No power to Onan Quiet Diesel

Check for 12v at the switch...could just be a bad switch...also check the generator itself as I have seen remote disable switches on the generator...does the gene start at the generator with the switch there?...if so, then there could be a harness that goes to the switch near the generator loose...if not, then it could be more serious with gene itself and to ONAN it goes which I truly hope not...I would also call Jayco and check to see if support can tell you where there might be a fuse or better yet, exactly where the harness is that carries power to the generator.
