1. Measure the voltage at the

battery while cranking.

2. Momentarily connect Terminals A and F. The

actuator should move to the full fuel position.

1. Measure the actuator output, Terminals A & B,

while running under governor control.

If unsuccessful in solving instability, contact GAC for assistance.

If the voltage is less than:

a. 7 V for a 12 V system, or

b. 14 V for a 24 V system,

Then: 1. Check wiring

2. Check circuit protection/relay

3. Check charging system

4. Check battery

Actuator or battery wiring in error

Actuator or linkage binding

Defective actuator

Fuse open. Check for short in actuator or harness.

Check START FUEL and CRANK

If voltage measurement is within 2 V DC of the battery supply

voltage level, then fuel control is restricted from reaching full

fuel position, possibly due to mechanical governor, carburetor

spring, or linkage interference.

Check SPEED, IDLE, GAIN, START FUEL, and CRANK
