COOLANT REQUIREMENTS
Antifreeze should be used during all seasons to protect
the engine cooling system from corrosion as well as
freezing damage.
The cooling system of the engine has been filled at the
factory with a 50% water and 50% ethylene-glycol
antifreeze mixture. This mixture provides protection to -
34 degrees F. Never exceed a 50/50 antifreeze/water mix
ratio and never use 100% antifreeze for makeup coolant.

BATTERY CONNECTION
INSTRUCTIONS
The MD25 requires a customer supplied 12 volt group 26
battery with minimum 675 CCA. A battery mounting
kit has been supplied loose with the unit. When con-
necting the battery, ALWAYS CONNECT THE POSI-
TIVE CABLE FIRST and THE NEGATIVE CABLE
LAST! Disconnecting the battery is done in reverse,
disconnecting the negative cable first and then the
positive cable.
WARNING - POTENTIAL BATTERY
EXPLOSION
THIS UNIT USES A NEGATIVE GROUND. CON-
NECTING THE NEGATIVE CABLE FIRST MAKES
THE BATTERY POSITIVE TERMINAL HOT. CON-
NECTING THE POSITIVE CABLE LAST MAY RE-
SULT IN ACCIDENTAL SHORT CIRCUIT OF THE
POSITIVE BATTERY TERMINAL TO ANY OF THE
SURROUNDING METAL SURFACES. (I.E. DROP-
PING A TOOL, WRENCH SWING ETC.) USE EX-
TREME CAUTION WHENEVER MAKING OR
BREAKING THE BATTERY CONNECTIONS AND
FOLLOW THE CORRECT SEQUENCE CAREFULLY.
NEVER ATTEMPT TO JUMP START
THIS ENGINE.
If the battery should accidentally become discharged
disconnect the battery cables and recharge the battery
before attempting to start the unit. Boost/jump starting
this unit improperly will result in PERMANENT
DAMAGE TO THE ENGINE CONTROL MODULE
(ECM).
WARNING! EQUIPMENT DAMAGE
FAILURE TO PUT THE ENGINE CONTROL
SWITCH IN THE ‘OFF’ POSITION PRIOR TO CON-
NECTING THE BATTERY CABLE(S) MAY RESULT
IN DAMAGE TO THE ECM. (SOLID STATE ENGINE
CONTROL MODULE).
OPERATIONS
DESCRIPTION AND IDENTIFICA-
TION
A. FRONT PANEL
1. Starting Controls - This unit is equipped for
manual or automatic start. A three position switch
controls the engine starting.
a. “Off” - This switch position stops the engine and
disconnects the power from the engine control module. It
is intended to safely allow service and maintenance
checks on the engine
b. “RUN” - This switch position engages the start
circuitry in the engine control panel. The glow plugs
are turned on for 12 seconds and then the starter is
engaged. The engine control module in the control panel
will disengage the starter when the unit starts and
engage the engine monitoring sensors.
c. “AUTO” - This switch position is used when the
MD25 is used in a standby mode. With the switch in
this position a remote contact must be made to engage
the start circuitry. A terminal block has been provided
behind the customer connection door for you to wire your
remote contact to. This remote contact will be a dry
contact that will provide a ground on the start circuit to
engage the engine control module and start the unit .
2. DC control Circuit Breaker (DCCB) - The 15 amp
DC Circuit Breaker protects the engine controller and
wiring harness against faults in wiring or control
equipment. The DCCB also prevents a discharge of the
battery due to a circuit fault.
3. Glow Plug Indicator - This indicator light glows
red when the glow plug circuit is active.
4. Emergency Stop Switch - When depressed this
switch will disconnect all the 12 volt power to the engine
control panel shutting the engine down. The lamp in
the emergency stop switch will light up when the switch
is depressed showing that the power to the panel has
been disconnected.
5. Engine instruments
a. Oil pressure monitor gauge (OPG) - The oil pressure
gauge is mounted on the front control panel and indi-
cates the engine oil pressure. The gauge serves a dual
function. In addition to displaying the oil pressure it
also provides the shutdown signal to the engine control
module if the pressure should drop too low. The shut-
down signal is factory preset at 15 psi (103 kPa/m sq).
b. Coolant temperature monitor gauge (CTG) - The
