PROCEDURE

For Codes 11199 and 11408

1.Place the run/stop switch in the “RUN” position and within 30 seconds, check for 11 to 13 VDC between terminal J31-9 (+) and terminal B-1 (-).

2.Check for battery voltage between terminal J31-1

(+) and terminal B-1 (-).

3.Check for positive battery voltage between the ter- minal where lead 212F connects to the engine tem- perature switch and a good chassis ground. See the wiring diagram.

If the correct voltage is present for tests #1 and #2, check the wiring and connections between the PC board, the primary solenoid, and the fuel pump. See wiring diagram.

If no voltage is present for tests #1 and #2, check the run/stop switch and all wiring and connections between terminal J31-1 and the positive battery terminal. Check all the wiring and connections between Terminal B-1 and the negative battery terminal. See wiring diagram.

If the correct voltage is not present for test #3, check the wiring between the engine temperature switch and run/stop switch.

If the correct voltage is present for test #2, but not for test #1, and the voltage reading was taken within 30 seconds of placing the run/stop switch in the “run” posi- tion, The PC board is faulty and should be replaced.

NOTE: The fuel solenoids, temperature switch and the fuel pump are part of the Perkins engine and should be tested and, if necessary, repaired or replaced by a qualified Perkins engine techni- cian. To help in precisely identifying a fuel sys- tem failure, approximate solenoid resistance values and current draw for the fuel pump are included on the machine schematic.
