Im just about finishing up my wiring and am having a few issues with my indicators. Im using a 3 pin electronic flasher relay with led lights all round. I think that the relay is knackered. when the relay is working correctly i am assuming that the output from pin 49a should be a pulsed 12v? I am just getting 12v but then when all lights are connected just they don't light up at all.

The other pin on relay goes to the warning lamp so i tried the indicators using that output and this time every thing came on when selected (L, R and haz) but
just came on solid ie no flash? Am i right in thinking this proves my wiring is ok but flasher is duff ?

Cheers

i would say you need a pair of diodes on the circuit. what hazard switch are you using?

Its a savage switch (hazard) with a rocker switch for indicators. Its wired with diodes, with a 12v feed every thing works as it should. I'm just not getting any pulsating voltage to make it flash. Think its got to be a duff relay.

Have you tried substituting one or two LEDs for a conventional bulb as a trial? Sometimes LED setups can behave very strangely. Are you sure your diodes are wired correctly (polarity wise)?

Diodes are defo right way round first thing I checked. I will have a play with the conventional bulb in the morning.

I should still be seeing a pulsing voltage from the relay if working correctly though shouldn't I? It was loaded up with all the indicators, bar the side repeaters.

do you have a diagram of how you wired it?
your diodes should be on the left and right indicator wires where they connect to the hazard switch

Wired like this:


Hazard Wiring Diagram

dont think thats right mate! will take a look

first set of contacts
pin 1 feed to flasher
pin 2 permanent feed
pin 3 ignition feed

second set of contacts
pin 1 return from flasher.
pin2 left and right ndicator feed with diode on each letting voltage away from switch and not back
pin 3 not used
the only wire i cant remember was where i fed the indicator switch common from!

Ive bench tested the relay today and its definitly Fubarrred. When the new one arrives wiil take it from there. I think my wiring method works in the fact that every thing comes on when selected but just not flashing.

I will make a note of your connections tho incase it still doesnt work

It was a dodgy relay new one fitted and all works perfectly

For info the above diagram works using savage hazard switch and a toggle ind switch.

better that way than pulling the loom apart
