Does anyone know if the radio has it's own fuse on it somewhere?  I think I had crossed the wires when reconnecting my battery temporarily (doh!).  Never turned on the radio in that state or anything, but now everything is working except the radio, which was working before storage.  Owners manual suggests testing the fuse if it won't power up -all fuses in my main panel are fine, so I'm hoping it's a not too hard to find inline fuse somewhere, but before I take the whole thing apart looking for it, I thought I'd check the experience out there.

Oh - and since I'm here and lazy - has anyone marked up the fuses for the 176S (2018) and what each one is for?  I can figure it out, but our dealer just marked them as "15A" without labeling what they actually controlled - so if it's standard and someone's already got it - I'd take advantage of htat rather than having to pull every fuse and go test every 12V feature 🙂

Thanks!

most new radios/cd player are drawing power with the unit off. I hate to say this but I think reversed polarity will cook the radio. And as far as I have seen no internal fuses on audio equipment. There is a reverse polarity fuse in fuse panel but I think it turns off all 12dc circuits. Good luck  GBA!!SVA and they only way is to pull each fuse and write down what it runs.

We had the same situation when our battery was changed out. There is an automotive fuse directly on the back of the radio unit. Just remove the four mounting screws and the unit pulls straight out. There was alot of extra wire so it came out and you can turn it around easily. 
Once we replaced the fuse our unit worked fine. 
Good luck.

Thanks for quick responses!  In this case I'm going to hope that Dahlgrend is right over you Sunnyvalejoe 🙂    Any idea on fuse size?  Trying to avoid the back and forth trips to the storage lot and auto parts store, and even though I have read the manual (how unusual) it just says the generic "check fuse" but doesn't say anything about the size/type/location/etc.

my sony has a in line fuse on power wires. Not sure about Jensen. But I would think if battery was hooked up back wards the reverse polarity fuse on power convertyer would blow my is a 40 amp. Good luck just trying to help. GBAS!!SVJ

Please post a picture of what you find behind the radio.  I would like to just pull the fuse and permanently put that power eating, glowing monster to sleep!

So I finally got around to looking into this more detail.  Summary is that connecting the battery up backwards actually did trip 2 fuses - 40amp in the camper fuse/breaker box, and then also the 10amp on the back of the radio.  Luckily in the end both were easy and super cheap to replace.  only challenge was being careful when pulling the radio out of the wall doing it on my own not to drop it and yank out the wires 🙂   Hopefully pics come through.  But for radio, just basically pop off the 2 plastic covers on side of radio, remove the 4 screws, and carefully slide radio out.  there is an HDMI and audio cable on the left side (facing radio)  so be careful not to knock those off and drop them behind the wall on the way in or out, or if you disconnect them to work on them don't drop them in the hole (sorry I missed taking photo of that side).  There's a clip right above the fuse - easier to replace fuse and set radio down if you take the wire clip harness off first.  Then simple 10amp blade fuse pops out and back in.  

We haven't used the camper yet - counting down the days till our first trip, but I actually kinda like the radio while we were working in there.  Hopefully it's not too much of a power eating monster 🙂  Though display can be dimmed, and only a clock when powered off, might still look bright in the middle of the dark night!  

Thanks again - hopefully the post will help some other poor soul in the future 🙂

Great pictures and write up! It's nice to know what is behind my radio before I pull it out.  I plan to install a switch to cut all power to the radio for a couple of reasons: It draws power even when it's off, which kills the battery and the glowing light is just too bright for comfortable sleeping. Thanks for the post!
