Engine Bay Fuse Box..

[marcostig]

Just changed fuse box in engine bay as 2 largest cables were loose and had slightly melted fuse lid..now the 2nd one down is very hot, 110amp one belive goes to main box in car?.have other galaxy owners had a problem same as, any way to rectify it or just left it alone?? had car 7 months now always been hot should i be concerned or not is it common?Lid has a samll melt mark where the metal crimp is.Any advise would be nice thanks.

The problem is the cable not the fuse box. The crimp is faulty and getting hot. Known and common fault. New cable required.

if it is the second cable down, you dont have any real options other than to cut as far down the heat damaged cable as is possible (normally 2-3" is enough).

 

You then need to get a new Battery Junction box from your Ford/VW/Seat dealership (they are about 20-22GBP and come will a new battery cable and fuses). You also need about 3-4" of 16mm2 super flexible welding cable, 16mm2 butt crimp, and a 16-10 crimp eyelet.

 

The costliest item needed is the crimp tool to crimp on the butt crimp and crimp eyelet.

 

6" of heatshrink will finish the job nicely.

 

I had to do mine this year, about 3 hrs before I went to France on hols.

 

If you are close to Gloucester I may be able to help

ok brother in law an electician..so no probs in sorting it out then..so 3 or 4" should be enough then??

Try and remove any burnt/charred insulation, you should see when you find decent copper (bright shiny no dull/darker colour)

 

If you can't salvage enough clean copper, pickle the end of the copper in a mild acidic solution (lemon juice?), tarnished copper doesn't conduct very well, causing a high resistance and therefore hot spots.

 

Make sure you B-i-L uses good quality crimps and crimp tool, not the crap that Fraud/VW/Seat use. I can recommend Wilts if they have an outlet in your area.

It's generally better to crimp the terminal on to freshly fluxed copper then run solder into the whole crimped assembly as well to remove any electrical resistance remaining, this constitutes a permanent repair.

Thanks for replys going to try to do it this week hope it will sort it out..

[sparky1000]

get the battery checked as well this happened to me and it was down to the battery dropping a cell so the alternator was working overtime and damaged the fuse box.New battery new fuse box (

[marcostig]

batt was replaced this year..will still check though..

[marcostig]

all done!! cable end was burnt/overheated, cut back 3 " new crimp butt crimp heat shrink nice and cool sorted 16 amps going through so no other probs..apart from an oil leak on power steering hose doh! getting there in the end..

[sepulchrave]

Get the power steering hose repaired at a hydraulic engineers, it'll cost you a small fraction of a dealer replacement but you'll need to remove it first and take it to them.
