Joe,
When you conducted this test, did you have the specified capacitor installed?

As an experiment, I connected a wire from the load side of the battery contactor to terminal "C" of the Ducati regulator. I went flying. At cruise speed, I turned off the master switch which disconnected the battery from the electrical system. As expected, nothing changed. Everything electrical kept right on working. Shutting off the master switch had no affect, except for an intermittent high voltage alarm. When the alarm sounded on the D-180, I was reluctant to increase the RPM, not wanting to destroy any avionics. Back on the ground, I downloaded the Dynon D-180 data to my computer to analyze. The maximum voltage of 14.7 occurred at about 5200 RPM. The voltage fluctuated between 13.25 and 14.7
So once enabled, the Ducati regulator will remain enabled by its own output voltage. The Ducati does not need a battery to continue operating. However, a connected battery will have a stabilizing affect on system voltage. Without a battery, the system voltage varied plus or minus 3/4 of a volt or 1.5 volts total.
Based on this experiment, the Rotax charging system needs a battery for stability.

Yes, the 22,000 microfarad capacitor is soldered to Van's Control Board in my RV-12. | Quote: | When you conducted this test, did you have the specified capacitor installed? Ken
