BTW, in the picture above, does anybody understand the term "REVERSE BATTERY FUSES?" What are they, where are they located? I have not had time to research this and have not previously read this terminology in other RV manuals.

I'll give it a shot even though I'm certainly not in the league of you electrician types.

This/these fuses will "blow" if you reverse the positive/negative cables by mistake.  Many years ago I did this and even though I replaced the blown fuse in the old RV, I neglected to even think that there just might be one of these in my Tacoma too.  Fast forward a couple of weeks and I'm scrambling to figure out why the Taco is not charging the RV batteries.  Fast forward another three days and I came upon another blown fuse in the Taco.  Strange - now everything works as it should!

@Ronbrink   Any display that is on may be running on 12v, such as the smart shunt's Bluetooth radio you are communicating with while viewing the Victron Connect app.  The propane/CO Detector is always on for safety reasons.  The only way that comes to mind is a DC clamp on meter and start testing circuits.

I don’t know about that, but my Oliver has a ‘reverse polarity fuse’ under the street side bed next to the 60A breaker for the DC buss bar. I purposely have the breaker tripped in this pic, the red rubber boot next to the breaker is said fuse.

That said, in theory if you turn off/ flip the main breaker or master switch, you should be killing all battery power. 

In theory, if you turn off the main manual reset breaker powering the inverter/charger and similar breaker powering the DC buss, you will be killing all battery power. 

 

Mystery solved! By manually tripping the 200A breaker shown in the upper right-hand corner and the 60A breaker in the lower left-hand corner of the below pic, the battery bank is totally isolated; thus no 12V power draw from the batteries by the Oliver, as evidenced by the above VictronConnect screenshot.

OK, I'll buy that you are killing the battery bay bank. 

But then, have you not seen your tail lights very faintly when you think EVERYTHING is off?  Just saying lots of opportunities that could come into play.  

Glad you figured it out.  

What does the reverse power fuse/breaker do for us?  Thanks

jd1923 cited some reading material in an earlier post:  Should Inverter Be On When Plugged Into Shore Power? Ultimate Answer (rvgoer.com). In reading, I was directed to other articles by this author and came upon the following:

Huh!  I always thought that was an automatically resetting breaker.
