Electrical
The amplifier connects into the system via a four way Mini Sure
Seal (MSS) socket, the larger of the two connectors on the
amplifier. Use the extender cable supplied to connect the
amplifier to the WS input on the harness.
Use the vehicle speed extension harness with a MSS connector at
one end and two wires at the other to connect the amplifier to the
speed sensor.
For a two wire sensor, connect sensor wires to the white and
black wires on the cable.
For a three wire sensor, such as 5291 & 5292, connect black wire
to common ground with sensor and connect the white wire to the
sensor signal.
Adjustment
Once the system has been fully wired power should be applied.
At this stage it is desirable to arrange for the sensor to generate a
low frequency signal by spinning the wheel slowly. The red LED
at the end of the amplifier should be seen to flash as each signal
is received. If the frequency is higher than approximately 10
flashes/second the LED may only appear to dim, as the flashing
is too fast for the eye to see.
If this does not happen (the LED is always on or off) it will be
necessary to adjust the input sensitivity of the amplifier to match
the sensor. This is accomplished by turning the small screw
head, which is recessed, in the hole adjacent to the LED. This
should be adjusted until the LED flashes consistently.
The operation should be checked at the lowest possible
frequency, as this is the most likely speed for problems to occur.
Following these adjustments, correct operation can be verified by
observing the LCD speedometer at a range of speeds.
