DSE Control Module Won’t Turn On / Keeps Shutting Down

Three common issues can lead to a Control Module becoming inoperative. These are faulty wiring, incorrect supply voltage and high operating temperatures.

The first issue to check is temperature. You can quickly do temperature checks with a variety of tools. The temperature should not exceed around 70 degrees Celsius for most control modules. This issue can be remedied by simply leaving your Diesel generator inactive for a short period.

Next, make sure your Diesel generator battery is operational. The voltage supplied to your control module must also be in the correct range. The specifics depend on the model of DSE control module you’re using; it’s typically within the scope of 9-35V of DC power.

If these steps fail, it may be best to get a professional to examine any potential faulty wiring, fuses and batteries in your Genset.

Generator Won’t Respond to DSE Control Module Remote Start

Usually, you won’t remedy a generator fault that leads to your power solution becoming inoperable without experience. However, some easily fixed factors relating to your DSE control module may affect startup procedures. For example, wiring to glow plugs, solenoids and starter motors from the control module may lead to inoperative remote start procedures. Battery supply, polarity configuration and delay timers may also be an issue. Make sure to check all three on your control module to find a potential remedy!

What does the alarm on my DSE Control Module mean?
