Hi all just purchased a 1982 1275cc mini, I think it is a rover and I have a problem....obviously, I've read other posts similar to my problem but I thought I would throw it out there. I was installing a HU/radio today and cutting wires, I cut the purple wire and the light green ACC wire, got a small spark, and now the light green wire is not hot when the key is switched to on, but the purple wire is still hot. Now my indicators don't flash or come on at all, my hazards stopped working and my interior light doesn't work.
I've checked all inline fuses I could see (approx 10 total, under the instrument cluster and under the bonnet, and the black fuse box under the bonnet) all are fine.

I've tried going over the wiring diagrams for my year model (if that's even correct), and I can't see any other inline fuses hiding.

I'm wondering if it could be a relay....or the hazard switch...or is there some other fuse location i'm missing? Any thoughts would be much appreciated.

I don't understand why you'd want to cut any wires

Where were the wires you cut? The indicators are supplied via the hazard switch light green/brown wire. Purple is for the horn & headlamp flasher - the supply to the hazards is purple/orange and shares an inline fuse with the interior light.

Use a circuit tester to test fuses, you can't always see if they're blown. Did you have the hazard switch out? You haven't put it back upside down? The light green brown wires go to the bottom.

Seems crazy to dive in there cutting wires! No wonder it doesn't work any more. Join them back up again - and check the fuses again.

There were only 3 wires that were cut to remove an old HU/radio plug, the purple, light green and the black. The new radio plug had to be connected and the only way was to cut. The radio is completely out of the equation now, not even hooked up, and all wires have been capped.

I have switched the flasher relay with a new one, that's not the problem, I assume, cause there was no change in the hazard lights, indicators, or interior light when tested.

I have left the hazard switch in it's original place, it has not been unplugged, EDITED: none of the wires are hot.

Where is the inline fuse for the purple "hot" wire? I have 4 inline fuses under the instrument cluster, and only 6 under the bonnet near the windscreen washer motor. Would it be in one of those locations? Since the purple/orange is hot when the hazard switch is in the off position I would assume it's not the inline fuse?

Also, is it possible a surge could take out the hazard switch, before it takes out some other fuse? I am going to test all my fuses and see if any are bad and not showing that they are blown.

Thanks again for all your help(s)

Try blowing some wd40 into the hazard switch - and switch it back and forth a few times. I have 'repaired' a hazard switch that way before now!

Ok, i've tested all inline fuses (10 of them) and the fuses in the fuse box under bonnet (4 of them), all are good.

CORRECTED: I have tested the hazard switch and no wires going to it are hot.
I have also tested all wires going to flasher relay and none of them are hot. Tested the light green, purple/orange, and the black (ground) just to be thorough.

I tested all wires going to interior light, none are hot.

Since this all started from a spark from the purple/orange and the green ACC wires going to a radio/HU could there be a fuse somewhere in the steering column for when the switch is switched to II position?

I have included some pics of the location of my inline fuses and the plug behind my hazard switch, maybe this helps.

Found another fuse under the 4 other inline fuses above the heater....this is the acc light green wire inline 5A fuse, switched it out and now when the ignition is switched to the II spot the light green wire going to the radio/HU is now hot. That's great, but i'm still trying to find out how to fix the hazards, indicators and interior light. The purple orange wire going to the Flasher relay is still not hot, and the light green, of course, is not as well. The interior light purple/orange wire is still not hot also.

Spending my time trying to trace through schematics but it's hard to determine what schematic to follow when you don't know the actual year of your car...

The cluster of wires you've circled above the switch panel is for the headlamps.

The fuse I think you're looking for is a line fuse under the bonnet with a brown & a purple/orange wire.

The radio is a light green wire, fuse under the dash

Tested fuses again, none were blown, so I cleaned the fuse contacts inside the white inline holder... on all of them, cleaned my relay contacts and my fuse box contacts under the bonnet. Even-though I had not played with these wires before I still went through the process. I now have my interior light hazards and indicators working....HOWEVER, now my instrument cluster lights (that turn on when you push you headlight switch to middle position or the bottom, on, position) do not work. With the key in the II position I've tried to check operation, I have noticed, also, that my rear right "parking" light is not on but the bulb is fine, and the red and brown wire inline fuse under the bonnet is very hot to the touch (just giving all the details i can). Any ideas on that one?

[rathesungod]

**SOLVED**
I pushed all my black connectors next to the steering column together, just in case any were the slight bit loose and that fixed the right side parking lights, and my instrument cluster lights.

When it comes to electrical problems, check fuses, then clean ALL contacts, with sandpaper or dremel tool, even the fuse box blade terminals, then tightly push together all connectors you can get access to.

Gotta love the prince of darkness.

Are the hazards and interior sorted aswell now?

The hazards and interior light use the same inline fuse. The indicators going aswell is abit of a mystery though.
There's two seperate circuits for hazards and indicators if you're using the original loom.
Did you check the indicator flasher underneath the dash aswell as the hazard flasher?
