Hillcourt Posted September 20, 2012 Share Posted September 20, 2012 First of all thanks for a great forum, its been great to read.Now for my question.I have a 1979 spit and was having trouble with rear lights going off when braking. Cleaned up earths but think we had a short. Funny things were happening where we could get brake lights and no rear lights then vice versa. Also indicators stayed on or flashed slow.After a while we got nothing and even noticed Windscreen washer jets not working. Fuses are fine. Could be flasher units/Stalk?Thanks in advance Link to comment Share on other sites More sharing options...
Velocita Rosso Posted September 21, 2012 Share Posted September 21, 2012 HiCombination of quite a few things hereSo you have a 1500....does it still have the night dimmer relay in the nearside rear wing hiding in there?If so remove it and connect all the wires.The cause of many complaintsThen check all the earth wires at the rearFlashers could be poor earth`s or the wrong size flasher can ( I made that mistake once)However there still appears to be a fuse holder problemYou need to remove fuses and check that the wires are not loose at the backRemove fuse box ,fit fuses, turn your lights wipers etc on and then jiggle the Lucar connectors around whilst the box is inside the battery cavityThen lets hear....

rotoflex Posted September 21, 2012 Share Posted September 21, 2012 My car a few months ago began to exhibit behavior like that (and some others), & no amount of cleaning of contacts sorted it out. Replacing the combo brake/tail light holders with new items fixed it. Apparently I had reached the limit of fixing the ground-to-contact connection inside the old holders or something.The new ones have an additional, separate electrical connector for ground, unlike the originals which grounded through the springy things that hold the bulb holder into the tail light housing. That also might be part of why they work now: the springy things may have been making poor ground contact through the tail light housing. The additional ground lug means that you'll have to run a new wire from that lug over to a nearby ground lug - a bunch are gathered nearby on a light housing.Be aware that the quality control on some of the new tail light bulb holders is spotty. If you get one, first insert it into the tail light housing without a bulb, & then extract it. If it comes apart, exchange it for another until you get a good one. If you insert it with a bulb in place, & than it comes apart when you pull it back out (like when changing the bulb), it becomes a problem trying to get the thing out without breaking the bulb.

Velocita Rosso Posted September 24, 2012 Share Posted September 24, 2012 Two man jobTo cross check,attach bulbs to end of wiring .....out of the bulb holder..........thus proving or eliminating the bulb holderDim one side brake lights.....did you take out the dimmer/nightswitch from wing............could still be that or earthHowever all could be earthCreate a `master` earth ,attach all black earth wires and then to a `master` back to earth on battery,then see what happensHave you checked the connectors at fuse box, if live in OK, run a slave wire off each of three terminals with a bulb holder to check if live is coming out Link to comment Share on other sites More sharing options...
Hillcourt Posted October 10, 2012 Author Share Posted October 10, 2012 Just a quick update for this thread.Got the car out and decided to have a day on the lights. Turns out main problem was the wire from the back of the master switch in center of the dash was shot somehow. stripped both ends and no good. ran a new wire and works!. also replaced the whole connector block in wing.Fair few hours but now i have rear lights. Apart from reverse i think. sensor on gearbox? Link to comment Share on other sites More sharing options...

Check first at the lights themselves with a meter between ground & the wire to the reverse lights. With the ignition on & the gearbox in reverse, it should have 12v.If you don't have 12v there, the gearbox switch would be the next place to look.If you do have 12v there, the problem is related to the lamps, lampholders, or their grounds.
