Indicator problem HELP

[royhall]

I'm looking forward to knowing what this problem is. But probably not as much as you are Graham.

Trig... clutching @ straws here... but an overly fast flash rate can be the result of too high a current draw... ie check the bulb holders / pilot lamp areas for corrosion.

Unfortunately this theory doesn't fully the high-revs relationship... but you appear to have tested / swapped everything.

I always run an extra cable to inside the indicator for a more reliable earth.  There's plenty of extra earth females inside the headlamp shell for the front ones. This eliminates most indicator gremlins.

Trig are the indicators the single wire type or the twin wire type? Have you tried it with different indicators just to see if the fault lies with the indicators. Not sure why but I'm thinking earth fault here. Thinking that the vibration is making the earth lose and gain contact so fast the bulb is flashing as fast as a result. This would mainly be if the indicators were the single wire type and relied on the earth at the junction between the frame and indicator, even 2 wired types could be affected the same way if the connection in the indicator was loose.

The indicators are twin wire and the stems are rubber. Will try another set and see what happens. Will keep trying and keep you posted.

I'm sure I'v said it before but I will say it again 
My 250u indicators corroded inside causing them to stay on.

Did try that Mick when you said months ago. All nice and clean, no corrosion found

UP DATE, Hairy does it again! Fitted a £2.25 LED relay and everything is fine. (except the relay has a beeper built in) well, the world is not perfect.

Cheers for all the replies

750F1's had indicator bleepers, and they WERE perfect!

Kinda pity you've solved it in this way.... was looking forward to learning the cause of the problem. Anyways, at least fettled.....

You may have masked the underlying problem but if it works for you then that's great. An electronic unit will probably have its  own voltage regulator inside, which will be insensitive to any battery voltage/charging excessive fluctuations and the flash 'timing' will be governed by electronics rather than the standard electromechanical style flasher, which uses a capacitor discharge circuit into a relay.There is also the 'Signal-stat' version mainly fitted to USA bikes that uses a bi-metallic strip like the old Lucas car ones,which my have been less sensitive.

Love reading your replies on electrics Ash & Lobo. Have learned a ton of stuff without even touching the bike. Excellent. Cheers Roy.

Exactly what I was thinking

Fault finding always difficult at a distance. I have a main customer in Lithuania who uses my PC controlled test rigs and it's a nightmare fault finding. What you could probably sort out in 5 minutes if you were on site can sometimes take a week to get to the bottom of.

Thanks Roy,

Sad fact of the matter is I'm right up there with the monkey typing Shakespear...tho' he probs gets it right more than me.

I'm 'new' back to bikes & just cannot match the sheer bloody 'Honda' experience of the old hands who get a whiff of a prob & intuitively know the answer.

Ho hum.

Simon.

That may be so Lobo but the couple of electric gremlins I have had you got spot on straight away. Saved me a pile of time and headaches. Your probably better at it than you think. Cheers.
