- 19 - 5-4 OIL SENSOR 5-4-1 DESCRIPTION * The oil sensor mainly functions to detect posi- tion of the surface of engine oil in the crankcase of engines for general use and to stop the en- gine automatically when the oil level goes down below the lower limit specified. This prevents sei- zure of engine from occurring due to insufficient amount of oi[...]

- 20 - [Judgement of oil level] When sufficient oil is in the crankcase, both of inner and outer electrodes are immersed in the oil through which current flows across the electrodes. The sensor judges that oil in the crankcase is suf ficient. When oil level goes down and the inner electrode is exposed to the air due to consumption of oil, no curren[...]

Therefore, if no resistance reading [...]

- 35 - * If such an instrument is unavailable, the condenser can be checked by replacing with a new one. If the generator performs good with new condenser , the cause of trouble is defect in original condenser . 9-7 DIODE RECTIFIER Circuit inside of the diode rectifiers is as shown in Fig. 9-7. Check continuity between each terminal by using a circ[...]

- 36 - * Checking table for digital circuit tester .

- 70 - Circuit inside of the diode rectifiers is as shown in Fig. 2-13. Check continuity between each terminal by using a circuit tester as shown in Fig. 2-14. The rectifier is normal when condtinuity is as follows: * Checking table for analogue circuit tester . Fig. 2-13 Fig. 2-14 r e t s e t t i u c r i c e u g o l a n A r e t s e t t i u c r i c[...]

- 71 - 2-4-6 CHECK THE DC COIL Check the resistance between two brown leads from stator with a circuit tester . If the resistance reading is much larger or smaller than the specified value, the DC coil of the stator is faulty . Replace stator with a new one. 2-5 IDLE CONTROL (OPTIONAL EQUIPMENT) 2-5-1 ENGINE SPEED IS NOT INCREASED WHEN A LOAD IS AP[...]

- 72 - (4) Check the wiring through ZCT on the IDLE CONTROL UNIT . * Single V oltage T ype Make sure that an output wire from main coil is passing through the ZCT on the IDLE CONTROL UNIT . * Dual V oltage T ype Check that two output wires (black wire and red wire) from main coils are passing through the ZCT on the IDLE CONTROL UNIT in the same dir[...]

- 73 - 2-5-2 ENGINE SPEED IS NOT REDUCED WHEN LOAD IS OFF . (1) Check the distortion of the SOLENOID BRACKET as shown in step 2-5-1-(1). (2) Check the wiring of SOLENOID. Check two leads from SOLENOID are securely connected. (3) Check the wiring of IDLE CONTROL UNIT . Check all leads from IDLE CONTROL UNIT are securely and correctly connected. (4) [...]

- 74 - 3. RANGE OF APPLICA TIONS Generally , the power rating of an electrical appliance indicates the amount of work that can be done by it. The electric power required for operating an electrical appliance is not always equal to the output watt- age of the appliance. The electrical appliances generally have a label showing their rated voltage, fr[...]

- 75 - (5) Appliances without any indication as to power consumption Some appliances have no indication as to power consumption; but instead the work load (output) is indicated. In such a case, power consumption is to be worked out according to the numerical formula mentioned below . Efficiencies of some electrical appliances are as follows : Singl[...]

- 76 - NOTES : Wiring between generator and electrical appliances 1. Allowable current of cable Use a cable with an allowable current that is higher than the rated input current of the load (electrical appliance). If the input current is higher than the allowable current of the cable used, the cable will become excessively heated and deteriorate th[...]
