No Power from Shore Power and will not charge batteries

[jerichorick]

Airstream14 did you use a meter to check your batteries or did you just go by the indications? Your problem is greater. What condition are the individual cells in? Are they all watered correctly? If you were to have a dead battery, even a defective cell, it would cause the entire string to suffer.

What brand of inverter do you have? Did you check the charging conditions in the manual? A string of batteries that are "dead" will draw high current for several hours as previously stated by another poster.

Many coaches use a charging solenoid. It is part of the AUX battery switch system. These are known to fail. This could be what is happening in your case. As a couple of us have already stated, you need to investigate your charging system in more depth.

I ended up buying 2 batteries that start the coach. This fixed the problem I guess because it takes some voltage to get a contact to close and allow charging. Also I turned off the converter when I disconnected from shore power. I think there was some current draw through it when parked. It did not run down for 2 weeks and starts right up now. Hope that does it

Thanks everyone for your help !

I had a similar situation. When plugged into shore power, my AC would work and the house batteries would charge most of the time, but randomly, the AC would go off and nothing would work. I started by going through all of the wiring to the transfer switch (ATS). I discovered that the white wire going to the ATS was loose. It was not only loose, but about 6 inches of the wire insulation was burned. My transfer switch was an old mechanical model, so I replace it with a digital switch and installed all new wiring. Everything works great now (knock on wood!).

When going from shore power to generator, the older models wouldn't always switch automatically. You could burn them up if you were on shore power and started the generator. The newer models switch over automatically whenever you start the generator.

Thanks all for your input. Even tho It is working now I am going to take your advice and check all cable connections and clean or replace as needed to prevent future problems.

Hi, If you still have you battery charger plugged in your inverter / charger is reading the voltage from your charger not your batteries . that's probably why its going into float . Try unplugging your charger and see if that helps.

I am going to go through all the wiring and check for bad connections just in case. It may stop a future problem.
Thanks all for your help.
