KEEP ELECTRONIC CONTROL UNIT
CONNECTORS CLEAN
IMPORTANT:
Do not open control unit and do not
clean with a high-pressure spray. Moisture, dirt, and other
contaminants may cause permanent damage.
1. Keep terminals clean and free of foreign debris.
Moisture, dirt, and other contaminants may cause the
terminals to erode over time and not make a good
electrical connection.
2. If a connector is not in use, put on the proper dust cap
or an appropriate seal to protect it from foreign debris and
moisture.
3. Control units are not repairable.
4. Since control units are the components LEAST likely
to fail, isolate failure before replacing by completing a
diagnostic procedure. (See your Northern Lights
dealer.)
5. The wiring harness terminals and connectors for
electronic control units are repairable.
