Power issue

[Amosmoses33]

You mentioned that all this started when you went to extend a bedroom slide. Is it possible a power cable got sliced causing it to short to ground? That would trip a main battery circuit breaker/fuse. In your case it sounds like an automatic resetting 12 volt circuit breaker is constantly trying to reset but is unable to do so because there is a massive current draw.

The circuit breaker that is auto resetting probably is a high current one meaning it is taking almost a dead short to prevent it from resetting plus all the sparking you are seeing is a good indication.

I don't believe your problem is in any of the fused 12 volt circuits as all of those fuses are lower values than the one that is tripping. If there was a problem in any branch circuit, its fuse would be the one blowing.

Odds are you have a main power line that is touching ground somewhere. You will probably have to see how the power is routed from the battery to the power distribution panel.

Anything is possible, but the slide didn't get out more than a half inch, if that, before everything cut off. It got dark on my so will do more tonight. I had to cut grass. Appreciate everyones help thus far, thank you!

You may be on to something. I looked under the slideout at lunch for a minute and could see a black wire trying to poke out the drive cylinder (my term). I'll have to manually crank it out and see what it is.

Solved

Solved....It was a worn wire at the slide. See pic.
Thank you all for the help. Glad it wasn't the converter or something big.

You definately are not getting 12 volt to or out of your fuse panel. Did you check the 12 volt disconnect switch
