landrover598 Posted July 10, 2010 Share Posted July 10, 2010 My hazards decided not to work tonight when i went to use them, there was a short buzzing (rappid realy switching) from the relay box for a second or two and no flashing lights. The indicators work fine. The hazard switch was a new genuine lucas switch a few years ago, and i've just pulled it apart and the contacts are like new. Is there a seperate relay for the hazards, and any other areas of the circuit i should look at to fix the problems? 1984 110 elctrics btw Quote Link to comment Share on other sites More sharing options...

errol209 Posted July 11, 2010 Share Posted July 11, 2010 No seperate relay, just the switch. It uses the main flasher unit, which from what you say works fine. I'd suspect the permanent feed to the hazard switch (green or purple), the age of the flasher unit (struggling to flash all the indicators, OK with two or three) or the hazard switch itself. I have a spare switch, £5 and postage, PM me if interesed. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted July 11, 2010 Share Posted July 11, 2010 I had a similar problem Dave and a replacement switch resolved the problem. Mo Quote Link to comment Share on other sites More sharing options...
landrover598 Posted July 16, 2010 Author Share Posted July 16, 2010 I've just fitted a new lucas switch and it's not fixed the problem, infact, it's made it worse, when i turn the switch on, i don't even get the relay switching noise now, just nothing at all. Indicators still work fine Any suggestions Quote Link to comment Share on other sites More sharing options...

Indicators still work fine Any suggestions The only difference between the circuits (indicators / hazards) is where the power comes from. The indicators are fed by a green wire (ignition switched) but the hazards come off a purple (always on but fused) feed. Do all the other things fed from the same fuse (cigar lighter and something else) also work, or not? Quote Link to comment Share on other sites More sharing options...
landrover598 Posted July 16, 2010 Author Share Posted July 16, 2010 but the hazards come off a purple (always on but fused) feed. aahh, now the penny has dropped , i thought the hazards ran off the same fuse as the indicators, i'll check that fuse once it stops peeing down with rain Do all the other things fed from the same fuse (cigar lighter and something else) also work, or not? My cigi lighter runs off the aux fuse block, so i can't tell from that if the hazards came off the same supply as the indicators which is a ignition controlled circuit, they wouldn't work when the ign was off.

errol209 Posted July 16, 2010 Share Posted July 16, 2010 (and something else) It also powers the spare feed point located behind the cover at the back driver's side (RHS as you face front) of the rear tub. Quote Link to comment Share on other sites More sharing options...
