fitting LED indicators turns into nightmare

First all 4 blinkers flashing,no dash warning lights (apart from rev limiter),
now wont turn over, only get a clicking from cut out diode.
fuel pump primes as normal.
I have not mixed up the wiring, left to right or live/earth, If I had the LED's would not work.
The only combined circuits are dash and earth....
WTF ...too pissed off to investigate further at the mo

Sounds like your battery might need charging.
Also, I'm betting you've fitted the LED indicators with load resistors and that you've stuck the resistors in series with the indicators rather than in parallel.
EDIT: Hang on, read it again ... so the indicators are working? If so, scrub that about the load resistors possibly being in series.
Have you done the diode mod for the dash too?

Battery was at 12.70 v
No dash diode fitted, was hoping that the correct LED flasher unit would suffice, will read up on that now.
Not even going to look at bike untill tomorrow

No, the diode mod is essential when you fit LED indies.

This morning with 3 of the indies dissconnected, a fiddle with the wiring and the neutral light re appeared, she started.
The flashing of all 4 indies only started when I fitted the fronts and LED flasher unit, with the std flasher unit the rears lit up left to right(independant)
the front indies are poorer quality than rear/
Correct title oof dash mod ?
cant find

I never did it, and mine work fine...

Thanks flatlander, you found what I found, which tells me nothing because the files have expired.
So now Im thinking resistors are the way out of this...
What would I need and how are they wired in ?
In line with the positive ? wired to pos and neg ?
Sorry but my understanding of electrics is similar to a burglars sense of morals

I did a fair bit of reading up on this, apparently normal for all 4 indies to work without the dash diode mod.
Simplest solution, have the trick little LED rear blinkers and fit 23 conventional mini's to front, should balance all the evil electrickery

I had the same problem and didn't like the standard dash indicator light so I took that bulb out and installed 2 LED's into the dash surround at the bottom. Now I have a right and left LED indicator bulbs that instead of simply going on and off, they now go on (in low intensity) and then high intensity when the indicators go on. Think it looks cool and with it flashing like that I never fail to turn mine off after turning. And there is no problem with MoT's either.

I've done similar but I've used a bi-colour LED (essentially 2 LEDs in one package).
It flashes red when turning to port and green when turning to starboard - with the bright and dim effect you described - this is good as when the indies are flashing, you can never glance down between flashes.

That's only because you can't get your knee down to have a glancing look
