blowing fuses

[stroker]

my fass pump fuse keeps blowing. I have checked the wiring everything looks fine. Wondering if fass pump is going out. Doesnt blow with 30 amp fuse. I know a bigger fuse is not the answer but it kills me to not have my system working because i look at my diesel gauge droping and feel my wallet getting thinner.

For what it's worth, when a device requires more amperage than usual to operate, generally there is a source of more resistance. Sometimes it can be normal, or a non-issue in the long run, or it can be a sign of eventual failure of the device. I guess this doesn't really help at all, but check wiring for possible short spots, possibly where wire is exposed, or has had an outer wire cover striped( with strippers or a knife), where the strippers actually cut into inner wire cover of both a positive & negative wire at same spot, resulting in a short with wire movement. OR check for loose connections. Otherwise if you are blowing the 30 amp fuses, not from the result of an accidental short, the pump may need to be replaced, BUT it is usually something simple!

Stroker, as Capt suggested, check out the wiring. Not only the harnesses, but also the card under the dash. While I understand where you're coming from with the 30 amp fuse, I'd probably have to forego using the system until it operated with the specified amperage fuse. Easier to fix the problem than to risk burning up wiring and possibly the truck!

Have you talked to Jason or James on this?

Hey stroker does it still rain every afternoon in FLA? If so remember the three H's thats heat+humidity=headache.I lived in fort myers in my youth,Used to do car Audio(alot of Subs,amps,crossovers,etc,etc).I worked at a place called "beach Beatz" in Cape Coral in the early 90's.I had a long background in Audio,but when i moved down there i discovered a Quark,Always blew fuses(big expensive ones).This is what it turned out to be, Humidity causes condensation(water),heat in FLA 85-90 this time of year,water "weeps" into electrical componants.Trying dielectrical spray or grease or even "navy grease" before you tear that purdy piece of aluminum,sometimes its the little things..grease out

Stroker,
Any success figuring out what was causing your pump to be blowing fuses? - Patrick
