I have voltronic inverter 3k fan stops with code 01 its mean fan need a replacement
old fan in pic pic-01 soits use us62 ic so i order new fan pic-02 and its not working first reason the cables reversed gnd and signal and pulse are normally measured by connecting the signal and gnd on old fan but on the new one it's not it can measure only by conneст signal and vcc also signal is reversed its use LB11967V driver on RD pin

my question how can to reverse the signal and measure it with signal and gnd
