Reconnect Battery and Lights Donít Work

Hereís a little stumper on my 2012 Keystone Cougar 24RLS TT:

I recently disconnected my battery And recharged it successfully at home. Bought a second battery to add. But I just reconnected my original battery at the trailer to make sure all is well... itís not!

Lights will not turn on inside. Iíve thrown the battery disconnect switch to Ēon.Ē Ceiling light switch is on inside. Battery cables are tight. Canít figure out what in the world is wrong!! The power hitch does work, however. There is a circuit breaker reset switch near batteries (which Iíve pressed a few times). No help.

Posting photos In the hopes someone can suggest whatís wrong. Are my cables connected properly? Help is appreciated.

Might want to check the 40 amp fuses at the power distribution panel. They can blow if the polarity is reversed even if for only a second

Didn't see a pic. Could be you jumpered them wrong since you added a battery or momentarily connected the backwards or.... The pic will help.
