I bought a Project HG that came with an Altek MPU. I had a weird problem with coils firing twice at the same time that I managed to fix in repining the connectors. I also installed a brand new rectifier board and a new altek solenoid board
Now, everything work as it should except the right gate. The right gate coil has been replaced and still nothing..
In test mode, all the coils are firing one by one as it should except coil #13 (right gate). If I look at the leds on the new SDB during test mode, each led blink one by one when their respective coil fires..but again, nothing for Q17.
I checked the continuity on both the daisy chain and from the ground lug and the pin on the J5 connector and the continuity is good.
Since the right gate signal should come from the mpu and that my SDB doesn't seems to react, I suspect a communication issue between the mpu and the SDB but just don't know where to start.
Does anyone of you have a clue on which pin or connector should I check first? Any advice?
