Battery charging problem on Solaris 1950

Something else came to mind last night. What powers the brakes? The tow vehicle or the house battery?
I am asking as it seems my house battery is not charging. The previous owner but a trickle charger on it but I though he did so because he did not keep the camper on shore power. I keep things in the fridge so I keep it plugged in. Went to turn the pump on yesterday after pulling out only to find the battery almost dead ( barely would get a light to glow) any idea why my house battery is not charging? For sure it should charge either off the TV or shore power? Sorry if this has been asked before. I did a search on the forum but could find an answer

The brakes are powered by tow vehicle through the brake controler. You other issue sounds like a converter problem or bad battery.

Ok thanks. As for the battery when it was plugged to the trickle charger it charged up. ( I guess I need to post this issues as a new thread)?

To test converter output. Plug into shore power test battery with VOM meter set to DC volts. You should get around 13.5 volts.

If your 7 pin on the TV is an add on it is very possible that the charge circuit is not installed or if it is factory it is possible the TV has a blown fuse for the charging circuit. There is also a 30 fuse in the trailer that covers the battery wiring for the charge circuit. I had issues with my controller intermittently giving me error codes and not having brakes on the camper it turns out that the controller was telling the truth. I jacked up the trailer and one brake only worked slightly one not at all and the other two worked fine. 4 new brake magnets and we were good to go! You can check the charge power at your TV 7 pin with the TV on check voltage between the lower left pin (7:00) and the upper right pin (1:00) it should read charging voltage. If it does move on to your camper battery if there is no charge voltage there (if the fuse is good) some thing wrong in the connections or the camper pig tail.

So what charges the house battery? The TV or the shore power? ( or both)
With my motorhome the battery only charged from shore power or the generator. But I have no clue with the TT

Is there any particular brand of deep cycle battery which you guys would recommend. Checked the battery and 5 of the cells were dry. Also the battery is charging at 12.9 volts. Is that sufficient?

I use Deka but any good brand name. Battery should be charging at 13.5 volts on shore power. I'd check again with good battery. Battery charges off both vehicle and shore

Yes, I created a new one for you. You have 2 problems, trailer brakes and battery charging.

All of the above should even the motor home should have. Check your TV 7 pin that is where the charge power comes from.

As Jim mentioned earlier, the converter will (or should) charge the battery when you are on shore power.

When towing the tow vehicle should charge the battery. As mainah mentioned, the fuse in the tow vehicle could be blown or missing.

Here is a picture of the 7 pin plug that plugs into the tow vehicle to show where you should see 12 volts (13.5 when running). My connector is only live when the engine is running.

Don't forget when you look at the connector on the TV it will be mirror image!
