Hi, I am not familiar with your 1997 coach AC power system at all. You said you have AC power working into the “fuse box” OK, but no AC out of the “breaker box”...... are these actually two different power boxes in your coach or are they the same thing? Probably separate.
The breakers are good, but if the power buses they plug or bolt onto have no AC power feeding them then nothing comes through. So what is between the “fuse box” and “breaker box”......transfer switch perhaps? Not sure but it sounds like your cheater cord bypassed whatever is supposed to connect the “fuse box” to the “breaker box”.
What happens when you start your generator? Usually 30 seconds after the gen starts you should hear the transfer switch operate.......try to determine where that sound is coming from to find the transfer switch and check it out. If your cheater cord was connected to the shore feeder (“fused strip” you called it) side of the transfer switch then you bypassed the transfer switch.
