I'm reading 13.8 eis voltage. I have the EFIS alarm set at 12 volts. Today at 6500 ft. 72 degrees OAT. The EFIS voltage would vary between 11.8 and 12.3 and set the alarm off. Odessie680 battery, Plan Power alternator. Is this normal? Could it be the voltage regulator? The Odessie battery is 2 years and 300 hours old. Any ideas are appreciated.
Thanks,
Fred
