TEST PROCEDURE				6.
1.	Turn the engine off.
2.	Open the right side engine service access
3.	door.
	Locate the fuel solenoid, located on top of
4.	the engine.
	Locate and unplug harness connection P/J
	73. Cut any necessary cable ties.		See
5.	Figure F.4. See Wiring Diagram.
	Using the Ohmmeter, check the pull-in coil
	resistance, (black wire to white wire). The
	normal resistance is less than 0.5 ohms.
	Check the hold-in coil resistance, (black
	wire to red wire). The normal resistance is
	approximately 11 ohms.	Check the
	Resistance between the black wire and a
	clean, unpainted chassis ground. The
	resistance should be very high, 500,000
	Ohms or more. If any of the above resis-
	tance values are incorrect, the solenoid			7.
	may be faulty. Replace.

RANGER 305D

Using an external 12VDC supply, apply voltage to the pull-in coil leads, (black-) to (white+). The solenoid should activate. REMOVE THE VOLTAGE immediately to avoid damaging the solenoid.

Apply 12VDC to the hold coil, leads, (black-) to (red+) While the voltage is applied, manually move the solenoid to the fuel on position. The solenoid plunger should hold this position until the voltage is removed.

If either coil does not operate as described, check for mechanical restric- tions or other problems with the linkage. If the linkage is intact and the solenoid does not operate correctly when 12VDC is applied, the solenoid may be defective. Replace.

Re-connect fuel solenoid and replace any previously removed cable ties.

If finished testing, close the engine ser- vice access doors.
