Been running the same alt in my EZ for 19 years still putting out 14.1 volts, One wire.

Do you want an internally-regulated alternator? Bob Nuckolls does not recommend them because they don’t incorporate crowbar overvoltage protection. See www.aeroelectric.com/articles “The truth about crowbar OV protection"
Anyway, IG must receive 12V to power the field windings. No power to the field = no output, “S” Sense must be connected near the battery to vary the voltage output for the load.
It is not much work to convert a Denso to external regulation. Here is one way. There are a couple more ways to do it. https://www.canardzone.com/forums/topic/18661-kents-long-ez-project/?do=findComment&comment=61828

Mine has the 3 terminals but I assumed only the "batt" was an active terminal. Out of desperation today, I added a wire from the "IG" term. to the master solonoid Will test tommorow. If that doesnt work I am off to NAPA.
