LED indicators!

[leopard_pagan]

grrr... dont work!

i have:
a "honda" LED indicator relay fitted
2 "load resistors" fitted to the front each side.
normal all round resistors built in at the back.

problem:
no load resistors= front indicators working fine each side & bright, BUT rear are "hazard" lights & dash is not flashing.
with load resistors= dash flashing, rear normal, but one side kinda dips in the flash, front hardly light up!
no hyper flashing at all with any combo.

i have left them on no front as TBH i prefer people behind me knowing what i am doing!

Firstly, get rid of all the resistors. They're not needed.

If you use an electronic flasher unit (a switch based on time rather than the standard one based on resistance) then you won't need to add resistance to the wiring.

I assume when you say rear are 'hazard lights' that both rear indicators are flashing at the same time? If so, this will be because current is passing through the indicator dash bulb, joining both the left and right indicator circuits together. I had this issue when fitting led's to my nc30 but after a bit of head scratching found a fix for it.

Remove the indicator bulb (after removing all resistors!) then see if the indicators flash properly.

If they do flash properly when the bulb is removed, then follow the info in the thread below and install diodes in the dash bulb wiring circuit so you have a proper functioning dash bulb once again. The diodes simply allow current to flow only one way through the circuit, this is how newer bikes with led indicators get around the issue.

If they don't flash properly after removing all the resistors and the indicator bulb then your electronic flasher unit is not suitable, try another type. The cheap generic units generally work well.

Let us know if you have any dramas after trying this.

Not sure what you mean by this - but remove them!

> built in means they are already soldered in place and i cant get to them! already tried to open the lights up to re-solder the circuitry as Chinese circuits are CRAP (i work in electronics & see the shite every day)! but at £35 for the lights... cheaper to replace than repair!
i have a LED flasher (oxford) relay already fitted and does fcuk all to the situation! ...or maybe is the only think stopping the hyper flashing.....

when i remove the load resistors i get hazards at the back, no dash flashing.
i was told by auto lekys that the dash must light up for MOT.

i do agree that the dash light is the culprit, i may even have those diodes in my stores.. if not next day i will :0)

Diodes in hand.. soldering iron, heat shrink n lead solder...

where did you fit yours?
behind the clocks?
i want to fit them just in front of the indicators them selves... easier access than clocks wiring...

If you use lamps with built in resistors, you can use a normal OE relay. If you use an LED relay, you must have all four lamps the same.

I think your problem lies in the fact that you have too many different setups going on at once and they aren't compatible.

[leopard_pagan]

LEDs all round, compatibility maybe an issue, but not one i can fix.
as far as i can tell, ALL the LEDs have resistors to work on a 12v system.. with out them the lights will simply not work.. or blow up (fun when that happens).... as did my old LED rear lights as i fitted one resistor to EVERY LED.. things only became an issue last year when i changed the front indicators to LED... looks like the same issue is still there.

i think i will do this diode mod behind the clocks.. will take clocks off and have a look see at the wiring behind/how much i have to play with.

Exactly.

Diodes fitted... these came from my local auto electricians so not 100% sure what the IN part number is..

LEDs now work bright and intendant, no hazard lights.

BUT... i no longer have the dash indicator working! could this be an incorrect diodes? the bulb looked fine when i had it out.

+ not happy with the Chinese crap soldering! half of one side of the rear lights now arent working! i KNEW i should have had them apart and re-soldered every joint on the circuitry when i had the chance! but i bloody soon will do it!

Is the dash bulb an OE filament type or LED?

If it's a filament bulb it won't work if you have LEDs all round and an LED relay. There won't be enough current to light a filament bulb.

[leopard_pagan]

ditto.... + the two wires going to it are both earth & live depending which indicator is being used.

when i have time i'll play more with the dash bulb, maybe a dual LED yellow/yellow may do the job.
