Battery Charging

What size wire and what size converter? The wire size is printed on it and give us the brand and model of the converter.

PD4000 Series Power Control Center, this what you are looking for model of the converter?

As for the wire 8 gauge from the trailer into a wirenut(think that is what it's called?) then 10 gauge to the battery and another 10 gauge to the jack. The fuse is between the wirenut and the battery.

Ok, the white lead is negative, it runs to the frame of the TT while the green lead is the positive lead and has the inline fuse plus a lead running to the jack.
Now I did take the battery out for the winter, but I took a picture of the connection so when I put it back in I got the leads connected correctly.

Should be correct but the fuse is most likely the incorrect size.

If the converter output is 30 amps it cannot pass thru a 20 amp fuse.

Sounds a little small. Check the size of the wire from the battery to the 12 volt distribution panel. Check the size of the converter output. I would guess it should be at least a 30.
I think you have another issue. The truck isn't feeding much more then 20 at the connector.
I would check the polarity of your battery. It sounds like it could be reversed.

If understand what you are saying polarity is reversed is because I got the leads connected incorrectly? If I understand reversed polarity is positive post on the battery becomes the negative post and vice versa correct? If not please ignore below. My understanding of electrical is grab the wrong wire it a shocking experience.

Any thoughts or need more information please let me know.

YOu need a multi-meter to make some basic tests.

When it is not plugged in, do any of the 12 V accessories work ??

How do you charge the RV batteries?
