AlanR Posted February 18, 2014 Share Posted February 18, 2014 1972 MK IV. Has anyone experienced one side flashers 'racing' (usually sign of a blown bulb) but all bulbs fine. Also all bulbs works fine (normal flashing rate) with hazards switch on? Hazards switch was an after market addition. All worked fine for the last 20 years! Anyone have any ideas??

nang Posted February 18, 2014 Share Posted February 18, 2014 You've got a dirty connection somewhere or a bad earth. Probably a bad bullet connector.Tony. Quote Link to comment Share on other sites More sharing options...
RedRooster Posted February 18, 2014 Share Posted February 18, 2014 Check the mounting of the flasher unit.RR Quote Link to comment Share on other sites More sharing options...

Its a two terminal device and the case/can has no function but to hold the guts in place.If that's what you were thinking?Cheers,Iain. Kind of, had one short to the body of the car before, wrapped it in elec tape and it worked fine. Quote Link to comment Share on other sites More sharing options...
rlubikey Posted February 19, 2014 Share Posted February 19, 2014 All the old style rectangular 2-pin Lucas flasher units I've seen give a *low* flash rate with a blown bulb (or low voltage such as faulty alternator). Have you checked that removing a bulb actually does increase the rate?I think a high flash rate means too high a load, suggesting a short on that side to another circuit perhaps?Richard Quote Link to comment Share on other sites More sharing options...
