Symptoms & remedies

SymptomCauseRemedy
Engine Does Not Crank1. Open control fuse F1. 2a. Check condition of battery and recharge or replace. a. Battery not charged. 2b. Clean and tighten all connections at battery, K1 start solenoid, and starter motor. b. Battery connections loose or dirty. c. Battery cable size too small. 3. Start solenoid (K1) not energized 3a. Check wiring continuity to the start solenoid (K1) coil from control assembly (A1) and from ground to start solenoid (K1). a. Open circuit to start solenoid coil. b. Defective start solenoid coil. 3b. Test start solenoid (K1). 3c. Test Start/Stop switch (S1). 3d. Measure voltage between start solenoid terminal I and ground with switch (S1) held in the Start position. If voltage is not present and continuity and battery check OK, control assembly (A1) is defective.
Engine Cranks But Does Not Start4a. Check continuity between starter lead on start solenoid (S1) and ground. a. Open circuit to starter (B1). b. Open circuit between battery (B+) and the start solenoid contact (BAT). c. Defective start solenoid (K1). 4b. Measure voltage between starter terminal and ground with switch (S1) held in the Start position. If voltage is not present and continuity checks OK, start solenoid (K1) is defective. 4c. If voltage is present in step 4b, starter (B1) is defective.
Engine Cranks from Set but Not from Remote Control Panel5a. Check wiring continuity between control assembly (A1) and remote Start/Stop switch. a. Open circuit between control assy. (A1) and remote Start/Stop switch. b. Remote Start/Stop switch faulty.
Engine Starts But Stops2. Defective low oil level switch.2. Disconnect low oil level switch and check set operation. Replace if defective.
Engine Starts, Then Stops3. No field flash voltage due to:3a. Check wiring continuity to the brush block F1-F2, voltage regulator VR1, control assembly A1 and generator B1-B2 and 01-02 windings. Check connections of P5 and P6 connectors on the generator housing. 3b. Check brushes for wear and for contact with the slip rings. 3c. Check slip rings
Remote Run Lamp Does Not Illuminate5. If remote switch functions properly for starting and stopping genset but meters and run lamp do not operate, and step 1 checks OK, control assy. (A1) defective.If voltage is not present, replace control assembly (A1). If voltage is present, check continuity of remote control wiring.
Too Much DC Load6. Turn off the genset, disconnect the remote control, and check for shorts or too many remote accessories.
