Troubleshooting
6Symptoms & remedies
| Symptom | Remedy |
|---|---|
| The engine stops and will not restart. | Check the engine oil level (see page 40) before troubleshooting in other areas. |
| Engine speed becomes abnormal. | The engine will automatically stop if the engine speed becomes abnormal. |
| Abnormal voltage is detected during generation. | The engine will automatically stop during generation when it detects abnormal voltage. |
| When the engine will hot start | 1. Is the engine switch on? 2. Does the oil alert lamp flash when the starter is pulled? 3. Is there enough fuel? 4. Are all loads disconnected from the AC receptacles? 5. Is there a spark at the spark plug? a. Remove the spark plug cap, Clean any dust from around the spark plug base, then remove the spark plug. b. Install the spark plug in the plug cap. c. Turn the engine switch on. d. Grounding the side electrode to any engine ground, pull the recoil starter to see if sparks jump across the gap. e. If any fuel has been spilled, make sure the area is dry before testing the spark plug. Fuel vapor or spilled fuel may ignite. Perform this test in a well-ventilated area. f. If there are no sparks, replace the plug. g. If the new spark plug does not spark, take the generator to an authorized Honda dealer. |
| Occasionally you may hear a light ‘‘spark knock’’ or ‘‘pinging’’ (metallic rapping noise) while operating under heavy loads. | This is no cause for concern. If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline. If spark knock or pinging persists, see an authorized Honda generator dealer. |
| Running the engine with persistent spark knock or pinging can cause engine damage. | Running the engine with persistent spark knock or pinging is misuse, and the Distributor’s Limited Warranty does not cover parts damaged by misuse. |
