Bad signal Ch.2
T h e q u a l i t y o f t h e s i g n a l f r o m t h e c h a n n e l 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
c h a n n e l 1 t e r m i n a l s t o t h e c h a n n e l 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.
