The No-fuse Breaker is a generator-set controller. It is used on generator sets from Cummins/Onan, including the P3200i and P4300i.
| Symptom | Remedy |
|---|---|
| When Engine Fails to Start | Check if the DC circuit breaker is turned OFF. Check if the 'O_Lod' (overload) is indicated in the Multi Monitor. Check AC receptacle and DC terminals for loose connection. Check to see if engine starting was attempted with appliances already connected to generator. Depress the circuit breaker into ON position, after making sure the charging current level is proper and the battery is in the normal condition. Stop the engine and check the appliance and/or generator for overloading. Secure connection if necessary. |
| When No Electricity Is Generated at Receptacle | Check fuel level. Check to make sure generator is not connected to an appliance. Check spark plug for loose spark plug cap. Check spark plug for contamination. Check engine oil level. Check if the recommended spark plug would be adopted. If empty, refill fuel tank making sure not to overfill. If connected, turn off the power switch on the connected appliance and unplug. If loose, push spark plug cap back into place. Remove spark plug and clean electrode. If the engine oil level is low, add the oil to the upper level line on the oil gauge. If not, replace with the recommended spark plug. If the recommended spark plug is not available by all means, make sure to replace with equivalent one of resistance type. |
