Fuses?

[2edgesword]

My front jack fuse was look a little discolored so I figured it would be a good time to replace it. I got the same size 30A fuses, put one in and no power to the jack, not even to turn the light on. I put the old fuse in and everything works. Put the new fuse in and no go. I checked continuity on both fuses and both are good? What am I missing?

Well what appeared to be fuses of the same length proved to be inaccurate. The new fuses is about 0.7mm shorter so the electrical contacts in the fuse holder were not making contact. I added about a 1mm thick folded up strip of aluminum foil to the cap and now the contacts are making contact with the fuse. Actually I’ll probably file down the cap so it will screw down further and not stop before the contact in the cap makes contact with the fuse.

That discoloration on the end of the fuse appears to be rust not heat discoloration. Your fuse holder may be leaking water, which will eventually damage the holder.

If your fuse holder is the same as came on my Hummingbird it wasn't made to be exposed to weather. Mine developed some severe rust so I went to a marine store and bought a waterproof holder and put it on. The biggest problem was getting the wire through the holes.

I would swap out that "old style" fuse holder for a blade type fuse version (ATC). Just pop in a 30 amp fuse in a heavy duty holder and that should eliminate future problems.
