I have an MSD MC2 motorcycle ignition box. Some say that I need a Hall Effect trigger to make it spark. I did have an MC3 hooked up to my 1989 Suzuki GSXR 750. I did have it hooked up to the oem neg wire for the triggering ,that came from the oem ignitor, the box where the oem pickup wires go to, and where the neg coil wires come out from. My ignitor (transistorized) went out and I want to know how to determine if the MC2 box will trigger off of the magnetic pickup or do I need to change it out and install a Hall Effect pickup.
