These guys and their freaki'n wire questions, EH?

Hi all. Still searching for the problem with my post-paint electrical issue. I have tail, marker, park and RIGHT turn signal but no brake lights or RIGHT turn signal.

I've attached some pics of what I have on the right side of the trunk, hoping that you can help me sort it out. I read post after post before approaching you all, and I have ZERO ability to read a wiring diagram, so please forgive me for what I'm sure is a repetitive and tedious whine.confused smiley

THANKS as usual for your valuable and MUCH appreciated assistance!!thumbs up

Frank

Disconnect the two rear lamps joined together. The side marker and the running light are the two that get coupled. The turn signals are each on a separate circuit and the brakes are on the same circuit. See Arlen's post in the other thread.

MY APOLOGY!
I neglected to check my other post before posting this one, which probably creates a "Stop making duplicate posts, DUMBASS" situation for which I am again sorry.
I will take this information, and the freshly printed wire diagram a retreat to the garage and work toward a resolution.
Consider me self-reprimanded.

Thanks

Frank

I'm GETTING THERE!

Hi Trevor, and THANKS! You and Arlen have been a BIG help!

I have all lights working at this point, with the exception of the BRAKE lights.
The diagram indicates a BLUE and a LIGHT GREEN with PURPLE make the circuit. My problem is that NEITHER of the 2 GREEN/PURPLE wires are LIGHT GREEN! I have had two independent verifications and we all agree.......green is green and there is NO difference in dark/lightness of either wire.
I used 1 to get the turn signal working, leaving 1. I connected this to the BLUE that is available, and get no response.

The 2 I'm referring to are in this pic, to the RIGHT of center and BOTH, as well as the BLUE wire come out of the loom that runs across the back wall of the trunk.
ANY IDEAS?
THANKS AGAIN SOOOOO MUCH!!
Frank

According to the lucas colour guide green/purple is the brake light, light green/purple is associated with the flasher indication (think all the light greens are up the front). The WD says green/purple to the brake lights (not light green).

By the way, just posted a marked up copy of the WD on your other post.

The actual wire from the light socket may not be colored striped. Is that your question?

Correction - should be green purple from each back light to the green/purple (brake). Solid green to the green/white (pass side), solid green to green/red pilot side (indicators).

Thanks for all your help guys!
I fought with door mirror mounting this afternoon, so I'll get back to lights tomorrow. Still don't think I have the correct wires available at the passenger side trunk, but it's the only place that I disconnected wires at (presumably BRAKE) so I'll certainly use your information and report results tomorrow.

This is ALL very much appreciated!!thumbs up

Turned the headlights on today. Tried to change beams and lights went OUT! I am becoming increasingly more frustrated.

Quote: I am becoming increasingly more frustrated.

That's why I have a stocked fridge in the garage.....

The low & hi beams are switched at the stalk. You get either one or the other, not both at the same time (otherwise wire likely to start melting.....). As the low beams work you know you have basic power for the headlights, the dash switch is working and a good ground at each light (all common to both).

That leaves the stalk low/hi beam switching function (unlikely as it works in low beam), blue/white wire, blue/white wire connections & headlight bulb high beam filaments.
Take a look at the connections up front, make sure the blue/whites go to blue/whites (find the wires at the headlight & work back) & the connectors are clean. Pretty sure you will find something unplugged or a poor connection. Its a good idea to do that with all 3 headlight wires/connections just to keep future problems at bay.

You really do need a voltmeter or test light, it will save a lot of time & frustration. The way I would go about this is to first find the blue/white wire from the stalk switch at the front (behind the grill I believe, it will be the one in the loom, not coming from the light) & make sure there is 12V there when the hi beams are switched on (and again with the flasher). That will confirm everything upstream is working correctly (stalk switch & wire integrity to where voltmeter connected) then start cleaning/checking all connections. If you don't confirm exactly what is working as you go you will end up chasing your tail.

Alternatively you can connect the blue/white (hi beam wire) from the loom to the blue/red (low beam wire) from the headlight unit & with headlights switched on the headlights should be off & only come on when the high beams are selected (confirms everything to the end of the blue/white in the loom is good). Similarly you can confirm the hi beam bulb filaments are good by connecting the blue/red (low beam wire) from the loom to the blue/white wire (hi beam wire) from the headlight unit - the hi beams should come on when the headlights are on & the low beam selected. Remember to turn the lights off when switching the wires around.

Someone out there (John Twist maybe?) posted a master list of all the British wiring color combinations and their intended use. Worked a treat for me, but then my wiring harness hadn't been bodged like so many do. I have this chart posted in my garage and refer to it often. That, and the Prospero Garage Midget wiring diagram have made Lucas not such a bad word in my shop. I'll agree a stocked fridge in the garage doesn't hurt either.

Beating back the gremlins!!

Well, I've spent some number of hours in the garage with paint thinner, toothbrush, files and tape working toward getting to drive my car before the snow flies.
I've met with measured success and have restored function to ALL lights with the exception of the original problems: brake lights and headlights.
The headlights might not be a big deal. I am NOT turning them on until I get my relays and have them installed.

I tested the brake switch (with multistrand wire.......no paper clip available). Don't know if this would have affected the test, but when I jumpered the switch, key on, I got NO response from the brake lights. Is there a second method of testing this switch?

Also, some of my problems may be coming from this odd switch that screws into the bottom of what I assume to be the control box. Wire colors indicate that it has something to do with the turn signals. Anyway, one of the two very odd looking connections is loose and looks as though a strong breath could knock it off. Can you identify this switch from the pic, so that I can begin to hunt for a replacement?

As usual, THANKS A BUNDLE!!
Frank

Cheers on working through it carefully! The do-hickie in the pictures is the brake light switch. You are correct that the wires going to it make it LOOK like it has something to do with turn signals, because you are seeing green and red, but if you scrape that red paint off, you should see that it is actually Green and Purple... which is the color for brake lights.
