Thor Four Winds Pioneer Stereo/Camera not working

Hey gang,
Thankful for this forum! We have a 2014 Four Winds 24ft C-class. I was charging our battery with an portable battery charger and somehow mixed the clamps up placing them on the wrong terminals. I quickly rectified this but now our Pioneer Stereo/camera display has stopped working altogether- no power. Checked the regular fuse box with no success and then read a few posts here about other fuses being located behind the stereo and under the hood. I have taken a pic of the fuse box under the hood and was hoping someone would know which fuse is for the stereo- our Thor manuel doesn't have that info and their are quite a few. Any help appreciated.

I dropped a wire to ground while wiring a thermometer/clock into our WS31. I had to pull every fuse in the box one-at-a-time to find the I blew. It turned out to be one of these large "J case" fuses. Since, when did you have to give up the price of a burger & fries to buy a fuse?! Sheesh

Did the same thing on my 2014 Four Winds. There is a fuse on the back side of the radio and is impossible to access without pulling the radio. Pulling the radio is a fun job. I gave up and took it to an automobile audio shop who in less than 15 minutes pulled the radio and replaced the fuse.

Hasn't happened for me in a long time, but I had several occurrences where the camera would stop working. I found that if I cycled power with the use/store switch that it would come back on line

Just something to try as a "hail Mary"
