MFJ-1924 Screwdriver Controller with Memory Instruction Manual
Installation (A)
Controllers that have six wires.
There are six wires that need to be connected in order for the controller to
function properly.
1. The red wire needs to be fused and connected to the vehicle’s +12
VDC supply. The size of the fuse depends upon the current requirement
of the antenna motor. Typically a 5 Amp slow-blow fuse will work.
Some installations may require additional wire. Use 16 AWG wire to
add additional length.
2. The black wire needs to be connected to the vehicle (station) ground.
If the supplied red and black wires are not long enough, Use 16 AWG
wire to add additional length.
WARNING: Do not reverse the polarity of the Red and Black
wires. Damage will occur to the controller.
3.
The remaining four wires are connected to the antenna. The Green and
Yellow wires are connected to the motor.
The polarity of the motor
connection determines the direction of the antenna. If the motor moves
in the wrong direction, swap the wires or see the menu setup section for
setting the correct direction.
4. The Brown and White wires are the sensor wires and should be
connected to the magnetic sensor on the antenna.
There is no polarity
associated with these wires. The following table shows the wire color
and connections.
Red +12VDC
Black Vehicle
Ground
Green Antenna Motor
Yellow Antenna Motor
Brown Magnetic Sensor
White Magnetic Sensor
You will need to connect wires to each of these four wires, so that they will
reach your screwdriver antenna. Use quality insulated wire for these extensions.
The motor control wires should be no smaller than 18 AWG. the sensor wires
should be no smaller than 24 AWG. Take care and follow your antenna
manufacturer’s suggestions about routing these wires for a mobile installation.
Avoid routing control wires with the feed line. Make sure a RF choke is placed
around the control lines at the antenna.
