The A6060) is a generator-set controller. It is used on generator sets from Generac, including the 0940 and 0941.
Also fitted to: Generac 00940-2 / Impact-36G plus II, Generac 00941-2 / Impact-36LPG plus II.
| Symptom | Cause | Remedy |
|---|---|---|
| Engine cranks but will not start | Fuel level low | Replenish fuel supply |
| Engine does not accelerate when load is applied | Carburetor linkage sticking with throttle stuck closed | Repair sticking throttle |
| Engine shuts down under load | Oil pressure low | See Section 5.1, ENGINE OIL SYSTEM |
| Engine speed and AC output voltage erratic under constant load. AC output does not turn off intermittently | Stepper Motor failure | Replace Stepper Motor |
| Engine speed is maintained and no-load voltage is good. However, when load is applied output voltage drops | Carburetor linkage sticking with throttle partly open | Repair sticking throttle |
| Engine starts but Stepper Motor does not move. Shut down occurs after several seconds | Stator Timing winding is open | Repair/replace bad wire(s) TIM1/TIM2 or replace Stator |
| Engine starts hard and runs rough | Badly fouled spark plug | Clean and regap or replace spark plug as necessary |
| Engine starts then shuts down after a few seconds | Oil pressure switch defective or Wire 85 circuit fault | Replace oil pressure switch if it is defective or repair Wire 85 circuit as necessary |
| Engine starts, accelerates, shuts down at 4500 rpm | Carburetor linkage sticking with throttle stuck open | Repair sticking throttle |
| Engine will not crank | Blown 7.5 amp fuse | Replace the fuse |
| Generator circuit breaker trips / no AC voltage | Short circuit on the AC output side | Locate and repair short circuit |
| Generator doesn't pull full load | Carburetion problem | Adjust or repair carburetor or fuel system as necessary |
| Generator loses AC power then shuts down | Inverter overheat condition | Allow inverter to cool; check for cause of overheating |
| No AC output | Short circuit on the AC output side | Locate and repair short circuit |
| Overvoltage condition and speed control system cannot reduce output voltage | Carburetor linkage sticking with throttle stuck partly open | Repair sticking throttle |
| Priming function does not work | Blown 7.5 amp fuse | Replace the fuse |
| The engine runs for about 10 seconds and then stops after a restart following a low oil pressure shutdown. | Low oil level was not corrected. | |
| The engine shuts down by itself. | Oil pressure is too low. | Check the engine oil level. |
| The engine shuts down due to high temperature. | Engine temperature exceeds the preset temperature. | |
| The engine speed is increased beyond the control of the computer control system. | Do not attempt to physically adjust or control the engine speed. | |
| The generator voltage output drops below a preset level. | Once the unit has shutdown, the computer is automatically reset when you restart the engine. |
