3) Checking to be done when the lamps do not light up
Check the charge lamp and oil lamp when the engine is stopped, and check the fuel lamp after depleting the
fuel tank to see if the bulb of the lamp is dead. In addition, check to see it voltage is applied to every coupler
of the lamps.
When voltage is not
applied
(Charge lamp)
(Oil lamp)
(Fuel lamp)
(Stop status)
(Start status)
1. Regulator is defective.
2. Poor contact of couplers, wires etc.
3. Wire breakage related to charge lamp
(Check the conductivity from the charge lamp up to the regulator.)
1. Fuse (5A) is blown.
(Visually check if wires are shortcircuirted.)
2. Oil switch is defective.
(Check the oil switch itself for conductivity.) (Photo 4)
3. Wire breakage related to the oil lamp
(Check the conductivity from the starter switch AC terminal up to oil switch terminal.)
1. Fuse (5A) is blown.
(Visually check if wires are shortcircuirted.)
2. Fuel sensor (thermistor) is defective.
(Measure the electric current values at the times when fuel is filled and when fuel is depleted.)
