[Zmagnette] Wiring problem

Amongst the many, many things I know virtually nothing about, chasing electrical circuits, particularly anything mildly bordering on electronics, is high on my list. House wiring . . . hark, I've wired entire condominium projects, and they didn't burn down. Relays and all that . . . I'm lost. BUT, I have learned this much, FWIW, and Mike Ash (naturally) already said it. I've found the hard way that new paint and ground are an oxymoron. It just kills ya to scratch up/away new paint to make stuff ground, but by golly, that's what it takes sometimes. The best trick that was passed onto me, was whenever possible, use a brand new (NOT original, 60 yr. old flattened ones) "Star" washers. The guy passing this onto me preferred external ones, but . . . The little ends will bite through the paint, and you'll have a good ground, without scratching around with a screwdriver, etc.

Thanks for everyone's good ideas and starting points. The DB10 relay box has the cover on correctly and those wires are correctly attached. The flashing stops when I disconnect the green wire to the double connection where it meets the green to the stator tube and sends a green back to the flasher. I will follow some more trials tomorrow to see if I can distinguish if problem can be isolated to the flasher or stator wiring.
The sneak current to the dome light made me wonder about my grounds too, I will re-check that wiring under the dash too. I was frustrated enough to work only on bumpers and over riders most of today.

Hi Rodger, I have the wiring harness business in Australia and a couple of Magnettes so I may be able to assist your trouble shooting.
I assume your car is fitted with the Lucas DB10 relay box and your rear signal lights operate as stop lights and turn signals.
The first thing I would do is disconnect the wires to the stator tube. The wires may have become twisted and shorted. If the condition persists then you know it is not caused by the stator tube wire or the flasher switch. If the condition goes away, remove and chek the stator tube wiring and switch connections.
I would also check the connections to the roof harness behind the dash. Make sure the wires are connected colour for colour - white purple and white brown for the two rear signal lamps and brown green for the interior light. Again, you can disconnect these and see if the problem persists by checking the front flashers.
And the other thing to check is the DB10 relay box.
On terminal one you should have a green with brown wire which comes from "L" on the flasher can.
Terminal 2 should be a green with white wire for your front right flasher
Terminal 3 should be a white with brown wire for the right rear signal lamp (brake and flasher combined)
Terminal 4 should be a green with yellow wire from your stator tube to turn on the right turn flashers
Terminal 5 should be a green with purple wire and is the input from the stop lights switch
Terminal 6 should be a green with red wire and is for the front left flasher
Terminal 7 should be a white with purple wire and is for the leaft rear signal lamp
Terminal 8 should be a green with blue wire and is from your stator tube to turn on the left turn flashers.
These are the standard Lucas colour codes. If all this is wired correctly, and your problem still persists, I would disconnect the wires on terminals four and 8 and see if the condition goes away. If it doeasn. I would suggest the DB10 box is faulty.
Let me know how you get on.

I have been frustrated with a glitch with my re-wiring job. This is a 59 ZB with a new British Wiring harness. Regulator is the original, as are horn and signal light relays. New flasher unit form Moss. Re-wired stator tube. Most electrical functions seem correct, e.g. the heater fan motor, the ignition, headlights. However, when I turn on the key all four signal lights flash, along with the dome light. I have checked connections to dash panel and relays and can't find a problem. I have had trouble confirming green wire continuity from fuse box to all connections. Finally, I have four green wires at the fuse box, not the three illustrated on the ZA diagram I have in my WSM.
I need advice on how to troubleshoot this problem, everything I check seems ok or doesn't make any sense. Rodger

No, I haven't fallen off the face of the earth. Family and Employer
have conspired to keep me from spending as much time on the wiring
diagram as I had hoped. Also, building a set of icons to use for the
various components has taken more time than I thought. The news is that
I've completed building a single wiring diagram that has all of the
options for the ZA, ZB, ZB Varitone both RHD and LHD. It is being
checked for accuracy and completeness so it should be ready to send out
soon.
