Electrical System (Rev. C)
Using the ACEt Diagnostic Display
The primary electronic controller controls most machine
functions. The controllerdetermines what function is re-
quired for various input switches (i.e. seat sensor, key
switch, etc.) and energizes the outputs to actuate sole-
noids or relays for the requested machine function.
For the electronic controller to control the machine as
desired, each of the inputs, outputs must be connected
andfunctioningproperly.Theprimaryelectronicc ontrol-
ler controls the functions of cutting units #1 through 5.
On the RM 6700-D, the secondary electronic controller
controls the functions of cutting units #6 and #7.
The Diagnostic ACE display is a tool to help the user
verify correct electrical functions of the inputs and out-
puts used and controlled by the electronic controllers.
Checking Interlock Switches
The purpose of the interlock switches is to prevent the
engine from cranking or startingunless the traction ped-
al is in NEUTRAL, the Enable/Disable switch is in DIS-
ABLE and the Lower Mow/Raisec ontrol is in theneutral
position. The engine will stop when the traction pedal is
depressed with operatoroff the seat.In addition,the en-
gine will stop if the traction pedal is depressed and the
parking brake is engaged.
CAUTION
The interlock switches are for the protection of
the operator and bystanders and t o ensure cor-
rect operation of the machine. Do not bypass or
disconnect switches. Check operation of the
switches daily to make surethe interlock system
is operating properly. If a switch is defective, re-
place it before operating. Do not rely on safety
switches entirely - use common sense!
Check Input & Output Functions
1. Park machine on a level surface, lower the cutting
units, stop the engine, and engage the parking brake.
2. Open control panel cover.
A. For RM 6500-D: Locate wire harness with
Loop-back connector labeled #1 for electronic
controller.
Note: For checking optionalTurfDefenderleakde-
tector, see Leak Detector Operation and Checking
Leak Detector Operation inthis s ection ofthis manu-
al.

Carefully unplug loop back connector from harness
connector.
Connect the Diagnostic ACE display connector to
the harness connector. RM 6500-D overlay decal
specific to the model and serial number of the unit
being tested must be placed on the diagnostic tool.
B. For R M-6700-D: Locate wire harness and con-
nectors labeled #1 (primary electronic controller) or
#2 (secondary electronic controller).
Note: For checking optionalTurfDefenderleakde-
tector, see Leak Detector Operation and Checking
Leak Detector Operation inthis s ection ofthis manu-
al.
Carefully unplug loop-back connector from harness
connectors.
Connect the Diagnostic ACE display connector to
the correct harness connector. RM 6700-D overlay
decals specific to the model and serialnumber ofthe
unit being tested must be placed on the diagnostic
tool. Overlay decal #1 must be used when checking
primary controller (connector #1) and overlay decal
#2 must be used when checking secondary control-
ler (connector #2).
2. Turn the key switch to the ON position, but do not
start machine.
Note: The red text on the overlay decal refers to input
switches and the green text refers to outputs.
