2005 Kountry Star 3909, no power to the front ac, plug ins front part of the coach not working. , I've triple checked the breakers and fuses, any ideas ?

Get out your voltmeter.

Check to see whether you still have both power legs at the shorepower post, and if there also inside to your breaker box.

Sounds like you dropped one of the legs at the shorepower, or your cord has a problem, or your transfer box isn't passing both legs.

I can run the generator and makes no difference

Did you try resetting your GFCI outlets? There should be one in the bathroom and one in kitchen area. They each affect various outlets I believe.

Let us know what you find.
Best of luck,

Cheers

Yes , but no luck

Could be a couple things.

1) check your transfer switch on the load side to make sure you're getting both legs from the line side (either generator or shore power).

2) It could be a bad inverter/converter/charger. They too have a transfer switch in them, and sometimes one side will go bad. Check input on both legs and then output on both legs. If both inputs are good on both legs, but only 1 leg output, you have your culprit.

A voltmeter is your best friend.

The transfer switch (I believe) has a male plugin , the female receptacle that it plugs into has no power at it , I know the inverter must be working, the light are on

I do not understand your response. According to your first quote, it seems you have a 50A diesel pusher (?). If so, there are no plug-ins to your transfer switch at the shore power / generator unless someone modified the coach along the way.

Just because your lights are on on the inverter, doesn't mean it's working.

Please note, most high-end coaches have a combination converter/charger and possibly an inverter built in to one unit (as in my coach). It is possible that one side of this system is ka-put, which will limit shore power to half of the breakers in your coach. Thus the symptoms you describe.

Again, you need a volt meter to chase this down. Start from the shore power side, check the transfer switch, and then on to the coverter/charger. The inverter is incidential in this conversation. They do not power air conditioners.
