bx wiring

[robin hughes]

Hi All,

I took the handbrake surround out yesterday to renew the handbrake cables. not a problem there! but on re-fitting the surround i put the rear elctric switches back in the consul and tested them. When i use both left and right rear window switches up or down? the switch starts to smell of burning why is this???? All i did was take the consul out, disconnect the rear window switch wiring do the handbrake cable then refit the lot? I HATE french electrics

sounds like you have a short in there matey! whp the casing off and check the wiring through for dmamge! also check the switches work with the casing of! then make sure hte wiring is away from all the screw holes when you put it all back! i have done it several times! best one being putting a nail through the wire that powered the bathroom heater when we were rebuilding the house!! felt stupid when i foudn it was my mistake a yearon loL!

i suppose id better take it back out then but on re-fitting i double checked id not screwed through the wires as i pushed them away. I dont realy feel like taking it out again but i dont want my car to set alight?? as i dont trust french electrics.

All wiring is ok and free from obstruction. But the problem is still there. Its the same on both rear window switches.

hi there usually means the plugs aren´t in right or are the wrong way round.

rob, i wouldnt keep a bx vs you score as its going to end up like a very one sided Rugby match matey loL! BX 147 Robin 14! haha! you know it because its french!

its prolly something defyingly simple thats causing it! you'll kick yourself when you find it too!

the times i have completely rewired something to find out it made no difference loL!

I would not bother removing the console just whip the switches out and pull some wire through as well then you can check the wires for any sign os damage and then test the circuit by operating the switches and check that it is actually the switch that is giving the smell, it may even just be that the switches are dirty and through lack of use are burnibg off nay crud that has built up.
Give them a shot of contact cleaner of WD-40 and give them a good work out with the power off before tryinmg them again.

Also worth cleaning the plug and switch contacts as well to rule out anycrud being burnt off.

So long as the windows appear to be working freely there really should be no need to worry.

I havent ever checked the rear window switches, but if I recall correctly the central locking is positive earth or something daft - I had fun getting a Sparktronic alarm fitted to my second BX many years ago because the central locking worked back to front compared to sane cars.

Best bet is to check things out with a multimeter, twice, then stand by with a fire extinguisher and a handful of spare fuses!
