Ok so issue 1 was fixed! Appreciate all your help everyone. When I put the new batteries back in, I accidentally put the generator cable on the negative
, after swaping, the generator is working now from outside AND control panel!
HOWEVER, now I have a new issue. Everything seems to work except the slide out... the switch on the control panel isn't doing anything (I have the RV engine off and emergency brake on). I've checked the controller below it was flashing 9 red lights (short somewhere) but after resetting it now its not flashing anything.
