PJM Posted August 20, 2006 Share Posted August 20, 2006 Need a real quick answer here guys if you can help. My daughter is on the A34 at Newbury without headlights in a 78 TR7 FHC. Unfortunately she has the manual with her so explaining abiout wire colour codes and relays is not a lot of help. Which of the relays controls the pop up headlights, which relay controls the main/dip beam and which fuses are involved. Any assistance greatly appreciated.

Raider Posted August 20, 2006 Share Posted August 20, 2006 When you say she has no headlights - are they popped up but won't work?If so the headlamp switch is probably burnt out as there is alot of current going through it and it isn't relayed!Solution is a spare switch (unlikely I know) or some re-wiring. I think the only solution will be a recovery truck.If the pods are down but the lights work in theory she can disconnect the wiring to the motors and wind them up manually. Again - probably calling breakdown assistance is the most sensible thing to do right now Link to comment Share on other sites More sharing options...
TRishaTR Posted August 20, 2006 Share Posted August 20, 2006 As you look at the fuses/relays (having removed, maps, gloves, rain-X, manual & some old murray mints from the glove box)......The relay at the bottom left is the run/stop for the left hand lamp (there's two similar relays above this one). The relay for the Right Hand lamp is at the bottom right as you look.Not sure on the fuse.... is there one? :-/ Honestly can't recall. If ur stuck I'll nip out and get the hand book. Can they raise the lamps manually or are they 100% duff, and raising the lamps will just give two dead eyes? Link to comment Share on other sites More sharing options...
PJM Posted August 20, 2006 Author Share Posted August 20, 2006 Headlamps are down but will wind up manually and give main beam. Apparently left hand relays are in place but right hand ones are loose Link to comment Share on other sites More sharing options...
Raider Posted August 20, 2006 Share Posted August 20, 2006 Main beam only?I would go for winding them up - use the headlights to get home and sort it out in daylight.Off to check a handbook for the fuses though ;) Link to comment Share on other sites More sharing options...
Raider Posted August 20, 2006 Share Posted August 20, 2006 If it's the one with a bigger fuse box (12 fuses) according to my handbook there are 2 fuses that look after dip beam - bottom left hand and bottom right hand both 25 amps. Link to comment Share on other sites More sharing options...

PJM Posted August 20, 2006 Author Share Posted August 20, 2006 She has just arrived home safe and sound, thanks guys. Looks like the circuit tester will be doing overtime tomorrow (if I can explain how it works by phone). Link to comment Share on other sites More sharing options...
PJM Posted August 26, 2006 Author Share Posted August 26, 2006 A new switch has been fitted and all works well. Link to comment Share on other sites More sharing options...
