here are the circuit diagram,i builded by myself,it work like a dream.
note:the very important thing is the "normally open switch"i fitted a GOOD reed-switch near the gear lever,with a magneto...
with the trimmer you can adjust the "break-time" from 30 to 115milliseconds....i found 60milliseconds right...
POSITIVE wire is the red-black wire of electric coils(R1 2000,europe)
B wire if the wire to connect to the electric coils
for all the question,don't esitate to contact me....

P.S.this circuit is a perfect copy of the POWERSHIFT2!!!!
a few dollars for build it....and 1 hour to work on it.

got real pictures of what this looks like?

here are the powershifetr,my circuit diagram is exactly the SAME!

Looks good, now what goes where for install?
