The answer to 'my generator installation won't turn on' is that there could be several common causes, such as a dead battery, loose connections, or a problem with the generator itself. First, check the battery to ensure it is charged and properly connected. Next, inspect the wiring and connections to make sure they are secure and not damaged. If those checks don't reveal the issue, there may be a problem with the generator that will require professional diagnosis and repair.
If you've checked the basics and the generator still won't start, it's best to call in a licensed and experienced electrician to diagnose and fix the problem. Attempting to repair a generator without the proper knowledge and tools can be dangerous and may end up causing more damage.
