Hi Jerry,
What makes you suspect a fuse? Total controller power failure, or some other kind of symptoms?
The controller has a full wiring schematic in the documentation. I'd begin by popping the lid off the controller and having a look inside for anything obviously burnt out and any fuses you might see inside, then work methodically from there.
I can't think of any reason Yaesu would put a fuse in the motor unit, so if it's genuinely a blown fuse, you won't have to dismantle your antennas to get to the bottom of it!

Well, it finally happened....After 14 years, my Yaesu G-5500 rotator blew a fuse......I think it is just the controller, but not sure yet.Any suggestions beside the obvious yaesu repair facility? I will be down until I get it fixed...... Jerry...KJ4EU _______________________________________________ Sent via AMSAT-BB@amsat.org.
