Replace AVR
With engine stopped, replace AVR with a
new AVR. Start engine and adjust trimmer
on back of AVR. Test terminal voltage.
Voltage should be between 95-135V. If
voltage is met, original AVR is not adjusted
properly or faulty. Replace as necessary. If
voltage not met, check circuit breakers and
receptacles.
