Just wondering if the OP has successfully fixed his charger/convertor problem?

So unfortunately not. I haven't had time lately due to having our first kid, the motorhome has been put on the back burner for a minute. I'm working on getting a new battery for it. So when I took the old battery out, I decided to hook up shore power and see if I got 12 volts on any of the posts I was taking reads off of before. Because I figured if it was converting correctly that I should be able to see at those posts if it is or not. Is that a stupid test? It made sense in my head but don't know if it makes sense or not. But the results were 8 volts on one side and then shore power on the other side. Does that show anything or not? I was working on pulling out the converter since I'm pretty sure thats my issue but haven't gotten around to finishing it since I'm a lot more busy with other things now. Thats what my gut tells me the issue is but this thing has me thinking all sorts of different things so who knows!

I got the converter part out. Where do I go from here? When I got the battery charge board from Progressive, they also sent me some of the black tube looking things because they occasionally go out also, do I try and replace that?

Be more descriptive, what do you mean by “black tune looking things”? Can’t tell by looking at your photo.

Its the black tube thing at the bottom of the picture. Its hooked to the silver thing in the corner and hooks to the thing on the right side of the picture. Its almost made of like ceramic. The guy told me its a "Ceramic resistor".

It is a resistor. Resistors get larger with higher watt ratings to dissipate the heat.

Either way just replace that converter already.

For a couple of hundred $ you would be getting a multi stage converter .

My opinion at this point is that the SCR component in this converter has most likely failed due to an earlier reversed polarity house battery hookup. That black ceramic high temperature resistor may also have been damaged. But since the owner is apparently not familiar with basic electronic component terms, his ability to repair this converter is in doubt. The best solution may be just to have the whole system replaced with a new unit by a qualified RV repair shop.
