Don't think so
Mk 2 also introduced the low fuel warning capability in conjunction with the appropriate fuel tap I believe
I agree, and I believe the way to tell is a V1 shows the dial up to 120kph/rpmx100, and the V2 is 140kph; however the v1 did have the low fuel warning.
Is anyone running one of these with Varitronic, using the DC feed? (or has this been covered in this mahoosive thread somewhere?

)
Have the buttons been improved at all?
Negative on the low fuel warning and speedometer needle for V1. I run one (very solid BTW).
The 120 is RPM X10

Yep you're right, well partly... No fuel warning on V1...I'm disappearing up my own proverbial with these, was there a V1.1 or anything?
However...120x10=1200, 120x100=12000, so rpm is x100, as can be seen on the face

Buttons are the same on both versions.

I'm running a Wassell full DC system on the bike in question, a SIL GP.
Connections
I followed the instructions (maybe

) but essentially there is a "powerbox" which connects between the device and the power supply. 3 wires need to be joined into the headset: Red = Battery +12V; Brown = +12V supply to the lights; Black = Earth.
Need a bit of help here. I'm running DC
My power box has the black, brown, red, but theres another black (arrow) coming out on it's own the other side of the box. Any clues to where that one goes would be gratefully appreciated.

Both should be ground/earth

Thanks. Tried it and getting nothing.
Red to battery, both blacks to earth and brown to light source.
Electrics are the devils work.

That black wire should be in a plug! (At least it is in mine!)
Mine is a V1 and has the 3 wires on the input side and 4 wires going to a 4 way plug (well socket to be technically correct) which connects to the speedo. The little connector on the end of your spare black wire slides into the back of the socket.
If you have a full Wassell dc system your brown input wire has to be connected to one of the yellow wires on the Wassell rectifier. The SIP speedo relies on the AC ripple to calculate the revs which is missing from the "lights" circuit on the Wassell dc system.
It seems a bit scary connecting direct to the output of the stator, but apparently it works. (No responsibility taken if it blows up

)

Yes agreed there should be a plug connector on that which connects to the unique cable that goes to the speedo unit.
Mine (v1) works with the brown spliced into one of the yellow wires before it gets to the Wassel rectifier.

Thanks.
Everything else is connected but there doesn't seem to be a connector for it
