Clark Posted June 4, 2021 Share Posted June 4, 2021 The light on my PJ's Driver Board is not lit and both phases are now "slow" to start up. Recently, when I start my dryer connected to L1, it's starts up fine. On L2, the dryer struggles to start for one or just shy of 1 second. Now that is happening on both phases. I'm seeing "energy" issues on my other appliances as well. So, I ordered a replacement 7.0 Whole control board (including the charger board) from PowerJackInverter.com. $85, not bad. I just got an email telling me they do not stock the 7.0. They offered to send me the new 11.0 board. I would need a new LCD for $30. They also asked me for a Photo of the AC side of the inverter. I don't have the one or two micro rotary switches like the new ones. I have the one micro Rotary knob for the charging selection. Note: email is coming from youlung.com. I have been to that site years ago ( still in my browser history ) but the site is not active now. So now the questions. Anyone ever upgrade their electronics from 7.0 to 9/10 or ?? Has anyone heard of an 11.0 board? Should I try it or look elsewhere ? Ed. Quote Link to comment Share on other sites More sharing options...
