1985 County fog and reversing lights not working

Nathan P · 2025-07-30T12:29:44+0100

Hi,
I am new to the group. I have a 1985 County 110 and the rear fog and reversing lights don't work. The fog light warning light on the dashboard does not come on and there is no power to the switch. I can't work out which fuse to check but they all look okay. Please can someone tell me which one to check? Is there a relay for the fog light?
Is the reversing light connected to this problem or another problem?
Thanks

Pull all fuses one at a time and check.

Your fog light should only come on if you have your head lights on.(if you put high beam on the fog lights turn off)
And if you are on glass fuses make sure you get a reading on both sides. These holders are prone to not working.

Now if you want to quickly check the lights…
Remove rear cover where the cables come from the chassis into the rear tub, check the purple(live) has 12v…find the wire for fog/reverse and power each up for a second to check.

A multimeter is a constant toolbox companion. Strongly recommended.
So is a wiring diagram. I have an '87 110 and I'm still looking. Can find miliary wiring diagram, and rough copy/difficult to read civvy examples. If you find one, please share here.

These are very good and thank you.

Have you recreated them by chance? Would there be a PDF available that does not pixelate when zoomed in? At my age...my eyes need all the help possible...
