Well I installed or should I say hard wired my surge protector in and when I hooked up my generator through the shore side it came up with a E-2 error. Meaning a Open Ground. So I shut down the generator double checked my wiring and everything was good. So I started looking to see what a open ground was. And I guess it's a ground wire that is not hooked up on the 110 side. Some where! So I went through and checked everything and could not find anything. Only thing I didn't check was the ac units. Now everything worked before and now that it shows a error it wont let power past the surge protector. I'm afraid to by pass or eliminate the surge protector to see if it (surge protector) is the problem but I not sure everything is ok now because of the error. I know everything was working with the generator setup before. So I guess it's a call to Progressive tech line to see what they think could be wrong. Anyone else run into this when installing one?
