New style fuses?

I read somewhere on here that there are new style fuses available for 123's (and other MB's) that are better than the original ceramic type with silver strip. I checked mine out and if I move my CCU fuse much, it sparks and my CCU quits. I think I really need to replace all of my fuses. I did notice that one of them are the glass tube/metal type and is shaped like a torpedo like the ceramic fuses. Is that normal or has someone replaced it already? Also, where can I get this new style of fuse? Thanks!

I've seen them on ebay, but you might be able to find them at your rregular parts store. I think the copper ones have the best conductivity ( at least that's what I've heard).

I think the main thing is to replace them. Both the silver-colored type and the newer copper colored fuses seem to be resistant to corrosion, unlike the originals. Maybe that's just because they are 25 years old.... or maybe the old style really were straight copper, they really corrode badly.

The main advantage of the old style fuses is that they are color coded so you can tell at a glance what size each is. Additionally, it's easy to see burned out fuses. If your fuse panel cover fits tightly, you should not have corrosion problems even with copper. If the fuses get wet, they and the clips will corrode no matter what they're made of.

I don't know whether the silver-colored metal in some old-style fuses is aluminum or tinned copper. One of these days I'll take time to investigate.

Make sure the clips hold the fuses tightly. Old fuses can be cleaned up with fine sandpaper or steel wool and will work as well as new ones.
