| Item | Spec | Capacity | Part # | Interval | |
|---|---|---|---|---|---|
| Air filter | filter in a suitable solvent and reinstall (see Figure 25) | — | find | ||
| Fuel filter | Replace spark plugs every 250 hours. A badly leaded plug will cause misfiring, poor operation or stopping when a load is applied. | — | 250 hr | find | |
| Oil filter | — | find | |||
| Belt | Improper belt tension will result in a slipping or broken belt. This in turn will result in overheating of the engine caused by reduced coolant flow. | — | find | ||

| e008 | No specific name provided for e008 |
| 10 | Overload |
Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| NO AC VOLTAGE | Blown fuse or circuit breaker (if used) | Look for cause and repair. Then replace fuse or reset breaker. |
| LOW AC OUTPUT | External short circuit on line | Locate and eliminate short circuit problem. |
| NOISY GENERATOR | Defective bearing in end bell | Replace bearing. |
| GENERATOR OVERHEATS | Generator overloaded | Remove part of load. |
| Engine does not crank. | 1. Check battery. 2. Are battery cables tight? 3. Is battery voltage present between control TB1 terminal 3 and B+ terminal when start switch S1 is pushed to “START?” 4. Replace start-stop switch S1 if necessary. 5. Is battery voltage present between start solenoid terminal S1 and ground when start switch S1 is pushed to “START?” 6. Replace start solenoid K1 which is defective. | |
| Engine cranks but does not start. | 1. Is battery voltage present between stop relay K2 terminal 5 and a good ground when start switch is pushed to “START?” 2. Check wiring to stop relay K2 and connections. 3. Replace stop relay if necessary. 4. Does unit have fuel solenoid? 5. Does fuel solenoid operate when start switch is pressed to “START?” 6. Check wires to fuel solenoid, check solenoid, and replace if necessary. | |
| Engine starts but stops when start switch is released. | Connect a DC voltmeter to start solenoid relay K1 terminal S1, and to a good ground. Crank the engine until it starts, release start switch and note voltmeter. Did voltme- meter indicate a voltage after start switch was released? Check wire connections from generator to start solenoid K1 terminal S1. If OK, perform generator test Generator Troubleshooting and Procedures). Check resistor R1 and resistor connections. Are they OK? Replace resistor or wire leads as necessary. Check reverse current diode CR1 for short or open, and diode connections. Replace if necessary. | |
| Generator set is running-then stops. | Press start switch S1 to “START”. Did engine start but stop when switch Sl is released? Connect a DC voltmeter between stop relay K2 terminal 5 and a good ground. (Open control cover.) Is battery voltage present when start switch is pushed to “START?” Jumper stop relay terminals 5 and 11. Crank the engine. Does engine start and run? Stop the engine. Jumper battery positive to stop relay K2 terminal 9. Does stop relay operate? Replace stop relay K2. Check resistor R1 and resistor connections. Are they OK? Repair wire leads or replace resistor as necessary. Perform generator tests (See Generator Troubleshooting and Procedures). | |
| Low battery - no charge rate. | Jumper two-step voltage regulator relay terminals “BAT” and “B’. Start generator set. (Open control cover.) Does ammeter indicate higher charge rate? Replace two-step voltage regulator relay K3. Check resistor R2, resistor connections, and replace if necessary. | |
| NO AC OUTPUT VOLTAGE | . Disconnected wire or lead on brushes. . Brushes not making contact with collector rings. . Defective bridge rectifier. . Loose wire to bridge rectifier. . Open, grounded or short circuit in shunt field or armature winding. | . Reconnect wire, or wires. . Check brush springs for free movement, or brushes which may be excessively worn. . Replace bridge rectifier, or contact Onan dealer. . Replace wire. . Test with ohmmeter, or contact Onan dealer. |
| LOW AC OUTPUT VOLTAGE | . External short circuit on line. . Generator overloaded. . Shorted or grounded circuit in field or armature winding. | . Locate and eliminate short circuit problem. . Remove part of load. . Test with ohmmeter, or contact Onan dealer. |
