Killing Dist pickups ?

Sounds like other problem. Pista provided info on how to test with meter. Too many loads on pickup signal reduce its output. Output increases with engine speed, cranking speed is about 200 RPM at best, at 2000 the output is 10x. Most pickup issues happen when starting. A relay could be cobbled in for all the rev limter stuff, to switch in after start. Or make an amp to boost signal, or make or buy a decent optical or Hall triggered distributor.
