MG MGF Technical - REVERSE LIGHTS

I have no longer got reverse lights,the fuse is ok,bulbs are ok!Thinking about it they may well have stopped working when I fitted the K&N filter conversion,could I have knocked a wire off the rev switch ? is it in that area?
Any one done this?
Thanks in advance

Kev,

Very odd IMO. AFAIK there is no wiring in the area of the K+N that relates to the reversing lights. Sounds very much like a fuse to me, i know you said you have checked them but did you check BOTH fuse boxes? And do the reversing lights apear to be an isolated problem?

Fuse box under steering wheel.

Kev,

If the fuse (Fuse 16) has gone to your reverse lights then your brake lights will not work either! Check your brake lights. If OK then problem could lie in the switch on the gearbox or the harness to the rear light clusters.

Sorry Kev,

Not sure where the reverse switch is. Perhaps Dieter K could help?

Kev,

Wiring diagram shows the supply for the reverse light coming from one side of the brake light switch. Perhaps you could check that the wire which goes off to the reverse light circuit has not been pulled off leaving only the brake lights connected. The two wires are both coloured green/yellow. Long shot!

Reversing light switches are often found screwed into the gearbox.
Generally they are plunger operated mechanically when reverse gear is selected.
Should show on a workshop manual.
I'm afraid my F is not avilable for me to check right now.

Nobody else an idea ?

My workshop manual shows a cable snaking up from gearbox just below where you've attached the K&N.
It couples into the main harness via two separate torpedo like connectors just near the distributor cap.
I'd be very surprised if they were loose but it's worth a check.
The switch itself is screwed up into the gbox underneath the car, connecting wires emerge directly from the switch and run up to aforementioned connectors.

Hope this helps

Kev C. I just changed my reverse light switch this afternoon. Get to it from under the car, right side on the gearbox. You will find two switches there, follow the wires and choose the lower switch. The job is less than 5 minutes. I picked up my new switch from British V. and it works just fine. Don't worry about getting the leads wrong, you can't. The switch is a push on switch and I believe the grounding is right at the lights. Happy driving
