There should be some kind of reset on the radio or the Sirius module...you just have to find it....of course you just cut power to the radio via the fuse and plug it back in..as for the generator..looks like it is a transfer switch issue..runs fine on AC...so one of the generator transfer poles on the transfer switch might be bad or loose (any electrician can do or you can open up switch and look at connections on bus)..in fact..mobile tech can do and they come to you...I have no idea of where in NC you are or I'd help you myself...
