ELECTRICAL SYSTEM
VACUUM MOTOR
The vacuum motor is a very high speed motor that develops vacuum for the recovery sys-
tem. The motors are designed to give a service life of about 500 hours. See the “Recovery
System” chapter 5 for more information.
ACTUATORS
The MiniMAG uses only one actuator. This actuator is for lifting the brush deck. This is a
heavy duty 500 lb. actuator that has internal limit switches. See the “Brush Lift Section”
Chapter 8 for more information.
WIRING
The wiring on the machine is numbered for easy circuit determination and to be easy to
trace. We over size our wiring to eliminate failures and for safety reasons.
We use a number of different wire terminals on our machines and some require special
tools to properly service or replace them.
STANDARD CRIMP ON TERMINALS
The standard crimp on terminals we use on our equipment should be crimped with a posi-
tive stop ratchet type crimpers. The correct color coded terminal must be installed for the
machine to operate properly with it’s original integrity. It is important to use the Ratchet
style crimpers to assure the connector is installed properly. The ratchet style crimpers
regulates the crimp so it is not too tight or too loose. Using standard pliers style crimping
tools does not assure a consistent connection.
MOLEX CONNECTORS
Molex Mini Fit Jr. wire terminals are used where the wiring harness plugs into the control-
ler and the LCD display. These terminals require a special removal tool. If an attempt to
remove them is made without the removal tool it is very likely that the terminal and perhaps
the connector will be damaged and need to be replaced. To replace a Molex Mini Fit Jr.
terminal a special set of Molex brand crimpers is required to achieve an acceptable crimp.
