Power issues

[jeffD]

I recently went camping in a site with full services. When I plugged in the 30 amp cord, I still had no 120 volts in the trailer. The green light was on the plug and the connection to the trailer, so I'm assuming there was power at the station. I have since checked the inverter and it does not work either. I have checked all breakers and fuses and everything looks right. There is a light flashing on the breaker box. I'm not sure if there is a way to reset the GFIs Everything to do with battery power in the trailer is fine. Any info would be appreciated

Did you check the breakers on the sub-panel? Usually behind the power center under the bench. Do you have EMS, if so is there a code? And finally, what breaker box has a flashing light? A photo would help with diagnosing the issue.

Thanks for the reply. I checked the panel under the seat this morning and one of the two breakers was tripped. I reset the breaker with no change. Not sure what EMS is.The flashing light is in the Main control panel under the seating area. It is for the lithium Operation Mode LED. Im not sure if it should be in the on or off position. I would Imaging the on Position. I can try to post a picture. I'm new to this site Thanks

If you have a removable power cord, remember you need to give it a turn when you connect it to the trailer to make a full connection.

I experienced the same thing, the EMS fried and power didn’t come through the other side of it. Take the top of it off and with shore power plugged in see if your tester reads power feeding in from the 30 amp cord and then if it makes it out of the EMS.
If that is the issue I wire nutted them together to bypass the EMS, and kept on traveling.
I’ve since then used an external monitor to plug into the pedestal.

Also Progressive gives a lifetime warranty and were very helpful.

Sometimes breakers will trip but they don't look tripped. You might try turning each breaker all the way off and then push them all the way back on.

GFCI outlets have their own reset/test buttons between the plug outlets, just like in your home kitchen. The exterior outlet on the passenger side is a GFCI outlet so check that. My trailer has a second one left side of the sink cabinet. They can go bad and not reset. If it doesn't reset, it will need replacement. A multi-meter can be used to test for power at the outlet.

EMS is an electrical management system that many people have installed. It's an ETI option. Doesn't sound like you have one.

If you have lithium batteries the charger should be switched to lithium. You may need to check the manual to see what the blinking means. You probably have a WFCO 8955 and the version that doesn't auto-detect.

If turning on the inverter doesn't feed 120 Volts to your outlets or the microwave doesn't come on you may have either a loose wire or a blown fuse. You'll need a multi-meter to test for those. Also check the battery connections are tight and not corroded.

Those are the best thoughts I've got for the moment.
