Hi everyone. I've got a bitsa Casa 186 engine I've built up for a mate that's running on an Li crankshaft. It's never going to anywhere other than pottering around town so I'm willing to chance the weaker crank. My issue is that whatever electronic ignition system I fit I get no spark. I tried a Motoplat setup first which was dead in every respect once I found out how to test it, and I'm now using a new Indian stator with an Indian flywheel and a known to be good CDI. I'm using a test bed to kick the engine over but I get nothing. I know the stator is good as I've tested it already. I've connected the red and white wires to from the stator to the corresponding terminals on the CDI, and the yellow wire from the CDI is connected back to earth on the engine case. The plug is obviously held to earth on the case also. Everything has been swapped out, i.e. CDI, HT lead and plug but to no avail- I still have no spark. I've disconnected the green wire from the on/off switch on the test bed in case that was faulty, but it still makes no difference.
The only thing I can think of is that maybe the pickup isn't at the same level as the prongs on the flywheel magnets? But before I start tearing it apart again has anyone got any suggestions as to what else could be causing the problem? Is there something obvious I've missed?
