The gennie itself runs good. It's the electrical power output that's bad. The other day I started it up and ran it for about 5 minutes and then after seeing it was putting out over 120 watts at the 50 amp input, I started up the convection oven and inside of 30 seconds, the power on the gauge dropped to under 100 watts and the oven shutoff. I then put a cup of water in a glass and started the micro and that lasted enuff time to let out a groan and drpped off.Sooo, i lowered the temp on the ACs and fired them up, nothing. Dropped the front AC off line and the rear one came on. Reversed them and the front wouldn't come on. turned it off and let the gennie run for a bit and shut it down. Plugged the shorepower back in and set the input to 20 amps and the front AC came on. ??? shut it off and started the rear one on and it ran ????
