START, or PREHEAT?

It will blow as soon as the switch is turned to the first position, which is the preheat. The preheat indicator light DOES come on, indicated on the dash, but that is the only indicator that still works on the dash.

I would start following wires, you may have one that has rubbed through and grounding out. Also try unplugging anything that does not work once the fuse blows. If the fuse no longer blows after you unplug something, you have found your problem.

Correction to my post: the first position is RUN, and it blows at that position. The next position is Preheat, and the third position is start. Sorry for the confusion. Thanks.

Thanks, I'll do that. I wonder if it could be the ignition switch it self?

Not likely, as it just passes current through it. If that were the case, it'd blow the fuse supplying the switch.
