Rpod 191 Slide out Failure

Maybe so, I think the issue was that it was winter & very cold the day I installed the new battery at the storage facility, about 0 degrees and i was in a hurry!

Mistakes happen. Now you know. Install a battery cut-off switch and then you won't have to worry about reversed leads. That is, until you need to change a battery.

There is always some current flowing to that circuit through the LED, which is why the LED can light. It just is a very low current, insufficient to do more than light the LED to let you know the fuse is blown. When you put the fuse in, there will be a little spark, not a big arc (that makes it sound like a welder) and the LED will go out since there is a lower resistance path for the current to travel. Just to be sure, I went out and pulled the fuse for my slide-out, and the LED lit. When I put the fuse back in, there was a little spark until I got the blades in place to push in and seat it properly.

Thanks for your reply. I will disconnect battery, install new fuse & attach battery & see if it blows immediately or when I attempt to operate the slide out switch. The arcing was a concern since this is for the slide out, and since I wasnt operating it at the time of fuse install, there shouldn't have been any current draw. So, I was concerned about the arcing.
