12 Volt Fading

I have a 2010 Dutchmen Colorado 5th wheel that appears to have a 12 volt electrical problem. When the 12 volt lights are turned on, they get progressively dimmer until they barely illuminate. I'm thinking it is either a bad power converter or the battery has a bad cell. Any thoughts on the cause and possible remedy?

Thank you.

I have the same problem with our 2009 Challenger. I've changed out the batteries; tightened all connections, traced all 12v wiring I can reach and still have the problem. I will say the power at the park we are at is very low - about 108-109v so that may be the problem or could be the converter is starting to go bad. I have testing equipment that will allow me to find the problem but, as usual, it is at home in Colorado and we are in Calif.

You have done a great job of describing a bad power converter.

If it's not putting out much current... Then exactly what you see will happen.

NOTE: that poor connections can cause this too depending on how the coach is wired.

Check the voltage out on the converter's terminal, and compare with he battery voltage.
Home is where I park it!

When on shore power, you should see at least 13.8 VDC at the batteries. If not, it is the converter. If the converter is faulty, now is a great time to upgrade to a better one that has a charge wizard built-in.

Sure sounds like a bad converter, a good digital volt meter is in order.

Thanks for the quick responses and all the great info! I am 99% sure it is the converter. I will check the voltage and the connections as suggested and go from there.

Again, thanks for all the help.
