Fuse completely melted?

[22mountaineer 10+ year member]

I sold a friend of mine a Jugg and mmats 1400.2 about a year ago..

Its been running strong and all the sudden the it quit working and he looked under the hood and the case just completely melted.. and melted about 2 inches of the wire on the amp side..

What would be a way to point out the problem, or more questions to ask him, this has never happened to me

power supply probably took a piss on it, pulled more current than normal then POOF!

arching @ the fuse holder, get a new fuse holder.

I guess im assuming the amp is no longer working, but then again you never said it was or wasnt.

Sorry it took so long, the amp does still work.

Are my eyes messed up or does that chick in the avy have 4 eyes?

Could the size of the fuse he was using be a reason? IDK what size it was and he deff cant tell now..

What size should I use for 1400rms? 100-150?

*not the reason it did what it did but maybe the reason it completely melted rather than just blow it?

arching causes heat.

arching can cause a fire.

replace wire, and fuse holder. make sure all connections are solid and tight.

make sure you have no shorts anywhere. Look places like firewall, is there a gromet there to prevent it from cutting through?

If he replaced the size of the fuse it could have caused it. If he required a 100 amp fuse, and used like a 200, could cause the wire to burn. Fuse is more to protect the wire itself than the actual amps and whatnot.

I will check these things, what size should he use on 1.4k

fuse by front battery should be fused at the max current draw on the wire awg, u then fuse the amp with appropriate fuse for it at the amp. So like a 300 amp inder the hood and a 120-140 amp inline to amp.

I've never fused anything in series with the amps //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif ......thats what the fuses in the actual amp are for. guess it couldn't hurt, tho I suppose.

its the fuse block man. seen this happen personally too many times. fuse blocks are made wayy to cheaply.

if you can figure out a way to to use ring terminals on the fuse block rather than shove wire in that hole and screw it down. solder the terminal to the wire for the best connection.

I still fuse inline even if amp has built in fuses, you are supposed to fuse each end of a run of power wire. If there was a short in the trunk it would have to travel to the hood to pop fuse, and extra protection for amp(s)
