| Wrong sender used | For sender only applications ONLY a Dakota Digital |
| (for no gauge setup) | 300ºF sender can be used. Other senders may not give |

| Fan not connected properly | Remove fan output from unit and short wire to ground. If |
|
| fan does not run, check relay and fan connections. |
| Alternator overcharging | Use a voltmeter to measure the voltage at the battery |
| (Analog gauge applications only) | while the engine is running. If this voltage is above 15v |

| Fan off temp too low | Increase off temp in setup |
| Broken/shorted wire to sender | Check wire to sender for breaks or shorts and repair. |
| Wrong gauge is selected | Select appropriate gauge in setup, or custom calibrate if |
|
| your gauge is not supported. |
