Blown fuse in X50 power cord:(

**intregrah** · 01-31-2007, 01:14 AM

Hey guys,

So yeah I've got a blown fuse in my smart cord, (definitely blown I've checked it with a multimeter) I was wondering if anyone knows where I could buy a replacement? I can't believe how hard Escort has made this by wiring in the fuse to circuit board so it can't be simply replaced, but Im determined not to cough up the cash for a whole new power cord, especially seeing im in Australia, so does anyone know of any place that sells fuses that can be wired into circuit boards?

Cheers for any help

I went to the autoparts store and bought a glass fuse. It's is bigger, but just fits. Just heat up the ends of the glass fuse and solder wires to it. Use solder iron to remove the old fuse. Solder in the wires you attached ot the new fuse into the circuit board. No big deal.

I thought you had to just replace the whole power cord?

well i am not sure what caused my issue with the smart cord but Radar Roy has allready fixed it by sending me a new Cord.

Thanks Radar Roy for your Great Service

Hey Chris,

How big is the glass fuse? Ive got some 20 mm ones but i dont see how they could fit. My fuse is parrallel to the line of leads coming off the circuit board, and right next to them, so I cant see how i'd fit it there... Can you tell me a bit more about where u put it?

Cheers

One other thing, does anyone know anything else about the fuse used here? I was hoping someone might have a copy of some sort of electronic schematic manual for the X50 (if such a thing exists?). Just wondering if anyone can tell me any other specs for it seeing apparently theres a lot of other attributes a fuse has besides just the the 2amp rating.

cheers

Fuses are rated in both Voltage and Current as well as how fast the fuse will open when in an overcurrent situation. The simple answer to the Smart cord fuse is to use the fuse or a similar fuse that I posted earlier.
The Smart cord fuse is almost certainly 125V, 2A Fast-acting fuse. The "Fast-acting " just means that if, in the case of the Littlefuse #0251 002, the current is exceeded by 200% the fuse will open in about 1 second or less. For fix-it yourself-ers, be careful to use a FAST acting fuse and NOT a SLO-BLOW. A Slo-blow fuse can withstand an overcurrent situation for much longer, perhaps long enough to cause irreperable damage to your detector. 125V, 2A Fast acting is what you want to use.

Hey, wow thanks insider somehow I missd your original post with the exact info I was looking for. But just one other thing, on the littlefuse site, after finding the part number and clicking on add to cart, theres about 30 different variations of this particular fuse. They are all referenced eg: 0251002.MAT1L, 0251002.MXL . You don't happen to know the exact one we need do ya? Thanks heaps!
