TT battery

Does the model you have show a number or brand? How old is it?
Maybe the electric distribution panel has a model number?

Can you post what TT you have, they're all different as to the 12v distribution.
Just from the pictures, it looks like the PD 4600 kit has a separate socketed distribution board. I would assume that DC power would be distributed from that board.

35 or 45 amp version is fine.

Looking at this model and I'm confused. The one I have has wires going to fuse side. And this model I don't see where to install the wire to the fuses?

Ok the battery is at 12.5. With the battery disconnected I get nothing at the + & - wires. Took my multi meter and metered at the converter + & - poles while still hooked up to the shore power, and I get 4.3. So I guess the converter is bad? All I know that it's a 40 amp unit with glass fuses. Any suggestions on different models to replace it, with breaking the wallet?

With shore power connected, you should see 13.2-13.8 V. After the battery has rested for 24 hrs., you should measure 12.6v across the terminals. This is with no loads on the battery.

Had the shore power hooked up all day & night. Checked the battery and only got a reading of 12.6 still hooked up to the shore power. I really don't know the history of this battery.

This is a perfect application for the digital voltmeter from Harbor Freight (free or a couple of bucks depending on the promotion). It is small, and amazingly rugged. Plus, if it breaks or you lose it no big deal. I have a more expensive voltmeter at home, but have a Harbor Freight voltmeter in my trailer's storage compartment. Can be used for many situations, including this one.

I agree with all the above, especially testing with an actual volt meter at the battery. But you don't really need to disconnect any battery wires.

Set your meter on DC volts if it's not an auto ranging meter then set it to 20 V DC.

Put the red test probe on the battery positive (+ or POS) terminal.
Put the black test probe on the negative (- or NEG) terminal.

Read the voltage. This reading read be in the 12.xx volt range.

Now plug the trailer in and take a second reading. This reading should be in the 13 - 14.xx range if the battery is charging.

If the battery voltage is the same whether or not it's plugged in, then it's not charging.

While the RV is unplugged, connect a volt meter to the battery and note the voltage.
Now plug the RV in and note the voltage again. It should be 13.2VDC or more.
