LED flasher unit
Hello.
On my car I have LED indicators on the sides and rear.
When I built the car I fitted LED resistors in line, but of late these seem to be working intermittently.
I’ve tried to re-earthing them to no avail.
So I thought I would buy one of these Led Flasher units( the one I’ve brought says it can be used with any combination of LED’s and Standard bulbs)
I’ve connected this up the same as the standard flasher unit but I can’t get it to work. The indicators just light up but don’t flash.
I removed the earth from the LED resisters thinking that this may be the cause, but this also didn’t help.
Has anyone else encountered this problem and what was the cure Please?

i'd take the resistors out entirely

Have you not removed the resistors completely?? Make sure the wiring to the LED flasher is correct - i did the conversion and two connections needed
swapping over in the holder. You still have a standard flasher unit i presume to feed the flasher relay??

Paul. Does the wiring system have a relay and a flasher unit for the indicators?
Or does one unit do both jobs? After reading your answer I'm thinking I should have replaced a relay with the new unit not the flasher.

Sorry my mistake - t'other way around. Retain the standard indicator relay and swap the flasher units over.
You have a permanent live feed going into the LED flasher and this then provides a flashing output to the hazard switch and indicator relay. Make sure
the earth and Flasher unit output are the correct way around - its these that i needed to swap over from memory with the flasher unit i bought

Ok thanks. Looks like I better remove the resisters completely and then see what I've got.
Thanks all.

i got told by the local bike shop that these basicly need wiring so that the new relay is before the direction switch, and they start working when
they earth out at the light, so it would be wired as:-
ignition feed - new relay - left/right switch - lights x3 i would guess - earth
so u would need a 2nd relay to to do the 4ways, 4ways would be
battery feed - 2nd relay - 4way switch - all flashers lights - earth.

The flasher relay is generally set up (on a car) to provide 2 permanently live outputs, one going to the Hazard switch and the other going to the
indicator relay.
This allows the Hazards to work with the ignition off while the indicators then need a switched live to operate so only work with the ignition on.

I removed the resisters and tried the live and earth wires the other way around and it still didn’t work.

guessing and removing LED resistors isn't gonna work.
you need to supply us the pin numbers on the relays.
the old electormechanical units have 2 pins and work by having a load i.e. the bulbs opreate a bimetaillic strip.
LED flasher use an electronic timer so need to have power - hence will have at least 3 pins.
have a looksee here; shows pin numbers and how to connect them.

No the old one also has three and the numbers are the same on both 31 49 and 49a

Just for everyone’s information I contacted the supplier and ended up sending the Flasher relay back, he sent a replacement which worked perfectly
even with the resisters connected.
