What I think the problem stems from is the fact that the new cdi circuit fires as the magnet approaches the hall effect and mine fires as it leaves it. Plugging in a hall sensor to the new cdi and adding the correct wiring to provide power to the board produces nothing on the new cdi, wheras doing the same thing on mine works as expected. I have removed everything on mine that is inline with the trigger pulse from the hall and it still didn't work. Also Rob suggested using a 150 ohm resistor hooked to the led output on the timer board, but on all of mine I get no trigger pulse, no led light, no power pulse of any kind so that didn't work at all. If I directly plug a CH Synchro Spark module into mine where the Hall effect normally plugs in and add the hall to the other end of the Synchro Spark as an inbetween circuit, mine functions great.
So it is a pulse problem. Mine will trigger if I remove the hall and short my pulse wire to ground..not so with the New CDI. There is a major difference between the 2 circuits which I have to work out. Either an inverter circuit with a 7404 hex inverter chip or something else..
Wish I had a scope to trace the signals..might be the key to success.
