MattS Posted February 28, 2010 Report Posted February 28, 2010 I was getting high voltage reading a few weeks ago before my aircraft went into a pre-buy. The buyer walked away, but the mechanic said I needed a new voltage regulator and battery. I do the work and everything is working just fine. I go on a flight today and my high voltage light flashes intermittently... What is the deal?
Piloto Posted February 28, 2010 Report Posted February 28, 2010 Underneath the instrument panel on the passenger side there is a 3" x 3" aluminum box with two adjusting holes on the bottom side. This is the voltage regulator. One of the holes is for voltage limiting and the other for voltage setting VDC. Connect a digital voltmeter to the cigarette lighter. While in flight after 15 minutes adjust the VDC to read 14.0 volts on the digital voltmeter. This should clear the warning light problem. If the voltage setting is set too close to 15V the light will not blink until the battery is charged thus causing and increase in voltage. José
