Turn on the engine and wait that the fan turn on and write again the news values.
Check with the following tables to see what is more like to your annotations.
Example 1:
If you annotation is like example 1 connect the yellow cable to cable 2
Example 2:
If you annotation is like example 2 connect the yellow cable to cable 2
Oil bulb connection
The device measure the voltage present in the original engine oil bulb, and share the same connection, you dont need remove or change anything. When the voltage in Orange cable is less to 5v the device understand that there is no oil pressure and will trigger the alarm and shutdown. To enable this alert the engine need get pressure in some moment.
Relay connection
You can optionally install a shutdown for the engine. There are many ways to stop a engine, the installator must be take care to choose the way that:
