I am now finalizing a plan to change out the original inverter to a PD4045 unit. I see a couple of issues that need addressing. The original shore power end had the 30A plug cut off and the PO installed a normal house plug on the end. I will replace the cord with a new one and I can hopefully install it without have to remove the belly pan. My first question is that the 120V panel that is at the back of the trailer has a normal house white jacketed wire source cable. Does anyone know if there is a junction box that has the flexible shore power cable attached to the house wire? I am going to do a thorough search of the bathroom closet today and see if I can find one. I am going to assume that there is something as there is two different wires.
So my plan has become since the 120V power is at the back of the trailer and the 12V
is at the front, I am going to install the PD4045 at the front. I will take a 120V wire from the junction box to the PD which will then feed the original 120V panel. I will take a new shore power wire to the PD4045 to feed it. Now I have decided not to remove the inside panels to do an ultimate restoration. I want to use the camper now and enjoy it. One day in the future I will do all of that. So back to my thought, I will have two 120V wires attached to the structure and feed from the back to the front. No I was looking at the 12V
fuse panel trying to figure out what the wires are for. The purple wire was for everything that was back of the kitchen, lights, bathroom fan, and furnace fan. The yellow was for the all the lights in the front and the water pump. Now I could not figure out what the two blue wires were for. I am assuming that one of them is for the fridge but I am not sure if the fridge is a 3 way and if it is not then I have no idea. So if anyone has any comments on my proposal of how to change out the inverter/converter let me know. Any help on the 12V
panel would be great too. The manual is somewhat lacking in description of wire details.
Thanks for all your help!
