Guys I have a problem, that is giving me and the customer (commercial cutter) fits. I am working on a Scag that is blowing the main 20 amp fuse, which also kills the engine. The mower will run from 20-45 minutes between blowing fuses. When it blows the fuse, you can jump of the seat, and replace the fuse and then go back to mowing until it blows the fuse again, then repeat the above and mow some more. Any ideas to what could be the problem.
