Right,

This is pi$$ing me right off now. My hazards work, my lights work, my rear indicators work, my brake lights work, my interior light works, my dash works,

SO why for the love of zombie jebus do my front indicators not work!

I can figure it out. My rear light works fine (bar not flashing) but I cannot get any power to the front indicators. The fuses are all fine but it just won't work.

Any clues people? Or at least the correct wire map page in haynes for an 82 mini loom.

You do know it is a separate flasher unit for the indicators from the hazards, yes?

[Big_Adam]

Yepper, no idea if it work right. The hazard one does, the indicator one at least has power. I know that much.

[Jammy]

You have checked the earths for the front?

[mkw]

checked the bulbs lol

[dklawson]

Big_Adam, only you are going to be able to sort out the hybrid wiring you're working on. I'll try and help but check a couple of things for me.

I started writing a lengthy reply and then thought better of it. Please start by downloading and saving copies of the following two PDFs.
http://www.advanceautowire.com/mgb.pdf
http://www.advanceau....com/tr2506.pdf

These documents contain compilations of Lucas wiring diagrams for Triumph TR6 and MGB/MGC. Lucas did not change color codes much between makes/models so even though these aren't Mini diagrams they will be good references.

It was stated above that you are using a two flasher system. In earlier posts you said you were using 2-prong flasher units. Please confirm what arrangement you're trying to make work and what components you have. Lucas made both single flasher and separate hazard & turn signal flasher wiring arrangements.

The hazards are supposed to use the same lamps/bulbs as are used for the turn signals. Are you sure this is what you've connected, particularly in the front?

I had a problem with the indicators before, it's a totally different problem to yours, the flasher unit kept blowing.

Even if it doesn't solve the problem you might be worth upgrading the flasher unit to one of the newer versions which has 3 prongs - the two normal ones and an earth wire.

You mean that big screw/bolt on the driver side of the engine bay, right?

Well the front loom is just an 82 front loom. So not so much of a mishmash. Tar for the links too.

Right, the flasher is a two pronged one behind the clocks on the dash (82 clocks, wiring, colum, basically think of the wiring as on El Gordo). Then mounted on the bulkhead is another two pronged flasher for the hazard lights (connected to a green/pink and a orange/purple wire). The indicator flasher is connected via one green and .... think it's orange wire on the other prong are two meaty looking green wires. Each side reads 12v (or there abouts). I have no as yet tried the front lights with the hazards (would have been a stonking idea if I did that earlier ).

I check the bulbs all works (boardem and brain pains so I thought I'd try then out.). Every thing else seem to work so far, all the dash lights work, oil presser sender works (well, the wiring dose. The sender is FUBAR) Fuses are all fine (I'm adding as much detail so I may prattle on). Think my heated rear screen and fog light switch are bugged. Indicator controls work fine.

I can get pictures if that helps? But it would be tomorrow.

How have you connected the Hornet lamps into the '82 loom? Have you sorted an earth for them? The Hornet side/indicator lamp units are designed to be directly earthed to the body while the '82 indicators are earthed through the loom, you haven't got that confused have you?

[Big_Adam]

No, I just get no power to the wire their mean to use. Left (or right) uses a green and white wire, right (or left) uses green and red.

Both have no power.

I've been using the "check wire map, turn on bit I think wire is connected to and check for power" method of working.

Well if the front indicators are working it suggests the lamp unit is earthed, I guess?

Needless to say, try touching a wire against the lamp body and an earth point to see if that does anything.

[dklawson]

Big_Adam, if you can post pictures that may help. What would be of more help to me is if you can scan the wiring diagram for the '82 harness and email that to me or post it here.

If the color codes you posted above are standard for an '82 Mini... they certainly do appear to have diverged from the late BL products that were reaching the U.S. Therefore... your late wiring diagram and color codes will be very helpful.

[Big_Adam]

Okay,

I tried the wires on hazards and again no power to the green and white.

Also which diagram is the right on in the haynes. Is it wiring diagram 10 Mini 850 Saloon, Van and Pickup?

[dklawson]

Big_Adam, the green/white should be feeding the Right-Side turn signal lamps (front and rear). These lamps also operate when the hazard switch in engaged. The only time you should find power on that/those wires is when the turn signal or hazard light switches are "on".

I'm sorry, I can't tell you what diagram is correct. You've got a later harness and later manuals than I am familiar with. Only you will be able to answer what is correct since you're mixing parts.

[Jammy]

I have a funny feeling this might be the classic hazard switch buggering everything up again. Try wrapping a peice of un-insulated wire around all the pins on the hazard switch, then plug it back into the loom. Should cause all the indicators to come on?

One sec and I'll scan in the diagram and key.
