7.
If you find obstructions, debris, or dust, use compressed air to remove the obstruction, debris, or
dust from the fans and heat-exchanger area.
The heat-exchanger area can retain large amounts of dust or debris.
Multiple uses of compressed air is often necessary to clear this area.
Make sure to minimize fan rotation during compressed air use. You can
use a gloved hand to hold a fan in position, if necessary.
8.
If the rotation speed for both heat-exchanger fans is within the acceptable range and there is no
obvious obstruction, dust, or debris:
a.
Disconnect the connector (for choppers) or remove the coolant thermistor wires from the
connector. This makes it easier to measure only the resistance for the thermistors.
b.
Use a digital multimeter to measure the resistance from each thermistor wire, based on the
following codes and connector-pin locations:
c.
Look for a resistance value that is outside of the minimum or maximum in
:.
