I don't know which bounder you have but mine has four 12v fuse boxes. One under the hood I believe by WH, one on top of the dash on the drivers side, one behind the same door for the 110 breaker box in the bedroom and one outside the entrance door with the slide open behind a removeable metal plate with more 12v fuses than any other place.

Bingo

Yes I found the 4th location under the hood above the radiator and it was fuse #22 that was blown, it was a large 20 amp fuse, after 5 years of ownership I never knew that fuse box was there.

Yes 4 locations of fuse boxes on my Bounder motorhome, why so many locations I will never understand.

First clip the wire on a good ground (IE Under the hook I often pick the brake lines) now touch the tip to a KNOWN good 12 volt (The big bolts/screws at the bottom of the BCC the one marked MAIN) bright light. GOOD

Now touch the metal tab inside the small window on the top of the fuse. both of them

LIGHT LIGHT Good
DARK DARK no test but in the specific it's not that fuse anyway
Light dark or Dark light DING DING DING you found it.

Yes most people don't realize that the fuses have little windows in the top of the fuse for testing. These windows are actually the top of the blades that plug into the fuse block. Just probe the positive of your meter or test light into the hole and your negative on a good ground and if it lights you have power.

A good fuse will light when you probe both windows.
A bad fuse will light on one window only.
If no light on either window there is no power to that fuse or your ground is no good.

A little off topic, but chasing down fuses is why I replaced all mine with lit fuses, so I can easily tell when they go.

In one of my vehicles its actually soldered to the back of the receptacle and is very tiny, easy to miss, impossible to see when installed in the dash.

Yep I think I will pick one up tomorrow and do a retest, checking fuses by eye did not pan out..

However there is about a hundred fuses located in 3 areas on this motorhome and so many listed as spares with fuses in them, nobody at the factory took the time to list where is goes..

Yea I think if its a burnt fuse than I don't see it, will have to test each fuse or get a new one and check each circuit, I wish it had the 12 volt fuse listed but mine does not, just a bunch of spares listed all over.

Well I am at my wits end, I have check every fuse in 3 loctations on the motorhome and no luck.

All fuses shows no signs of being burnt, next thing is to get a new fuse and check it this way in case I cant see the burnt fuse, nothing is mark for the 12 volt outlets, just spares listed thru out, wish I knew which one it was.

What have I done.
