Replace fuse when engaged the fuse blows and motor shuts down

There is an actuator motor located on the transfer case. It selects range; hi neutral and lo and engages the front differential. There is a second clutch actuator motor on the front differential that engages the front wheel hubs.

You will need to disconnect both motors to eliminate electronics. It could also be you have an abraided wire to either the transfer case or the front differential. If unplugging both actuators doesnt stop fuse blow, you will need to test for signal or power to ground shorts.

What fuse blows ? The four wheel drive switch is a input to the GEM - generic electronic control module , low voltage ! There are a few different relays, a shift motor on the transfer case . There could be DTC'S - diagnostic trouble codes stored in the GEM module . You can find free wiring diagrams at http://www.bbbind.com/free_tsb.html Do you know how to do basic automotive electrical testing ? When you turn the switch to engage the 4X4 , the GEM see's that input an then energizes a relay to engage the 4X4 . Knowing which fuse blows would cut down on the guess work !

Wild guess here, had a similar problem on my 2000 4x4 blazer, has an electric motor on transfure case to swith it into 2h, 4h, and 4l, would blow the fuse every time when switching, did is to replace the motor. Just confirm your fuse that is blowing feeds that.

If the motor is running then the fault must be with either the clutch on top of the motor or the blade clutch it engages with.

Sounds like you have the starter wires hooked up wrong and to continuous power. If starter shuts off with the key now, but wont engage the motor, you may need shims so that the starter drive lines up with the motors fly wheel

Husqvarna uses an electronic clutch to engage the mower deck. When the clutch works itself out of adjustment it will quit working. Sometimes it will blow the 20 fuse and the tractor will continue to run, but the blade won't engage. When you then shut off the tractor it won't crank again until you replace the fuse. When you attempt to engage the blades again, the fuse will blow again.

There is a relay inside of the ABS motor housing that can stay engaged making the motor run continuously without the key in the run position. If this is the problem the only fix is to replace the Brake Pressure Modulator Valve assembly. You may also may need to replace the Control Module that is attached to it.

The motor can be unplugged from the module and will shut off. The ABS light will stay on until it if fixed properly. The other way to shut down the motor is to remove the ABS fuse in the underhood fuse box.

The ABS module and BPMV are expensive and the brakes will have to be bled. Junk yard parts can be cheaper if your capable to replace them.

You must have a short circuit ,try disconnecting things start with the heater element, disconnect one wire see if it still blows...next try motor plug, until the fault clears at least this tells you what the problem part is.....

If you blew a fuse you could have a grounded wire someplace. Check the wiring on the solinoid, on the battery, on the lights and anyplace there could have been a bear spot rubbed. If the flywheel does not engage check the flywheel gear on the end of the started to see if it is chewed and worn. These can be replaced easily,
