Failure to follow instructions can lead to severe damage and personal injury.
TROUBLESHOOTINTG Q&A
Q: Why Doesn’t the Electric Fan turn on?
A: 1. Check all connections to make sure all wires are crimped correctly.
2. Check all Chassis Ground (-) connections to make sure all paint is sanded off and you are getting metal to metal contact.
Q: Why is the Electric Fan blowing in the wrong direction?
A: Switch the Positive (+) and Negative (-) Electric Fan leads. This will reverse the airflow direction.
Q: Why does my fan not come on at the desired temperature?
A: Make sure the thermostat switch is located as close to the inlet on the radiator as possible if the push in probe is used. This
will allow the switch to receive the most accurate and consistent reading.
