Location ID Module
ThelocationIDmoduleexistsintheelectriccuttingreels
circuit toidentify the locationof the three(3) cutting reel
motors. This module allows such machine features as
raising the centercuttingunit slightly later than thefront
cutting units. The location module plugs into the E--Re-
elswire harnessundertheleft sidecover nexttothe op-
erator seat (Fig. 82).
Testing
1. Park machine on level surface, lower cutting units,
stop engine, apply parking brake and remove key from
ignitionswitch.Removerightsidecovernexttooperator
seat to allow access to location ID module.
2. Carefully unplug wire harness connector from loca-
tion ID module connector.
NOTE: Location ID module connector terminals A and
B are not used on Greensmaster TriFlex Hybrid ma-
chines.
3. Using a multimeter, measure resistances between
module connector terminals as follows (Fig. 83):
A. Verify that resistance between connector termi-
nals C and F is approximately 6.2K ohms. Record
measured resistance.
B. Verify that resistance between connector termi-
nals D and F is approximately 3.9K ohms. Record
measured resistance.
C. Verify that resistance between connector termi-
nals E and F is approximately 1.6K ohms. Record
measured resistance.
D. If any of the measured resistances vary by more
than 10%, replace location ID module.
4. After testing is completed,secure wire harness con-
nector tolocation IDmodule connector.Install rightside
cover next to operator seat.
