Fuse #6 Blow Instantly

OK, so I´ve been on this for a couple of hours, so I am going to ask for some help here.

 

Fuse #6, controlling indicators, horn and "back-up lights" blows instantly. Tried removing everything related to any changes I have done. With the car in neutral(so no reversing light on) and not using any indicators, the fuse blows once I turn the ignition to "On". I am pretty certain that means I have a ground/earth problem somewhere. So if anyone could point me in the direction of what wires I can disconnect/test to find this bugger, I would be very glad.

Using a multi-tester and with the blown fuse removed.  Turn on the key and if you don't already know, determine which side is the source side (+12V) and which is the load side.  Then key off and using the resistance scale the load side should show zero resistnce (dead short).  Disconnet loads on that circuit until you find the fault.  Better to test than to keep blowing fuses.

I believe my same problem was discovered as a fault with the heater fan switch.  I lost my horn and signals because the fuse would blow instantly.

If you don't have a multimeter you can remove the fuse and replace it with a 12v bulb like a headlamp bulb. This provides some resistance to the shorted circuit. The bulb will light due to the current flowing through the short. This will give you a chance to find the fault. Check everything connected to the circuit, following the wiring if you can. As previously said disconnect the circuits at the fuse box to try and isolate which circuit the fault is on. The bulb will go out when you have found your fault (and everything else is turned off)

 

Good luck and report back

I hate electrical issues :)

 

What exactly had you done before the fault appeared?

 

Good luck,

+1 ray .... I hate electrical issues.

 

SWAG .....  Hazard button ..... it is somehow in the circuitry for the turn signal indicators.

 

Cheers,

Update:

 

Removed the fuse box, and tested #6, two brown/white wires joined together. Went directly to ground somewhere.

 

Disconnected indicator relay, heater fan wires, hazard button, reverse light switch(wires hanging loose now)

 

I THINK the last time indicators worked was this winter, towing the car, with the new enigne in. Since then I have installed an electrical fan on a switch, not wired into the original loom. Also I have the MegaJolt, but that too is wired seperatly. Disconnected all wires there aswell.

Update again:

 

Found the problem. It was the ground wire attaching to the bolt on the heater box. Stupid thing. Spent three forevers fixing that box, and putting in a new fan, and then I can´t use it. Bah.

Vote #2 for a loose reverse light switch connection on the tranny tunnel.  That was mine.
