Bad signal Ch.2
The quality of the signal from the channel 2 transmitter
is poor.
• Disconnect the channel 2 wires from the back of the
indicator. Assuming channel 1 is working, move the
channel 1 wires from the channel 1 terminals to the
channel 1 terminals. If the error message remains,
then check the voltage at the power cable. If should
be between 11.5 and 16 volts.
• If the voltage is good, then make sure the power
lead is connected directly to the battery. Power from
any other source may be too “noisy”.
• If the error message still remains, then the indicator
may be defective.
• If the message is gone when the channel 1 wires are
substituted for channel 2, then the channel 2
transmitter is defective or the connector may not be
plugged in correctly.
LOW POWER - Input Power required 11VDC to 16VDC
The power voltage to the indicator from the battery is
less than 11 volts or greater than 16 volts.
• Make sure the power cable is adequately connected
at the terminal strip on the back of the indicator.
• Measure the voltage at the power cable at the back
of the indicator. It should be between 11 volts and
16 volts. If not, measure the voltage where the
power cable is connected to the battery. If the
voltage is greater than 16 volts, check the charging
system of the truck.
• Make sure the power cable connections at the
battery are clean and tight. The cable must be
connected directly to the batteries and not to an
accessory, ignition, or other connection in the dash.
