Generator EMS Open Ground

[Ksupaul]

Bought a Champion Inverter Generator and tested it out today with camper. My Progressive EMS is giving me an open ground error. Is the common or do I need to do something with the generator to prevent this error? I am electricity dumb. One thing to note, my dogbone 30-50 adapter did have a slight dark and melting look to one of the flat posts. Could this be the cause of the open ground? Obviously need a new one, but think maybe I am missing a step to the generator as well. Thanks all.

You need to make a grounding plug that goes in the generator when you have a EMS. Check out utube. Or you can buy one online. Change out the dog-bone and try to fine out why you have dark and melting spots. Hope this helps you. DDG

I made* a plug that bonds the generator neutral and it corrects the issue. It simply plugs into one of the 110v outlets and will prevent the EMS error.

*DISCLAIMER: unless you are qualified to make one correctly and safely, I would suggest just buying a pre-made one for $10.

You guys are great. Didn’t know quiet what to google to find answer but now I see it. Very easy fix. Surprised I didn’t know about this already. Guess not all my camping friends have EMS systems not that I think about it.

I just have been turning my ems off when using my generator.

I’ll need to look at these other options.

I have the same problem. I guess this will solve it:

yes that will work. My first experience was just like the OP when on my first trip and had to make one on the road. I never knew they even existed before.
