center of the front frame member (Fig. 20).
1. Center of Front Frame Member
Note: Lock both brake pedals together before
towing.
3. Attach the other end of the towing device to a
vehicle that is capable of towing the machine
safely at speeds below 16 kmh (10 mph).
4. An operator must be on the machine to steer it
and keep the traction pedal fully depressed in
the forward position while towing.
5. When towing is completed, reinstall the drive
shaft as shown in Figure 19. (The splines are
designed to allow assembly only when the two
halves of the shaft are properly oriented.)
DIAGNOSTIC LIGHT (Fig. 21)
The RM 5300-D is equipped with a diagnostic light
which indicates if the electronic controller is func-
tioning correctly. The green diagnostic light is locat-
ed under the control panel, next to the fuse block.
When the electronic controller is functioning correct-
ly and the key switch is moved to the ON position,
the controller diagnostic light will be illuminated.
The light will blink if the controller detects a mal-
function in the electrical system. The light will stop
blinking and automatically reset when the key switch
is turned to the OFF position.

1. Electron~ Controller Light
When the controller diagnostic light blinks, one of
the following problems has been detected by the con-
troller:
1. One of the outputs has been shorted.
2. One of the outputs is open circuited.
Using the diagnostic display, determine which output
is malfunctioning; refer to Checking Interlock
Switches.
If the diagnostic light is not illuminated when the
key switch is in the ON position, this indicates that
the electronic controller is not operating. Possible
causes are:
1. Loopback is not connected.
2. The light is burned out.
3. Fuses are blown.
4. Not functioning correctly.
Check electrical connections, input fuses and the
diagnostic light bulb to determine malfunction. Make
sure the loopback connector is secured to the wire
harness connector.
DIAGNOSTIC ACE DISPLAY
The RM 5300-D is equipped with an electronic con-
troller that controls most machine functions. The
controller determines what function is required for
various input switches (i.e., seat switch, key switch,
etc.) and turns on the outputs to actuate solenoids or
relays for the requested machine function.
For the electronic controller to control the machine
as desired, each of the input switches, output sole-
noids and relays must be connected and functioning
