Wiring Short only under shore power
The fuse that handles the dinette lights blows when I connect to AC power. It works fine when I am on solar or generator. Does that mean the short is between the fuse block and the 50 amp shore plug? ...

Does the fuse blow the minute you plug in to shore power? Does it matter if the light switch is on or off? Here's a couple things to think about or check.
Get some extra fuses ready.
On generator verify that the dinette light works. Turn off the dinette light and plug in shore power. Does the fuse blow?
While still plugged in to shore power turn on the dinette light. Does the fuse blow now?
Unplug shore power and turn off the dinette light.
If there is a bulb in the dinette light remove the bulb. If the light is an LED you'll probably have to take it down and possible cut one of the wires.
Plug in to shore power and see if the fuse blows.
If you have a multimeter take a voltage reading from both sides of the fuse to ground. Does the voltage jump to 120v when plugged in to shore power (it should not jump)
