Guys, recently ive been having a porblem with my remote starter. For months everything was working fine. The other day the main fuse blew after I hit the start button on the remote while the car was running and the keys were in the ign. I replaced the fuse and tried doing the same thing and it worked this time. Scince then when I use that function the fuse will blow randomly. I know the simple answer here is I have a bad connection somewhere but Ive looked at every wire and they all checked out ok. Any ideas here? The vehicle is a 95 ford f350 diesel.
Thanks
Steve

Well meter all your heavy gauge wires during remote start. See if any of the wires are grounding out..trace those wires and see whats going on. ------------- ~The Rookie~

the only i can think is because the car is diesel everytime that you do r/s while the car is running it shuld pop the fuse because the brain has a wire that works with the wait to start, so the brain try to wait to start but it doesn't see it the wait to start signal.

Ummm..... noooo. Not even close.
It popped the fuse simply because it is a diesel. A diesel will draw more current during remote start, especially when it is cold out due to glow plugs, intake heaters, or whatever other method they use to initiate combustion (there are no spark plugs.... diesels use compression ignition). They also draw a lot more when cranking due to the higher compression. It really isn't unusual for a diesel to pop the odd fuse once in a while, especially when cold.
Steve:
Pull apart the XCRS (relay satellite) and have a good look at the soldering inside to make sure it is all in good shape. A slightly intermittant or poor connection will draw more current.....

one of our old shop vans had the same problem... after verifying there were no shorts anywhere and all wiring was good i bumped up the fuse on that leg to a 40 amp and never had a problem again... as Gus said sometimes it's just a matter of natural current draw......
