582 Electrical Regular HELP!!
I have a Kitfox 3 with a 582 Rotax. I was flying the other eveing and lost all electrical power. I landed and the battery was dead. I replaced the battery (only 3 mos old) with a new one. With the new batterey I was generating 12.6 volts with the engine off or on. This would indicate a regular problem wouldn't it?
I ordered a new Key West Regulator (3 Phase) and installed it. I am not sure the new regulator is working. I hooked up the Ohm meter when the engine is running and I am gettingf 26.5 volts!!! Shouldn't I only be getting about 13.5 to 14 volts?
I have some other questions and could use an electrical expert ... I am not familar with elctrcial and the correct volts.

Re: Electrical Regular HELP!!
The Key West regulator works by shorting the output from generator coil.
It does this and varies the duty cycle to maintain a charging voltage to the battery much like a switch mode power supply. I had one on my 582. It is noisy. One thing you can do to help is to put a large capacitor (500 uF, 25V) on the output. Then measure the output voltage.
You didn't measure that high voltage across the 12V battery??
