Well just when you think.....

Okay first of all I ordered my RV propane stuff and they came I was all excited to install it but they get the hose has the wrong connection so I have to order adapter so that's on hold and my slide out..
Okay so I got everything ready got everything out of the way it's all excited my brother sent me pictures of it working and I go and I go to turn the key for the slide out and the key just spins around it won't turn either way and then I hit enter out and there's absolutely nothing so am I missing something I don't know I guess I'll have to figure that out man I just thought everything was going so smooth and then of course this happens keeping my chin up though.
