Hot Fuse Box

[neils]

Hi,

 

Just had a few weird electrical problems and thanks to this forum have traced it to the common melting fuse box problem.

 

The alternator to fuse box cable is getting very hot but the box itself hasn't started melting yet. Could I get away with getting the cable cut and a new end put on by an auto electrician? The fuse box looks ok.

 

Thanks....

have you checked connections are clean and tight? - could be caused by high resistance at cable ends

That is NOT the solution. This is a common fault and the heat is generated by a faulty crimp. The only way to repair is to either recrimp (with new crimps of course) the ends of the cable, or solder on new crimps, or get a new cable complete.

 

If reusing the old cable, you must cut off the end until you get back to unoxidised copper. Also a damaged fusebox is best replaced.
