Those were good batterys, my friends 2002 Harley F150 still has the stock battery.

 

Figured out that the Ignition switch fuse was tripped........ Replaced the fuse and it blew again!!! Reasons why???

 

short somewhere. I'll see if I can trace the wire on my alldata account if the baby lets me that is.

If the fuse is F2.101 change the starter relay. If that fuse that is blow is F2.102 check the other fuses like F2.01, F2.07. F2.13 if they are all good I'd change the ignition switch. probably shorted internally. That ignition fuse delivers power from the junction box to the ignition via a LG/VT wire it's a pretty heavy wire around 12 gauge. That could be shorted if you recently did some work behind the dash.

 

where exactly would I look for the short? Not sure where to even start.

 

Sorry I got the fuses mixed up hard to look at more than one diagram at a time. Give me a sec.

 

ok here's a link to the diagram you need.


I'd bank on the ignition switch being toast. I'd probably test it by putting a multimeter lead into that fuse holder on the switch side and the other lead on ground with the meter set to continuity check/ohms then cycle the ignition. If the meter zeros out on the ohms or beeps then the switch would be shorted internally. You might pay attention for what position it's in when it indicates a short. But more than likely it's the switch.

I added the testing procedures to that album.

 

So lets say that the switch has gone bad and I change the ignition switch..... Do I need to take the truck to the dealer due to the PAT system for a reprogram?

Well I'm not %100 certain but I think you will. I did find this post about the PATS and ignition change on a focus. This guy did a work around where he taped the original key to the antitheft box till he got around to getting the keys programed.

edit: if I'm remembering right there is something in our owners manual about programming new keys. You might be able to fool the system by doing the steps with one of the orginal keys taped on the side of the steering column near the ignition switch. I've never changed the ignition but on my old thunderbird and that was pretty easy. From what I seen it don't look too hard. hopefully someone else can post some information. You may want to start a new thread or PM rockpick to change the thread title to something like ignition bad help!

 

Good idea thanks for your help!!
