F450 Blowing Fuses - Common?


LawnSite Member
We have a 99 F450 that will blow a fuse when you put the truck into the drive gear. It doesn't do this when you shift to reverse or neutral but when it hits drive it will blow a fuse and I'll loose by throttle - the truck will still move, but only what it can at idle - it will not rev up. The truck does not blow this fuse every time, however it does blow it often.

Does anyone else have this problem or have any solutions? Thanks. :usflag:

you should check the two wires to the TCS on the shifter stalk. At higher miles, the wires may chafe and/or break on the top of the steering column where they make a right angle bend coming out of the hollow shifter. This can cause a momentary short to ground when moving the lever. Access for inspection by removing the upper column trim.
