    Hi All,

    I've got a little problem with the Indicators on the RV.

    I wonder if anyone's got any ideas?

    The indicators, just recently, have been flashing really fast when turning both Left and Right.

    I have checked all the wiring/earth's etc.

    When I operate the Hazards, all 4 units flash at the correct speed and are bright.

    New Light units have, over the past year,been fitted Front and Rear and terminals clean ok.Been ok until the other day when it just started doing this.:Sad:

    Thought it may be the voltage regulator but they do this whether the engine is running or switched off.:Doh:

    Any ideas gratefully received.:thumb:

    Im assuming you have checked that you dont have any bulbs blown???

    If a bulb pops in our Jeep they flash really quickly

    Hiya Dazzer,

    All the bulbs flash at correct speed when on Hazard, and Left and right flash, albeit really fast when indicator stalk used..The lamps on the instrument cluster also light up.

    I'll check further. Cheers.:thumb:I'm hoping it isn't a problem with the indicator stalk/switch itself.

    I agree with dazzer, thats a classic sign that you have a bulb out.

    Would that apply to both sides though?

    I have no repeaters fitted and there's only the Front, rear light units and the instrument panel lights.All work ok.

    Forgot to mention I have a towbar / Socket fitted.Could it be something to do with that?

    It has the usual cover over it.It did rain quite hard the other day.

    No it shoudnt do.

    I was reading about it on yahoo earlier. Its to do with an increase in current.

    If you have one bulb down it speeds up the other blinker. Its happened to me.

    Is there a way to isolate your tow hitch and then try them

    No it shouldnt.

    I was reading about it on yahoo earlier.

    Its to do with the extra current load when one bulb goes down. Its happened to me.

    Can you isolate your tow hitch and try them again.

    Steve have you fitted any LeD replacment bulbs to the indicators if so they dont draw enough current, and can cause your problem
    as can a failing relay or bad earth
    you say you have a tow bar socket, plug in a light board and see if the extra bulb slows thing down

    Hi Geo,

    No LEDs fitted to the indicators or the Indicator instrument panel.They are still normal filament type.

    Good idea regarding the tow socket.:thumb:It'll test the wiring's still ok as well.

    I'll have a look tonight.:thumb:

    Cheers.

    Hi Geo,

    Well I tried the Bike rack on the back with the lights connected up and they still flash fast in normal (indicator) mode but ok on hazards....:Doh:

    I have found flasher units on ebay that might do the job if it proves to be the unit.

    What's getting me is they work normally in hazard mode.:Doh:

    Hi Steve found this after a search on Google don't know if it will help!


    I get this on mine from time to time. Turns out there's a water leak letting drops of water into the socket for the rear lights and causing a short. Once it dries out, it all works fine. When the rain stops after a wet period, I usually spray some electronic cleaner in there which evaporates the water real fast...

    Might be something else on yours though.


    Regards Pat

    Cheers Pat.I'll take a look inside the units.It did Pee down the other day.

    The units are new and were sealed to the body with silicon to hopefully stop this happening.

    Worth a look.:thumb:

    sounds to me like a failing flasher unit Steve.

    could be it has a seperate hazard unit so will work ok on hazards only.

    Makes sense John.I'll delve further into the circuit diagram.

    Hopefully I can get another reasonably quickly.:thumb:

    Does anyone know if there's a maximum flash rate specified in the MOT/Law for indicators?

    They currently work and flash but VERY fast.:Eeek:

    Regs req between 60 and 120 flash's per min
    or 6 and 12 per 6 second interval its easyer to time:thumb:
    Engine may be run if a slow flash rate is found, before applying fail criteria

    I had this before on my car and it turned out to be the flasher unit.

    Same symptoms exactly.

    Maybe hazards work OK as they need to flash all 4 bulbs so there is no spare current around to make them flash fast.. dunno but its my guess anyway.:Laughing:
