Hello,
I'm working on my SFC 1000. I'm going to make a new separate ignition harness that suits for BTZ and as a new feature for Ignitech also. The reason for this is that the original harness is sometimes still cutting the ignition off when getting wet even half of the wires and connectors are replaced and everything other checked, other connectors cleaned and tightened etc. Only possible next step with the original harness would be to take the whole harness of the bike and open it which I'm not going to do now. The problem is gone everytime before I have a voltmeter to locate it.
I turned the engine using the starter motor while there was an oscilloscope wired to one pick-up at time, BTZ connectors off and no gasoline. The pick-up wires are replaced some years ago with black silicone cable, so I can't have a clue which one has a black mark. All of them are in a non-standard water proof connector block in a row 1+, 1-, 2+, 2-, 3+, 3-. The number means cylinder numbering and the polarity means the pick-up gives positive voltage swing when the lobe is going closer to pick-up and negative when going away from pick-up.
Which one of the pins on the BTZ unit is positive and which one is negative? On the BTZ connector the other row there are pin1 that is empty, pin2 (on the center) and pin3 (on side)are for pick-ups. Those were connected that the plus were on the pin3 (on side) and the minus was in the pin2 (center). If this is correct, the Ignitech adapter wiring (from Ignitech) gives negative polarity for TCIP4 inputs, but it can be inverted on the software.
The advance have been correct and the marks almost perfectly inline when idling. When revving the advance have never reached the mark where it should be according to the service manual, far too less advance. I don't know have the pick-ups been in correct or reversed polarity.
I know I can try both polarities, but I'm not shure does it still indicate clearly for the correct polarity.
