After two years of rebuilding the engine and getting it running my city e is on the final stretch to getting it's MOT but I'm a little stumped with the electrics

When I was putting the dash back in with the switches I broke the hazard switch which meant I couldn't turn it off

Just bought a new one from minispares but nothing is working

At the moment I have no indicators or hazards. My rear screen heater switch isn't lighting up, the screen itself has never worked but the switch did. I also have no light on the brake pressure warning despite that being in the whole time until I had bleed the brakes etc

I also have no horn (insert rude comment here)

I also have a distinct lack of knowledge but I do have a multimeter, I think the phrase is 'all the gear, no idea!'

Can anyone give me an idea on where to start?

Check the fuse box - horn, headlight flasher and brake failure circuit are all on the same fuse. If the fuse is not blown, check for corrosion on the terminals and the fuse clips. I had this problem in my Cooper, with intermittent failures traced to corroded fuse box, replaced with a new one and all the problems went away. Not a difficult job to do and I didn't use my multimeter either :)

Actually I'm wondering if I blew a fuse by wiring in the switch wrong. The white connected is obvious but there are two wires that attach to the sides of the switch and I could've put them the wrong way. Which colour goes in which side as you look at them?

Here's where I'm up to:

Tested all the fuses and they all seem fine, unless I'm missing something I have 8 in total? 4 in the fuse box and 4 inline, am I missing any.

Although they weren't blown they did seem to be a little corroded so I've lightly sanded the end of each fuse and I have indicators back and hazards. Now the hazard switch doesn't have the two side wires connected as I'm a bit nervous until I know which way they go!

I have no horn or headlights but my interior light has come back

Where do I go next?

The connections on the sides of the switches are just for the lamps in them. Polarity doesn't matter unless you have put LEDs in them.

Check the stalk switch connections.

Ah ok, thanks for that, will connect them back up tomorrow then

The stalk seems ok for the indicators but not the horn

Headlights, I have a feeling that's a corroded bullet connector again

Ok here's where I'm up to but I still need help

I checked all the fuses and they all seemed ok, nothing blown, so I checked all the connections and have them a rub with sandpaper

I also did the same for all the bullet connection at the front

I have taken the steering cowling off and checked the connections and we seem ok there too

I have got back: hazards, indicator, interior light and rear screen heater

I briefly had the brake pressure test light back but that's now gone again. I also have no horn and no headlights

The stalk that the horn is on has always been a slight issue, the flash has never worked but everything else did

Is there a way I can check the stalk itself? The indicators work on it but can I check that the switch for the horn press is ok and can I check that the headlight switch is working?

Mine has 3 (or 4?) in line fuses just above the steering column and above the brake pedal.

My dip beam headlights went and I found one of those fuses quite badly burned and partially melted. Replaced the in line unit and had lights.

The glass fuse looked OK, ie: wire intact, but the fuse was knacked when tested for continuity.

 

Still trying to find out why it got so hot, but don't go out much in the dark!

All of the fuses, in the box and the inline fuses have been tested with a multimeter. Beg hinting to wish it was that as it would be simple lol
