Is that a DS? Haven't seen any with a white face before. What color is the back light?

Glad to hear it works. Which wire did you use? Green or black and white?

Well after 2 hours of fiddling, and the good words of wisdom from the Troll we have success ! My Drifter has a tach, !!  Really the only tricky part was how do you tap-off the coil. Just not a lot of wire to work with, so I made an extension between the coil, and the lead, with a tap off it. All works well. Again thank you Troll

B+ simply means battery positive. This is a constant and will not change, so this is not what you want. There are two wires on each coil, beside the high tension lead. One coil has red and green and the other has red and black/white. Since the igniter is as easy to access as the coils, I would try connecting temporarily to that to see which one , if any, work. I can't say, for sure if this is going to work, since my W-650 has a similar system but there is a tach output on the igniter just for this purpose. If I get a chance, I'll stop by the dealer and ask how they would connect a test instrument. I'm surprised the tach didn't come with instructions.

O.K. I will have to take another look at the coil, I only saw one lead, and the spark-plug lead, but I'm not an electrician (nor do I play one on T.V. !) what exactly dose B+, and pulsed mean, and which one do I want to hook-up to, are they marked ? ......as always gentlemen THANK YOU !!

I don't have a wiring diagram for the ign. on an 800, but you need to connect the tach to the ground side of the coil. One side will be B+ with the ignition on, and the other will be pulsed.

So were do you make the connection ?
and thank you for the help !!

the tach signal is low voltage...actually a pulsed ground, so no, not the high tension side.

One last question gentleman ! (maybe ?)
The trigger lead from the tach is connected to the coil, I assume the they mean on the input side and not the spark plug side ?!?
