1996 Jeep Cherokee Main fuse blows?

Main fuse blows when ignition switch is turned ON.



Main fuse is located under hood in engine compartment.

Its a 40amp bus fuse.



There are two possibilities


There are 2 "40 amp fuses". One is for the abs pump, and the other is for power supplying to the fuse box under  dash. If the Jeep starts and runs, then it is probably the abs pump circuit. It could be a shorted pump, or wiring harness between the pump and the relay. Try removing the abs pump relay and see if the fuse still blows. If it doesn't, then have the abs pump circuit repaired for a short to ground.

On some jeep models the ABS fuse slot will be empty,so in that case replacing the one only main fuse will help.
See below the fuse box diagram

2003 Chrysler 300M: Fuse 17 Blows?

Fuse 17 controls ABS controller and Transmission Range sensor.Also check the Climate control module and wires going to the climate control circuit board.Its a 10AMP fuse.


Well this fuse supplies power to several components. In this case it can be an intermittent wiring issue. If you are sure it is not a climate control and the wire that goes to the climate control, then you still have 2 wires out of the junction block that go to the ABS controller and Transmission Range sensor.
Remove the terminals ( one at time) from the C 9 connector at the Junction block to see which one causing a short.



To do this process manually you will need to find the C9 connector and disconnect it from the junction block.
Then remove ( pull out) #5 terminal White/Violet wire from the connector. This wire supplies power to the ABS module so your ABS won't work with the wire pulled out of the connector. Connect the connector back and operate you car and see if the fuse still blows.
If it does, then this wire has nothing to do with the short so insert it back and then remove #4 terminal with is White wire from the same connector and then plug the conenctor back and operate the car. This White wire supplies power to the transmission range switch and when you put in Reverse, the power is switched to the Back up lamps.
If fuse does not blow with the white wire removed from the connector, then you have a problem with either this wire to the switch or with wire that goes from the switch to the backup lamps.
Below is the connector pin out that will help you to identify things.

This details will help.
Thanks.

Circuit breaker trips or fuse blows?

This problem is noticed when appliance voltage is not handled by the electric supply of the place.The voltage issues causes this types of problems and needs to be inspected.
Well if you have Blown a Fuse/Tripped Circuit Breaker, FIRST, TURN OFF THE MAIN POWER SWITCH. Now, If a Breaker, simply flip the lever, the "Other Way" or, press the button, on the Breaker Body to "Reset" it. If a Fuse, you will have to withdraw the Fuse(s) from the "Holder(s)" until you find the Blown one, look to see if the Fuse Wire is intact, or, not.. a Blown Fuse will have the wire broken/melted. You then, effect repair, by simply using a length of the correctly rated, Fuse Wire. (Replacement Fuse Wire will be of different thicknesses, for different Current Ratings, usually, 5 Amps, 10 Amps, 15 Amps, & 20 Amps). Simply wrap one end of the Fuse Wire, around the contact, at one end, or if screw connection, then under there, & wrap clockwise, then, .make it go through the little hole/slot in middle, and then, wrap it around the screw, or wrap around the other end contact Then replace Fuse, turn the Power back on. Always do all this with nothing plugged into the power socket too. Now if the Fuse.Breaker "Blows" or "Trips" again, with nothing connected, you have a Wiring fault. Also make sure the Unit that caused the problem in the first place is repaired, or it, simply do it all again.
Electricity problems must be inspected by proper repair techs.Basic inspection is definitely advisable, but major repairing must be inspected/checked by proper techs.
Thanks.
