So I've just discovered that the mini's lights aren't working. This includes everything except for the indicators, so headlights, dipped lights, reverse lights and brake lights all don't work. However, the rear lights stay on, although I can't tell if these are the brake lights stuck on or just the rear lights.

Any help is greatly appreciated!

Headlight switchs can sometimes burn out if you have halogens headlight fitted, have you checked all the fuses? what type of mini is it and what age?

It's a 1986 Mini City. They aren't halogens but the electronics and fuses all seem to be a bit of a spaghetti mess, I'll try and sort them and and then give you an update from there. Thank you!

As ever check the brown wires at the starter solenoid, then all the fuse box connections, don't forget to clean and vaseline everything you take apart.

So all the wires seem to be fine, nothing is corroded or disconnected.
The fuses are all fine too.
I haven't taken off the steering cowl yet but anything under there wouldn't affect the headlights and hazards would it?

Basically things that work are the indicators. The brake lights come on when the ignition and engine is on. They stay on too and pressing the brake doesn't affect them at all. The hazards, headlights, dipped lights, horn, dash lights, reverse light and fogs don't work at all. Completely stumped

Fuse box corrosion causes this

Thank you! I'll get a new fuse box and see if that sorts it out

Got to be a combination of corroded wires, terminals and fuse box.

I'll bet one or more of the spade terminals looks OK but it's rotten inside.

Would you say a new wiring loom is overkill? The mini's been plagued with electrical issues. I'll have another look and check and clean all the terminals and change the fuse box first though

Just a fresh set of terminals, fuse box and clean every connection from the battery to every item should be fine.

The fuse box connections were all quite loose and the mini is a flip front so I think that the headlights haven't got an earth. I would imagine that what you said is exactly what the mini needs. I will keep you updated
