As some long term members know, I have replaced the dogbones on my LTD with regular ATO type fuse holders. Problem is, that they only last about a year or so, before they show signs of problems, as in the main fuse melts on one side, with associated corrosion in the holder. Does anyone know if there is a heavier duty unit than what is normally available at your local auto parts house? I would prefer one with heavier gauge wiring that may last better. These bikes have a huge electrical load on the primary side, so when the main fuse goes, it isnt pretty.

Thats what I have been doing and am still having issues with the heat on the solenoid side of the fuse, it doesnt seem to be a current issue, as the fuse doesnt blow till the housing melts, but it sure is acting "odd". Ill see if i can get some pics here of it. or if i canned the bad fuse



OK, here are some pics of the fuse, the holder, and post-mortem inside the holder. This thing is burned up good, the fuse is showing signs of heat damage after a whopping 10 miles of use. there are no other signs of problems with the electrical system, so I am tempted to say that it was a bad connection at the fuse block. Problem is, that this is the strongest rated block that I can get locally, and it isnt the first one that fails in the exact same manner.

I used to have it wired across there, until I had another wiring problem. now it attaches to the terminal where the battery cable goes (top of the solenoid) but corrosion is not an issue there.

ok, I have once again, replaced the holder. Its a unit from Littelfuse (brand from Checkers here in the USA) this one has a cap over the fuse, but i dont think that was the underlying issue with the old one ( we dont get much moisture here in AZ to cause corrosion like what was seen here) My personal feelings are that they are made to just barely handle the load, and not much else. I will be looking into getting a better fuse setup for the bike, as this one has almost left me walking today (good thing the EFI runs on a separate 30 amp fuse ( and no signs of problems with this circuit either EVER)

I had read the other thread, Mike. I will inspect the one on my 1983 and see if it is burned, been hot, or corroded in the socket. Could be some 30 amp fuse holders are not made well, I guess. I did burn some wiring last fall in the fan circuits but did not affect the 30 amp fuse or fuse holder.
I would like to know exactly how ScottInNV has his connections made.

connections are all soldered in for the fuse holder, with the standard ring terminal connecting to the battery side of the soleniod. All wires are 10 ga or better throughout the charging circuits. I work as an electronics technician, so I know the value of a good soldered joint as opposed to a crimped in connection. No other sites in the wiring show issues, just this one side of the fuse holder. that is what has piqued my curiosity

That is the style that I have in there now on teh main fuse, and also what I have on the 30 amp EFI fuse. I will keep the board updated on the "robustness" of this one.

Sorry Scott, for getting more detailed than you needed. A lot of members are not experienced with schematicsor electronics.
I am at a loss on your problem. Would like to know if the new one works out over time.
If you are making some trips you might want tocarry a spare made up just in case.
Sorry we couldn't come up with better information.:baffled:

Not a problem, I can appreciate that, I was mostly interested if others had issues with poor quality fuse holders as well.

Yep, same thing mine did, ran like crap, but still kept going
