Re: 1983 50 hp Johnson Rectifier test results

This rang two bells… One where I had been working to "reverse engineer" an airguide tachometer transmitter and I had done resistance measurements on what turned out to be a (germanium) diode (rectifier) bridge: Some measurements will send current through two diodes, so you get twice the voltage drop (resistance).

The other was reading about car alternators being three-phase, and having six diodes:

I wonder/suspect the three yellow wires are from three different coils in the alternator?
