Indicators will not flash
« on: May 09, 2020, 12:33:02 PM »
Hello everyone.
Well the 400 is finally finished.
Starts on the button-sounds awesome.
Only problem now is indicators don’t flash-they come on-front and rear and console.
Relay clicks once-but no flashing.
Every other lightetc works perfect.
Relay swapped for working item-still no wink wink.
Open to suggestions please?
Thanks
Paul

Are you using standard bulbs?

Supposed to be 12V, 21W blubs. Are you certain that the replacement flasher relay works ok.
Where's that 10mm socket got to?

Thanks for advice.
New indicators are 10w bulbeds (not LED).
Pulled all my lovely wiring apart and connected 21w indicators to right hand side-
No difference-still no flashing.
I don’t think I need to connect all 4.
Confident new relay works fine as fellow forum member sent it to me after checking it works.
So where next??

Think I had this when I built CR Rep - seem to remember (was a few years ago) it was the wires the wrong way round on relay? (aftermarket relay was used)

Remove the relay.
Is it a standard unit?

See if you can try it on another vehicle.


Should work on cars etc.

I usualy go for a step by step appraoch with wiring...

Disconnect the indicators.,.... then connect just hte earth side. Apply 12V to theother indicator wire...see if it lights. Then reconnect...and go to the next step in the wiring to see where it tkaes power from ...like the relay. Disconnect...and apply voltage...see if the bulb lights. And so on. Once you know the basic wires connect corectly, and hte switch operates...then worry about the relay.

BUT....if none of them are working, and the earths are good, Most likely it's the relay or the switch.

Just to confirm-indicators and console light all work-just no flashing.
Relay is genuine item and working before being posted to me a few days ago.
However will try all suggestions offered.
Many thanks
Paul

It's unlikely to be an earth fault if the bulbs light up.  The relay relies on 44.2W of bulbs, (which takes 3.8amps) to discharge the internal capacitor so you get the correct flash rate.  That's 2 x 21W plus the little one.  If you go sticking 10W bulbs in or LEDs, it isn't going to flash.

Maybe it was damaged in the post?

They are mechanical after all.

Frequently need engine running for flashers to work
