Since we talked last I installed a 40" LCD with a swiveling and removable mounting plate, 6x9 3-way speakers and a remote JVC deck with custom mounting plate(fake leather). All thanks to help from this site.
Here is my new problem. I noticed my new deck would not work with the batteries off. When I engaged the battery via a battery switch, the deck worked. Then I disconnected the batteries via the switch and it still worked for a minute.
I have been in an rv park for 3 months now and living off of external AC power. Should I be connecting the batteries via the switch once in a while for charging, or is something else wrong?
I think it's going to take a lot more information to answer your question. If all the items are a/c units they would run off the park power while plugged in to the shore or from the inverter that would be connected to the coach batteries IF that is what you have. With the coach batteries disconnected they will lose some charge but shouldn't be much if they are in fact disconnected.
I think the key is no matter what the arrangement you need to charge the batteries every so often.
The deck is probably 12v and switches out when you open the disconnect.
If you want the deck to work close the disconnect. This will keep the batteries charged.
Not good to let the batteries discharge fully and leave them that way. Very short lifespan.

I have a battery disconnect switch in the trailer. I disconnect the batts when on external power. Should I connect the batts once in a while or should they charge regardless of switch position. Does this help?
If you look at the batteries, and see that the disconnect switch is the last thing to attach to them (no small wires), then the disconnect switch will keep them from charging. The power won't flow in either direction.
If there is a small wire also attached to the batteries, then you may have a charging connection, in which case they would charge any time you have power to the 110VAC, by way of the inverter/converter.
I don't quite know why the batteries would effect the television, unless you are not connected to 110VAC, or maybe there is a dead leg on a 50A service?? so those outlets are getting their power from the battery via the inverter?
I honestly don't think this is the case, as the transfer switch probably doesn't only switch half the connection.
I'm stumped too?

I have a 3-stage charger but still use my disconnect switch when connected to shore power for a week or longer at a time. My batteries seem to lose water if left on the converter. For long periods of disconnect, I will connect the switch for about 24 hours each month.
It may depend on the chemistry of the battery bank. Typically high antimonial content batteries such as golf carts loose 1% per day to self discharge. After a month they would be at about 75% of fully charged. Depending on the size of the bank (say 462 amp-hours?) that would mean over 115 amp-hours need to be replaced. at 13.2 volts that may take 168 hours. (one week)
If they are 12 volt marine batteries a similar size bank, when new, only self discharges about 1/2 that.
If they are AGM it is 1% per month--totally amazing!!!
