Trying to diagnose an engine that runs OK in the back yard, but has ignition problems at higher RPM's. I'm reading the troubleshooting guide from CDI Electronics (see link below). It reads
"HIGH SPEED MISS:
1. Using the CDI meter with the 511-9773 peak reading adapter, (or CD-77) and 511-9770 piercing probes, DVA check stator voltage to each pack
at high speed. If it exceeds 400 volts, replace the pack."
I have piercing probes already. I can get my hands on a DVA multimeter. But I don't understand why I need to use the piercing probes. If I am checking the voltage "at high speed", obviously the engine is running.... so why can't I just measure the voltage at the screw posts where the stator wires connect to the CDI wires?
