IMPORTANT: Running the engine with the by-pass valve open
will cause the transmission to overheat.
DIAGNOSTIC LIGHT (Fig. 19)
The RM 6500-D is equipped with a diagnostic light which indicates
whether or not the electronic controller is functioning correctly. The
diagnostic light is located on the steering tower panel. When the
electronic controller is functioning correctly and the key switch is
moved to the ON position, the controller diagnostic light will be
illuminated for approximately 6 seconds. The light will not illumi-
nate if the controller detects a malfunction in the electrical system.
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 connector (under control panel cover) is not con-
nected.
2.
The electronic controller light is burned out.
3.
Fuses are blown.
4.
The light is 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 6500-D is equipped with an electronic controller which
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 solenoids and relays must be connect-
ed and functioning properly.
The Diagnostic ACE display is a tool to help the user verify correct
electrical functions of the machine.
