What to do if the Monosem CS 1200-12 Controller console won't switch on?

If the console does not switch on, there are several potential causes. First, check the fuse and replace it with a new 7.5 Amp fuse if it's burnt out. If it burns out again, inspect the wire harness for cuts or damage. Also, check for faulty battery connections by cleaning and retightening them. Examine the battery cables for damage and repair or replace them. Ensure the battery voltage is at least 10 volts; recharge or replace the battery if it's insufficient. Make sure that the wires are correctly connected to the battery. If none of these steps resolve the issue, it may be a faulty console.
