What to do if Monosem Controller does not switch on?
- MMichael MorrisAug 10, 2025
If the Monosem Controller console doesn't switch on and the diodes don't light up, several issues could be the cause. First, check that the supply harness is correctly connected to the tractor’s 3-pin outlet or the battery, ensuring the lugs are clean and crimped properly. Next, verify that the battery voltage is between 10 and 15 Volts. Also, inspect the fuse on the console’s supply harness and replace it with a 5 AMPERE fuse if necessary. If the fuse blows again, it is recommended to contact after-sales service.
