FUEL PUMP
SYSTEM INSPECTION
Turn the ignition switch OFF. Remove the seat and disconnect
the fuel pump relay wire connectors. Short the black and
black/blue wire teminals with a jumper wire.

Gasoline is extremely flammable and is explosive under certain
conditions. Work in a well ventilated area with the engine
stopped. Do not smoke or allow flames or sparks in the work
area or where gasoline is stored.
Turn the ignition switch ON and let fuel flow into the beaker
for 5 seconds, then turn the ignition switch OFF.
Multiply the amount in the beaker by 12 to determine the fuel
pump flow capacity per minute.
FUEL PUMP FLOW CAPACITY:
600 cc (0.630 US qt 0.528 Imp qt)/minute at 10 V
OIL PRESSURE SWITCH

Disconnect the oil pressure switch wire from the switch by re-
moving the terminal screw. Short it to ground using a jumper
wire.
Turn the ignition switch "ON".
The oil pressure warning light should come on.
If the light does not come on, check the bulb, sub-fuse (10 A)
and wires for a loose connection or an open circuit.
Start the engine and make sure that the light goes out. If the
light does not go out, check the oil pressure (page 2-41-
If the oil pressure is normal, replace the oil pressure switch.

nector.
Check the neutral switch for continuity between the light
