think you may have answered your own question .........to the brown wires in the headset which ive read everywhere should be main live got nothing. have you got power to the brown wire ??

Im very new to lammies, but scoot starts, lights/horn work, start the scoot pull out the brown wire and lights go off, so am assuming brown is live!
but.... put a multimeter on brown wires in headset, with scoot running and no readings! again scoot switched on and multimeter on green wires (ignition?) got a reading!

Hi Jock,
You mentioned pulling out the brown wire and the lights go out. Therefore, there is power on the brown wire.
You said you connected the red and brown wires from the speedo to the brown feed above. What you don't say is that the speedo black was connected to a GOOD earth.
If that connection is made it looks like you may have a faulty speedo.
Why not connect it up to a 12V battery to check this? (They will work with a 9V battery if you're stuck)
This is actually a neat way to set them up instead of having to enter all the setting with the engine running.
Good luck!
Nigel

cheers mate, all sorted now. We did test on a car battery and it worked. It turns out it was his regulator that was the problem, he had a 5-pin regulator and no battery
it seems it wasnt chucking out enough voltage, soon as we changed it for his old regulator (3-pin).....bingo it worked
cheers

Hi, excellent an informative thread this ....
Just fitted my SIP speedo and I've a couple of questions please.

Rev counter seems high, I used sideouts initial settings and set the pulse to 1, but it seems high. I'm sure I read that it should be an alternative setting but I can't find where I read it. What should the setting be for a standard lambretta with electronic kit etc. A/c with speedo powered by d/c battery.

Also, is it possible to set the rev counter to use the digital display with speedo using the analogue needle? I can't seem to find that option.

Cheers Steve

This is in this months Scootering Mag and thought it would be helpful to some....








.......I can see removing the plug in the rain and at night from a standard cylinder a bit of a mare.....

[Grumpy225]

I can't see how this would be more accurate.

[jonashford]

Because it's in direct contact with the plug!!!
