REAR MUDGUARD - EXHAUST PIPE 19
NEUTRAL SWITCH
Disconnect the neutral switch connector.
Check for continuity between the wire and ground for each gear selection.
The switch is working properly when there is continuity in the neutral
position and no continuity in any other gear.
TEMPERATURE INDICATOR
Disconnect the wire from the temperature sensor and ground it.
Turn the ignition switch to "ON" the needle on the temperature indicator
must move to the "H" side (red). Don't ground the temperature sensor
wire for more than a few seconds or there may be damage to the gauge.
OIL PRESSURE SENSOR
Disconnect the oil pressure sensor wire.
Turn the ignition switch to "ON".
Ground the sensor wire to the engine; the low oil pressure indicator
should turn on. If not, check for a short or disconnected wire or that the
warning light bulb is not burned; replace bulb if necessary.
If the sensor, with switch in "ON" position and engine at stop, does not
show any continuity between main wire and ground, it should be replaced.
RESERVE FUEL INDICATOR
Remove the reserve fuel sensor from the tank.
Move the float towards the threaded part of the sensor and connect the
two wire terminals to a tester.
There must be continuity.
THERMOSWITCH
The cooling fan motor is operated by a thermoswitch mounted on the
radiator. If the fan doesn't start, link with a spare wire, the linkage of the
two wires connected to the switch.
Turn ignition to "ON" , the fan motor must turn. If it doesn't, check battery
voltage between the connector and ground (ignition switch must be "ON")
If there is no voltage, check for a burned or defective fuse, or for a
disconnected or shorted connector.
