Rigo Posted October 24, 2009 Report Posted October 24, 2009 The fuse holder under my hood keeps melting. Checked all the wires and there are no cuts or nothing to ground it out. Its the 1 run of 1/0 going to the rear red top under my seat. What could be causing this? "Da 2tone HOE from the 520"
Rigo Posted October 24, 2009 Author Report Posted October 24, 2009 it had a 150 amp fuse, but the fuse is fine it didnt blow or nothing! "Da 2tone HOE from the 520"
P4killer_ Posted October 24, 2009 Report Posted October 24, 2009 ummm make sure your bat under the seat isnt shorting out, if the fuse isnt blowing, its either heat issues, shorting issues, or just a cheap fuse holder.

Rigo Posted October 24, 2009 Author Report Posted October 24, 2009 I checked the rear batt twice and nothing can touch the post or anything. It looks really burned on the wire but only the side that goes in to the fuse holder from the front batt. "Da 2tone HOE from the 520"
audiofanaticz Posted October 24, 2009 Report Posted October 24, 2009 What style fuse and fuse holder are you using? What are your rear battateries grounded too? What kind of amp(s) are you running? Check to make sure there is no corrosion on your batteries where the wire is attached too, and no you can not look at it and say it looks good you have to disconnect your power wire from the battery and check the terminals. Clean it off if it looks corroded and re attach your wire. My next suggustion is to make sure your connections at the fuse holder are tight. Make sure that the wire is in the terminal tight, make sure that the fuse is in the holder tight. Even if its a tiny bit loose its enough to cause major resistance caused by only a small amount of metal to contact each other and with all the current going thru a smaller connection it will cause heat. If there is no corrosion, and all connections are tight for your powerwire and on your fuse holders, my next guess will be a bad/loose ground on your batteries. Make sure all grounds are grounded to a thicker metal with no paint so you have a metal on metal contact. If all that is good, Im going to have to say you are drawing too much current thru the fuse and holder. Just because you have a 150amp fuse dont mean it will blow if you exceed 150 amps of current. Many times a fuse will handle a bit more current then what its rated at! If your drawing a good 180amps of power it may not be enough to blow the fuse, but it will be enough to heat the fuse up more then it can handle. Depending on what type of fuse holder and fuse you have may need to be upgraded to something better such as a ANL fuse and holder which is better then the midi, agu(glass fuses), atc, and maxi type fuses. http://www.sonicelectronix.com/cat_i225_fuses.html Generally a melting fuse is caused by too small of fusing, or a poor connection at the fuse holder.
