Distribution block fuse melted but didn't blow?? Help
Tuesday, May 08, 2007 9:35 PM
Hey,
I've got my MRD-M1005 powered by an 0 ga ran to a fused distribution block and then to 4 ga to the amp.

I was listening to some music and the bass would cut out for a couple seconds and then come back on so I had no idea what was going on. I went and looked at the amp and it said like 11.4 volts and then a couple seconds later said 13.8.

I didn't know what it was but today I was looking some more and the plastic of the fuse on the distro block is all melted but the fuse didn't blow.

Does anyone know what it could be???

I called my local shop and they said to check my ground and to do the Big 3 (which I plan on doing). Will this solve my problems or is there something else I need to look at.

If you need any more info, let me know.
Any help is appreciated.
Thanks

-Seth

Heat is caused by 2 things - a loose connection, or too small of a wire. I'm guessing the first.

K, I'll try that.
When I pulled my ground off my other amp and put the new one, I remember seeing a little rust but not thinking anything of it. I might have to grind some more off to get a cleaner connection.
Also, about a week ago, I was washing my car and long story short i got water on the amp. It didn't work for about a day but i went after it with a towel and a can of compressed air. Would this water have done anything to make this problem happen??

no, but you shouldn't see any oxidation on your wire. oxidation is caused by a bad connection heating up.

You should be able to see where the plastic melted and then where there are scorch marks on the metal.

I resanded my ground and screwed it down really good and put a new fuse in it. It's working but we'll see what happens.

I think you took something wrong. Your ground having a bad connection wouldn't cause your fuse to melt. A bad connection AT THE FUSE would cause your fuse to melt.

lol
I thought something sounded wrong when I was doing it, lol.
Well I checked the connection at the fuse and everything looked fine there too so idk what it would be.

Could a hot amp cause that to happen?? I had a couple t-shirts over the amp because I was getting water thru the trunk and I would imagine the amp got pretty hot.
Also, I was thinking maybe it was from too small of a fuse but then decided it wasn't that because the plastic melted and not the fuse part.

dont be so certain the fuse didnt blow and melt itself back together again. I've seen that happen.

Hmm, that coulda happened. Only thing is that the fuse woulda had to melt under where the melted plastic iss where i couldn't see it (i would think).
I'll keep an eye on it and see what it does.

it could also possibly be a defective fuse, the actual fuse didnt blow, but it did turn black, so i would probably say bad fuse from start, not to mention, you can tell you had a good connection on the fuse because of the marks that are on it from the screw.


many changes in the making
