SIP Lambretta Digital Speedo
Hey guys.. It's no doubt been mentioned in one of the 20+ pages of this thread.. but I was having the same problem with my Lambretta SIP speedo as several others.. it would just seize up.. or not work at all.. I tried 2 speedos, 2 black boxes, 2 different regulators and the simplest wiring possible.. but no luck.
It turns out it IS the plug.. it has to be a proper resistor plug.. ie: NGK, BR9ES.. I thought that just by leaving the resistor cap on a regular B9ES it made it a resistor plug! My bad! I swapped out the B9ES with a BR9ES and boom! everything works as it should.. perfectly.. no need for the BGM regulator or any special pieces..
My bike is non battery.. so it's just Brown/Red (from the speedo) wired together to my AC power from the stator and Black (from the same speedo connector) to a solid ground.. Done!
Sorry if this has been hashed over.. but after trying everything under the sun.. it simply boils down to using a resistor plug.. not just a plug with the resistor cap left on.. BR9ES, BR8ES etc..
Thanks for all the input here too..
... and just for extra info.. I'm using the BGM ignition with the simple MB harness.. no battery.. and this 120w regulator.. wired as I wrote above:

From speedo (brown/red tied together and connected to brown (from the harness / stator) and black from the same connector as the brown/red to a solid ground.. that's it.

Hi chaps, at the risk of extending this thread as nauseum. Is there any advantage then of using a battery to power the speedo? I only ask coz it would be easy for me to run a line from the battery that powers my spots. Or should I just take the power and rev feed from the circuit ? Thanks steve

The only advantage I found was that wiring to the battery meant that I could do the fairly lengthy setup procedure in my garage without fear of CO poisoning. Bear in mind that the battery feed must be switched, otherwise the speedo will be permanently illuminated.

I have 3 now, 2 on Wassel DC conversions with a battery, one without. As Norm says, using a battery allows setting up without the engine running.
However, the other advantages are:
If you don't have a battery in the circuit and you're stopped a junction and don't get much output from your 12V feed then they can go through their start-up sequence. No big deal as they remember the settings, but obviously, with a battery you don't get this.
I also like to have a battery because if you want to take some readings off it after a trip, distance, time, average speed etc., it's much better to do it without the engine running.
Oh, and keep the thread going
I must summarise all the points and submit them for a FAQ at some point Cheers,
Nigel

Nigel,
I have a wassel conversion and battery, I am about to fit a sip speedo. Where do you take rev pick up from when using battery? I wa planning on fitting the power box at back of scooter near to battery and stator. Any pointers greatly received, I gave resistor plug already. Andy

Hello All,
Mate of mine has a lammy gp (no battery) and bought a sip digital speedo, and we have spent all weekend trying to install it!!!!!!!!!!!!!!!!!!!!!!!
Has anyone got photos on how they wired into the headset, we have tried everything but cant get it to power on at all!
Its all connected up by the book, with a resistor plug, scoot starts with lights/horn no power to the speedo. tried a multimeter set on ac
to the brown wires in the headset which ive read everywhere should be main live got nothing. Multimeter on green wires show a reading which i think is ignition
Its all earthed ok, red/brown wires from powerbox joined and tapped into brown on headset - still nothing, dont know if im being stupid here but after
a whole weekend trying to get it to work am stumped
any help would be appreciated
cheers
