TEST PROCEDURE 29 – 12-Volt Accessory Receptacle
See General Warnings, Section 1, Page 1-2.
NOTE:
Keep the battery connected during this test procedure.
1.
Disable the vehicle.
See Disabling the Vehicle on page 1-3.
2.
Set the multimeter to 20 VDC.
3.
Measure the voltage between the center contact and the outer contact of the accessory receptacle. The voltage
should be approximately 12 VDC.
4.
If the voltage is not approximately 12 VDC, check the 10-amp fuse on the orange/white wire (w115) located on the
electrical component mounting plate.
See Test Procedure 2 – Fuse on page 11-11.
5.
If the fuse is good, check the continuity of the wires connected to the accessory receptacle.
6.
If the wire continuity is good, replace the accessory receptacle.

performing this test procedure.
1.
Disconnect battery and spark plug wire(s).
See Disconnecting the Battery – Gasoline/Diesel Vehicles on
2.
Disconnect the orange wire from the center post of the fuel level sending unit.
3.
With a multimeter set to 2k ohms, place the red (+) probe on the center post of the sending unit. Place the black
(–) probe on the ground connection of the sending unit
.

4.
The following resistance readings (in ohms) should be indicated, depending on the position of the float inside
the fuel tank. The resistance reading will vary according to the exact position of the float. The following table
may be used as a guideline to determine if the fuel level sending unit is operating correctly. Make sure the float
is at the surface of the fuel in the tank.
