Tests
Indicator light must be ON indicating there is continuity
in the wiring harness and there is a signal from engine
and pump controller.
6. Start engine.
7. Actuate propel function.
8. Turn propel speed switch to fast speed (rabbit).
The brightness of indicator light must increase slightly
while propelling in fast speed.
If light goes OUT or brightness does not increase,
check wiring harnesses, solenoid coil, propel pressure
switch, pump pressure, and pump control valve
pressure sensors. (See procedure in Group 9015-15.)
NOTE: No dig functions can be actuated. The dig
pressure switch must be OFF so it does not send
an electrical signal to engine and pump controller.
