Please contact Mathers Controls for support information.
c) Check the voltage between the red and orange wires (pins 3 &
4). The reading should be 4.80 to 5.00 volts DC. Check the
voltage at pins 3 & 4 while depressing the transfer button. The
voltage reading should be less than 0.50 volts DC. Replace the
transfer button if the voltage remains at 5.00 volts.
17.2 SYMPTOM: O
INITIALLY TURNING
a) Port and Star-board power sources do not have a common
ground (only the starboard would be unable to take control)
b) Mis-wired eight (8) conductor cable.
c) Defective control head potentiometer.
d) One control head not in Neutral.
a) The negative terminals of both batteries must be connected to a
common point. If not, connect both to a common point.
b) The cable connections must be wired as shown in in Section 4.7,
Figure 6 and Figure 9.
c) Check the voltage between the yellow and the blue wires (pins 5
& 7) at the suspected control head. The reading should be 4.80
to 5.00 volts DC. Measure the voltage between the blue and
green wires for left hand control heads, and the yellow and
green wires for right hand control heads. The measurement
should be between 49% and 51% of that measured at pins 5
and 7 with the lever at the Neutral/Idle position. If not, replace
the control head or install a Control Head Repair Kit.
