The IQ system is a design that allows for the simplicity and ease of
operation. At start up the IQ system will calibrate for the ambient air
temperature and elevation to determine the air to fuel ratio setting for the
air band. There are no more calibrations needed after this point and the IQ
system will recalculate the airband adjustment as ambient temperature
❏ The screen is a 12 volt system and receives power from the transformer box next
to the IQ controller. Check power at the two terminal wires (blk & white) going
into the right side of the IQ control. Check all connections on the main PC board
and fuses.
❏ Check the Voltage regulator in the control box below Image (A). Make sure all
voltage is proper.
❏ Make sure the rocker switch on the heater outlet door is working (Picture below).
The switch is a two pole switch that closes once the door is opened. Power is
sent to the screen for illumination.
