My Grizzly has no spark. Ignition coil ohmed out ok, as did the Generator (Pulse coil and Source coil), kill switch and main switch also checked A-OK. Before purchase a too expensive CDI (don’t understand why the 660 is a lot less, when looks more complicated) was checking wiring. The four connector from the generator to the CDI, three of the wires (red, white, and green) all go to the four connector to the CDI, but the brown wire from the generator seems to go to the eight pin connector. Have a wiring diagram, just shows the 4 wires from the pulse and source go to the CDI, but not with what connectors. Can’t find out where the fourth wire to the four wired connector to the CDI is coming from. Wiring colors are somewhat hard to make out with 100% accuracy. Is this right? Thanks
