No Coach Power

Need some HELP!
Itís been my custom, when winterizing my 2018 Forest River Sunseeker MBS Class C 2400W, to remove the coach 12 Volt Batteries and trickle charge them in my cellar for the winter.
I find I needed to do some changes inside and have put the two batteries back in. Did this by first turning the battery control switch to OFF, parallel reconnected the two fully charged batteries, and turned the control switch back on. This should have given the coach 12 volt power but no power was on in the coach. This always worked for me in my previous RV.
Not sure what to do now. Any suggestions would be appreciated.

Double check and make sure you connected the cables correctly at the coach. Like you said positive to positive and neg to neg.

If battery cables are connected properly per SeaDog suggestion, check all the 12v fuses in the converter located above the refrigerator.

There is a mini breaker that runs off the red power lead going into the fuse box. It could be close to the battery and has a red wire connected to it. The mini breaker has a tiny little button on the side of it. Push the mini button to reset the breaker.

I did as SeaDog suggested and the red and black cables are correctly connected. I do have a approx 2x3 box in the battery box that the Red (+) cable is connected to from the battery. I will look more closely for the reset button.
Thanks for all your suggestions. Iíll reply on my findings tomorrow.

No Coach Power

I did find the problem and now have 12 volt power to my coach.
The problem was as SeaDog pointed out earlier. I had a battery cable on the wrong battery terminal. I'm used to connecting BLACK cables to Negative and RED cables to Positive. My mistake was a hidden Red cable that was covered in a Black plastic cable cover and so I connected it to a Negative battery terminal. Once I looked closer under the cover I discovered the RED cable. Attached it to the Positive terminal to power was good.
I wonít make that mistake again. To make sure I donít up again I put red electrical tap on the cable end.
Thanks for all you help.
