Guys,
I posted a message yesterday in the electrical forum. Long story short, my RV8 is indicating low voltage on my Vision Microsystem. Yesterday, my wife helped my pull my cowling off and I double-checked all connections. Everthing looked good. I then adjusted my alternator belt and made it a little tighter. I then checked the nut on the pully and it seemed to be good and tight. Anyway, I fired it up and it went to 14.2 volts with nothing on. Then, I turned on my avionics master, strobes, position lights and it dropped to 12.3 volts. When I turned my landing lights, it dropped to 12.1. My warning light came on telling me of low volts. I have a 35 amp alternator with external voltage regulator. Even when I ran it up to 1800 rpm it was still doing it.
When I turned off my landing lights, then the volts go back to 12.6. I am lost at what to do next. I think my voltage regulator is working fine. It is mounted on the firewall to reduce vibration. Any thoughts or ideas would be appreciated. I am about to pull my hair out.
