Melting Fuse box

[tiny84]

Ok so my fuse box on my 84 appears to be melting I'm starting to have loose connections in the fuse box causing it to blow fuses and have weak connections for the electrical system. I sometimes have to wiggle the ignition fuse to get the bike to start. any one run into this? if so what did you do to remedy this issue?

I had a similar situation and what I did was went to the local auto store and bought a fuse holder that held 5 fuses and replaced the original. I was roughly the same size. It was less that $10.

I took my time and soldered all of the connections. It worked out very well.

Be sure and save the fuse label or what I did was tape a label to the top of my air box with the fuse names, locations, and sizes on it for future reference.

 

Good luck,

Steve

kinda what i figured just wanted to know if its something on the bike causing it or if its just common. I had one of the fuse holders finnaly snap last night on my way home but i keep pieces of wire with gator clips on em so i could bypass the fuse on that one so i could get it home

I'd say that it's just old and worn out.

Clips get weak and break, etc.

In fact when I replaced mine, I bent some of the still unbroken clips and they fractured very easily.

Tiny,

 

Here's what I did when my '84 crapped out. It's an 8 spot holder that uses spade type fuses. I bought it from my local electrical supply house, if you can't find one, I do have one here at the house that I could sell you.

it sounds like an update to the fuse system on my bike is probly in order just as well since i never like those glass tube fuses myself time to upgrade to something a lil more modern

This is the way to go Squidley has a nice set up. I just did this to my bike when my ears were breaking.

Here is a pic of my replacement fuse block

It is a pair of Littlefuse part #03500417XP's ganged together and has been in service for a year or two now. Gives me lots of space for extra fuses as I add stuff. Sits neatly on top of the battery and is just tall enough to touch the inside of the cover which helps to hold it in place.

 

Hope this is useful.

Before you go to the troule of switching out the fuse block, I would recommend finding out why the old block is melting.

 

Sounds like you may have a high resistance draw somewhere that is generting enough heat to melt the fuse block. If you do, Simply changing out the block may not correct the problem.

 

Just my .02 cents worth on this one.

Good point, but I bet the resistance is right there at the fuse clips. They are weak and brittle as has been noted, and tend not to grip tightly. Mix in a little 20+-year-old corrosion and you get high resistance. I've experienced this on two 87 Yammy's.

ok well part of it is probly my own fault i've been running without the stock airbox for a bit now and it gets a lil more heat up there. put the stock box back in again, but again none of the fuses are held all that securely they seem to rattle around a bit and if the bike wouldn't start i'd just press on the top of the fuse box slightly and it would start right back up. I tried to tighten the contacts but the just snapped off. I have to replace the fuse box anyway now. the excess heat seems to be due to the "loose" connection of the fuses in the fuse box none of the wire gets above ambient temp aside from right at the fuse box.
