Hello all, I recently acquired a 2018 Grand Design/Imagine 2670mk. First one. We love it, but I have an electrical issue that I cannot solve. This is a generator/inverter question.
I have a brand new Onan (Cummins) P4500i inverter. Very nice and pretty quiet.
I can plug in the 50 amp shore power line to the 30 amp adapter to a 110 extension cord (I use a heavy duty 10 gauge extension cord). When plugged in to a 110 wall socket at home, no problem. Wonderful (except I'm only a 15 or 20 amp circuit, max...I am limited without a single 30 amp circuit / breaker at home.). So no A/C. But generally operates everything else, including recharging the batteries.
However, when I try to connect either the 30 amp adapter, or the 110 extension cord to the inverter, and connect either to the 50 amp shore power line to the camper...I get nothing. The generator is showing 124v, and on the power draw output...nada, zip, zed, zero, goose eggs.
In a twist, when I plug that same extension cord directly into the running generator, and then directly into an appliance, say a coffee maker or TV, I show a nominal wattage draw, and the appliance works perfectly.
I have checked all the breakers inside the 2670. I have also checked all the breakers and reset buttons on the generator. I took the generator to the local Cummins dealer/service center and they checked the voltage output on both 110 and 30 amp plug...both match the 124v output showing on the readout. So the inverter appears to be working perfectly.
When I then unplug the inverter, and immediately go back to plug in to 110, everything kicks back on.
I am perplexed, flummoxed, confused. The dealer I bought it from is 120 miles away (bad decision, especially when I have four RV dealers here). I just stopped at a local RV dealer, and asked questions..they tried to be helpful, but they too are flummoxed. The sales guy mentioned a "kill switch" that may switch from battery to shore power, but the only switch I can find is the battery disconnect switch in the front pass-through area.
I am thinking that this must be something simple and overlooked. Help.
