Hey everyone! This is my first post, I'm fairly new to RVing and recently have come against an issue that I can't resolve hoping I can get some help here.

PROBLEM:
My RV house power is dead and does not work. The generator does not start up from inside the control panel (its completely dead) and the generator does not start up from outside either button either (no power going to it).

I assumed my house batteries were toast (5 years old), so i purchased new ones put them in and the house lights turned on BUT the generator is still not getting power. Any ideas? Is there a reason why power would go to the house but no the control panel?

THING I'VE TRIED:
- I've checked all (i think) breakers and fuses.
- Plugging in shore power turns on the lights but not the control panel/generator
- Having the RV engine on does not seem to help either.
- The other componetns transfer box, converter, etc seem to work, but I'm not an expert either so not sure how to test it (wiling to learn).

Thanks in adavance!
David

Forgot to add my RV is a 2018 Thor ACE 30ft (A CLASS)

Is it possible you missed a cable for the batteries, one that goes to the generator? Letting us know that year/make/model you have of RV would help, along with the generator make would help.

Hey thanks for the response! I have a 2018 Thor ACE - Generator is Onan Cummins 5500. What do you mean by a wire to the generator? The power wire? Where can I locate that? Thanks

Do you have a multimeter? Go to the generator and take the front panel off. There should be a lug that the main power wire coming into the generator connects to. Check that for power. I'm not sure if your rig has a CB for the generator, but that's a start.

i also would use a meter to verify if 12 volt power is actually making its way to the generator. if you pull the front cover off the generator you should see where the 12 volt positive cable from the battery connects to the generator. it is in the front lower left area. check to see if you have 12 vdc from this connection to chassis ground. if you do the issue is within the generator. if you do not have power then the problem is between the generator and the battery.

there may be a 12 volt circuit breaker in the cable between the battery and the generator. if there is then it may need to be reset.

one other option would be to try to jump start the generator using a set of jumper cables. i have had to do this when our batteries were too low to start the generator. if the generator starts this way it point again to an issue with the cable between the generator and the batteries.

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.

Any thoughts?!

Ok fixed the issue. The problem was the wires fell out from the connections and were put in inproperly. So pushing another switch made the slide out extend

All is good now! Thanks everyone.
