Backwards buttons

[rmnpcolorado]

Here’s a weird deal that I’ve never run across before. We brought our trailer home for the summer and are ready to go out on our first weekend voyage and the button actions are backwards. Slide in sends the slide out, retract extends the tongue jacks. We’ve fried two 40amp fuses, which leads me to believe that something’s crossed, so we have no fridge power or lights. Thoughts?

Can’t think of any possible reason to have a fused wire on the negative post.
Typically there is one large wire on the negative post going to your metal frame for all grounding. The positive post will typically have one large wire connected and possibly a couple or more smaller wires often with in-line fuses connected directly or indirectly to that positive post.

So to clarify, I had the large wires correct-white on positive, black on negative. But what about the little wires? I had the white on positive and the red with the inline fuse on negative.

could be a senior momment, we all have them .lucky you didn,t fry a lot of things.

I think you’re exactly right, as when I disconnected the battery, replaced the fuses, and powered back up, all was good.

Now to figure out how I messed that up. I’ve only done this how many times before…

I agree. The battery is wired backward.

You got the battery hooked up correctly?
