Multiquip Portable Generator DCA40SSKU4F2

Check for rusted, corroded and oxidized electrical connections

Check for carbon flash deposits around the 120/240V AC receptacles

Check for signs of wire overheating

Check for infestation inside the generator

Check for elongation on the bolt hole opening on the buss bar

Check if electrical connectors are seated correctly

Check for loose crimp connections

NOTICE: The GFCI receptacle is designed to interrupt power when a ground fault exists to prevent injuries and shock hazards. DO NOT use the GFCI receptacle if the test below fails. Consult a qualified electrician for repair or replacement of the GFCI receptacle. Test the GFCI receptacle at least once a month.

Start the generator as outlined in the start-up procedure in this manual.

Place a GFCI circuit breaker in the ON position.

Verify that the status LED on the corresponding GFCI receptacle is ON (GREEN).

Press the TEST button on the GFCI receptacle and verify that the status LED turns OFF.

Press the RESET button to restore power to the GFCI receptacle and verify that the status LED is ON (GREEN).

If the status LED is flashing (RED), is the GFCI receptacle replaced immediately?

Air cleaner for restrictions and contaminants. Replace if necessary.

Cooling system hoses for cracks and distortions — tighten clamps or repair as needed.

Radiator for restrictions and corrosion.

Engine block heater for leaks and verify unit functioning properly. Engine block heater is an option on some units.

Coolant, fuel and oil leaks. Tighten connections or repair as needed.

Belts and pulleys for cracks and wear — adjust or repair as needed.

Governor and injection pump for leaks and proper operation.

Turbocharger for proper clearance and free movement as required. Reference engine service manual.

Fuel tank for contaminants and condensation.

NOTICE: Before performing the continuity check, both surge protector lead wires (Figure 50) must be disconnected from the rotating rectifier.

Surge protector lead wires disconnected from the rotating rectifier?

Place the selection dial on the multimeter in the Ω position.

Selection dial on the multimeter placed in the Ω position?

Next, place the multimeter leads across the surge protector as shown in Figure 50.

Upload a photo of the multimeter leads placed across the surge protector.

Multimeter displays an open circuit?

If the meter indicates continuity or another reading, replace the surge protector.

Does the meter indicate continuity or another reading?

NOTICE: Before performing the resistance test, the three yellow lead wires (Figure 37) must be disconnected from the rotating rectifier. If the reading indicates an open circuit the component may have to be replaced or repaired.

The exciter armature (Figure 37) consists of three yellow lead wires with no wire designation. These three wire leads are connected to the U, V and W terminals on the rotating rectifier.

Are the three yellow lead wires disconnected from the rotating rectifier?
