Model 2011 jay flight g2 when hooked to AC power has 120 volts on external TV connector. Can I get an electrical schematic for the 29RLS floor plan?

What you are saying is when you connect that motor home to a shoreline power connector, the outlets are reverse polarity. You can confirm that with something like this:
You can get this tester at any hardware or lumber place. What caused this? Somehow the polarity got reversed and it is most likely at the connection on the outside socket. It can also be the shoreline drop cord or the breaker box. In an electrical outlet, the small slot is HOT and it should be connected to a BLACK wire. In an appliance like a television the neutral wire (white) is connected to the ground or the chassis of the device, when the polarity is wrong the chassis becomes hot and you get the problem you describe.

Capacator in lower left corner is blown apart from an 220v generator connection.... where can i get a replacement capacator or board ?

The capacitors are industry standard items that can be cross referenced from the component markings, values, or part numbers referenced on the components through several national component suppliers such as Digikey, Mouser Electronics, or Newark Electronics. If a single bulk capacitor has blown, both should be replaced as the other will have been stressed and should not be trusted to be functionally sound.

Wiring parallax 7300 series converter

If the white wire is the large # 10 AWG on the DC output, connect it to terminal "D" on the backside of the DC fuse panel. The front side of terminal "D" carries the 12 volt system negative or battery negative wiring. Refer to the wiring label pasted to the inside surface of the drop open door for terminal locations.

If the white wire is the smaller #12 AWG, 120VAC "common" or neutral, connect it to the isolated neutral terminal bar in the 120VAC circuit breaker compartment where the other white 120VAC neutral wiring is connected. The 120VAC isolated neutral terminal bar will have a full length plastic insulator under it and will not be directly connected to the chassis.

Check to see if you have power going into the switch. This can be done with a voltage meter at the terminals were the cable runs into the transfer switch. Do you have power at the generator plug?

Sounds like the electritian wired something wrong. Control wiring for that generator should be:
N1 and N2 = 240 vac utility input
Wire 0 = ground
Wire 194 (15B) = + battery
wire 23 = transfer signal
