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.

How are the batteries wired? If they are wired series the system is 48V and adding 2 batteries won't be easy (need a DC to DC converter with enough capacity to be useful). If they are wired parallel then just keep adding in parallel.
It is possible that the 4 batteries are wired as 2 pair of 2 in series for a 24V system. IN that case wire additional batteries in series then the PAIR in parallel with the 2 pair already in place.
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.
The Parallax 7155 converter should not require battery support for any 12 volt load amperage that is less than the maximum amperage capacity of the converter. A standard RV incandescent 12 volt lamp draws about 1.5 amperes for each bulb. With the battery disconnected and other 12 volt loads off, turn on lamps (not fixtures) and calculate the number of bulbs which can be turned on. If you run out of lamps, turn on vent fans etc. The idea here is to try to get to 55 amperes of DC load if possible without going over 55 amperes. At a sustained DC load of about 25-30 amperes or higher, the fans should cycle on continuously after about 5 -10 minutes. Lamp brightness should be normal and the measured voltage from the converter should be above 13 volts if under 55 amps of DC load. If the voltage drops with only a few lamps on, a converter issue would be likely.
Diagnostic tests an RV technician should make would be to:
1. Disconnect the battery system.
2. With the converter system powered on, measure the DC amperage with a DC ammeter capable of reading at least 60 amperes DC from the blue lead at the DC fuse panel terminal VCC.
3. Measure the DC voltage at terminal VCC and DC ground.
4. Record both readings.
At any DC load amperage less than 55 amps, the voltage should be above 13.0-13.2 volts DC. This method should take out all guesswork and confirm a DC converter section issue or not.
code p 0133 refers to heated oxygen sensor (HO2S) 1 bank 1---slow response ===causes ---heating inoperative --- wiring ---HO2S
also refers to oxygen sensor (O2S) 1 bank 1--slow response ===causes ---wiring ---O2S
also refers toHO2S 1 bank 1--no signal====causes wiring ---HO2S
the HO2S is the sensor in the exhaust manifold before the cat converter and reads the exhaust gas composition to report to the ECM to adjust air fuel mixture
For this code the HO2S needs replacing
the reference to an O2 S is the sensor after the cat converter and reports on the cat performance
code p0420 refers to catalytic converter bank 1-- efficiency below threshold ==== causes cat converter ---wiring ---HO2S
code p 0430 refers to the same as p 0420 but cat converter bank 2 causes the same including the HO2S
I would first get both HO2S sensors ( bank 1 and bank 2) replaced then have the fault codes read
if the cat converters are sill showing as the 420-430 codes then muffler shops have cheaper cats that what you were quoted
These replacements can be simple, but you will need to get a sensor socket or wrench in order to replace and some can be really rusted in the exhaust. The sensors are located ( depending on motor size v-6 or 4 cylinder) one on the exhaust manifold at the front of the motor and one on the catalytic converter. It will be a short stubby piece with 3-4 wires coming out of it.
