voltage regulator questions

The resting voltage of a fully charged EarthX battery is 13.3 volts.

From EarthX tech support.

“I still think your charging system is not working properly. Our battery should be in the 13.8 - 14.5 volt range when the charging system is working”. 

I measured 3.3 while the engine was running. 

Hi Walt! Do you know what causes the 12-14Ah discharge which appears rather high to me. Has this been the normal level of current draw over the years or is that a recent matter? The installations I happen to know range between 6 and 8Ah. Perhaps you are looking for something else but a faulty voltage regulator.

For better understanding, what the battery voltage towards the end of a flight „in flight“ (whilst the VR is supposed to charge, engine loud) and on ground with the engine quiet and power consuming gadgets being on (as in flight)? And what Amp-readings do you get for both?

SH have upgraded their VR some time in the past when the lighter battery technology with higher Voltage levels reached the fields to suit their charging characteristics better. Which VR (product no.) do you use?

I think 14A is about right. There is a Skyview Touch, Garmin 696, each has their own GPS and A-DSB, nav lights, cooling fans, GRT-200 radio, it adds up. At the end of flight, engine running the amp draw is 0, the voltage is 13.3. When the engine is turned off the amp draw is -13A and vi collage is 13.2. This SH regulator has been in the plane since about 2017. 

Hi Walt,

I have just fitted a CARMO CARR5005 charging an Earth X  - It is delivering similar numbers to your Silent Hektik😈
