Hi,I have a carrier supra 650. it is old one from other truck. after I install it. It has a error code, low batter. and I check the data on the screen. it shows "BATT 0V." I even replace the new batter. same result.
After turn on the machine, i can hear the "click" sound in the logic board box. and later alarm show on the control.
How can fix this issue?
I don;t know why "BATT 0V". which pin on the logic board get the power from batter?
see below link service manual for supra 650. page 86 show the electrical diagram.
any one know the answer? how to fix it?
