Popping 40 amp maxifuse! Not good! *solved*

Post by S10 »

The 40 amp fuse keeps popping and it's at ramdom! I thought it was the aftermarket alarm, so I had it pulled. Still popping the fuse. The second time, it popped, I saw a little puff of smoke, come out from under the dash. Any ideas what it can be and what is on this circuit? Any help in this matter is greatly appreciated. BTW, the truck is a 2002 crewcab.

Thanks,
Don Z.

:lol: That narrows it down :lol:

Look at the underside of the electrical center lid, or consult your owners manual for a location label. Each location has a name.

We have no way of knowing who has put what where in your fuse box. The color of the fuse is of no help.

The diagram on box lid says "Ignition" and there is only one 40 amp fuse in the truck.

Any additions to the electrical load? Added electrical equipment? Non stock systems?
IGN A or B?

No. The alarm was attached to it. But it has been removed.

Look for a bare wire where your alarm tied into the ignition wires at the steering column.

I am still looking. I need to get the ignition key housing off the steering column. Can this be done without removing the steering wheel? I have ruled out the red wire going to the ignition key. I think it's going to be a pink wire and it is up in that housing. I had the fuse pop on me, again and it was when I was using the tilt, this time.

The cover will come off without removing the steering wheel.

Yes!! The problen is solved. I was in the middle of the shifter console swap, when I found it. It was the pink wire, up in the column. It had the insulation rubbed through, from being to tight. Maybe, I use the tilt to much.

Thanks for the help,
