Fuel Injector Test
NOTE: The harness connector and locking spring is
bonded to the fuel injectors with an epoxy. DO NOT
attempt to disconnect the connector from the fuel
injectors. Damage will occur to the injector and/or
harness if attempting to separate at that location.
Separate the fuel injector from the vehicle harness
as shown in the illustration below.
IMPORTANT: Take note of PTO and MAG fuel injector
ha
rness connectors before disconnecting them. The
harnesses are different and
can not be connected
incorrectly (PTO - Gray; MAG - Black).
The fuel injectors are non-serviceable. If diagnosis
in
dicates a problem with either injector, test the resistance
of the fuel injector(s) by measuring between the two
harness pin terminals:
NOTE: Be sure to connect like colored fuel injector
c
onnectors for proper engine function (PTO = GRAY,
MAG = BLACK).
