Outerlimits1980 Posted July 23, 2022 Share Posted July 23, 2022 I just replaced all board on my power jack 8000 and am now getting low voltage shut down. Voltage just before alarm and shutdown is 14.5 DC and 87.4 for 110 and 175 for 220 My question is what possibly causing low voltage and is there possibly a way to fix this?

This is sounding almost like a 24v transformer being run on 12v DC? (If that's the case, you need a different transformer and/or need to rewind the one you have.)

dickson Posted July 23, 2022 Share Posted July 23, 2022 (edited) This is sounding almost like a 24v transformer being run on 12v DC? Maybe PJ or Ebay sent a wrong control board . The jumpers maybe set for 24 volt and not for a 12 volt control board ? Too difficult to rewind a toroid transformer and a different transformer will cost more than a new inverter .
