Blowning fuses 2006 cub cadet blows 25amp fuse disconnect regulator rectifier will run soon as i plug it in fuse blows mechanic at cub put my reg/rect on another tractor in shop it ran two white wires go somewhere under plate probably to stator any ideas

Pull the connector from the back of the PTO switch and the 4 wire connector at engine. Replace fuse. Turn key to run.

Did fuse blow? No, turn key to start and back to run.

Did fuse blow? No, plug in engine connector.

Did fuse blow? Yes, likely shorted regulator or safety miswired.

Plug in PTO switch.

Did fuse blow? Yes, likely safety miswired.

sounds like a bad short some where. from my experience i found that of i unplug the magneto and the pto clutch. it wont blow the fuse. plug one in at a time and when it blows that is your problem. could be several things but that is what i have found.

A fuse blows because the circuit it provide power to has a shorted component or wire.

Are you sure it's blown? Run two jumper wires from the battery or power side of the starter solenoid and energize the clutch. If it energizes and clicks, that's eliminated. Did you blow any fuses?

it is blowing fuse ,it means there is some short circuit ,try to find short circuit ,

There are several things that can cause the fuse to blow. PTO stands for Power Take Off and most likely this will not be the problem unless it blows the fuse when it is turned on. What you are saying is the fuse is blowing by just turning on the switch will be a short which can be anything from a pinched wire, shorted diode, short in the stator. bad voltage regulator.etc

you have a wire that is grounding out, I would check the wire coming from the connector on the voltage regulator to the battery. This is the one in the middle position, look for a rub through and tape it up.

Blown fuse. There is a fuse somewhere thats blown. It will be about a 15 amp in a fuse holder either back by the battery or behind the dash. U didnt specifiy the 100 number If thats a starter-gen it could be a reg- relay issue.
