Trying to figure out what I have going on here. Will bad glow plug/plugs cause the 175amp fuse to blow everytime you turn the truck on and throw a ses ligh when cold? I get a p0380 and a p0540 code and tried a different glow plug controller but no luck. I haven't checked my glow plugs yet but will. Last thing I have is the glow plugs but just wondered if thats my culprit for the fuse to keep blowing. Can't find any bare wires that I can see and like I said tried another controller but the same thing keep happening. Any help would be appreciated. Thanks!
