Number late light wire burned out along its full length. Why??

Evening people.

Just a quick one. My 93' Cabby broke down for the first time in my 5 year ownership last week. Turned out it had blew a handful of fuses including the fuelpump. Replacing the fuel pump fuse just lead it to popping again straight away as soon as I disengaged the immobilisor to start it.

Anyway Ive had a look and the E1 wire from the fusebox all the way back to the number plate lights has burnt itself out mangling itself with a number of other wires along its route.

Now wirings not my strong point so can someone tell me why its done this. I'm 99% sure I didn't even have the lights on at the time. In fact I know I won't have as it was broad daylight.

It looks like i'll have to replace that whole E location harness but don't want it doing it again. I'd understand if it was the fuelpump wire or something else that draws a lot of current but not this.

Also since then the clifford concept 650 is playing up aswell so i'm assuming it must have melted through that also.

Any idea's, thoughts, opinions or experiences anyone??

Cheers,

Craig.

possibly e1 wire burnt out a while ago, and the damage has been lurking there waiting to strike? most likely cause would be a short to ground on the e/1 wire somewhere along its length, though why it didnt pop the fuse rather than melt i cant say, what fuse was in slot 20? should be a 10a

if you replace the E harness with a good replacement you should be good to go, I would also look at the clifford wiring to where and how its been spliced to the main loom as most alarm installers are cowboys from all of the work I have seen from them on looms I have repaired is anything to go by.

I assume the clifford is spliced into your boot light? if so check the wiring to that maybe it got damaged at the same time
