TT battery

No it won't do any harm going down in size on your converter, but why would you want to do that?

I suppose it depends on how you camp and how many appliances and lights you plan to use. The converter converts 110 to 12 volts to power most of the stuff in your trailer. It there is anything left over it will charge the batteries. As long as you are plugged in, it shouldn't matter much. Your converter can always charge batteries at night.

I dry camp a lot and often use my generator for a few hours at a time. I have a 55 amp three stage converter. I can run lots of stuff in the trailer and still be able to charge the batteries. If I had a much smaller converter, it might take longer to keep the batteries up.

But no, it won't hurt if you move down in size. Are they that much cheaper?

I always camp where there is electrical hook ups. And the TT is always hook up to 110 when I work on it.

Generally no problem at all. Mostly you only need 10 to 20 amps. If the battery is super low it may take a little longer to charge up.

I replaced my 55a WFCO with a 35a WFCO. Works fine.

How many batteries do you have? If you have 2, or thinking of increasing the size of your battery bank or if you plan to do any camping without electrical hookups, I would not go to a smaller converter.

Manufacturers usually take advantage of any way to cut costs. They apparently felt that your TT needed the 40A converter. I vote for a 40A or 45A smart converter.

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?

You get 4.3 volts at one end of the wires and nothing at the other. Seems like the converter is bad but the wires don't seem to good either.

What do you mean "the wires don't seem to good either"?

I would expect the same voltage at both ends of the wires when they are not connected to anything.

Thanks I get what you meant. Just came in from the TT and yes I get both reading at the converter and the wires going to the battery. I must of not been holding the probes right. My next question is would it be bad from dropping from a 40 amp to a 30 amp converter, or should I stay at 40 amps?
