Hi there,
I have BMV712. My B2 voltage reading was way off so I replaced the PCB on the shunt. The mistake I made was that I had a 702 PCB. I installed 702 PCB and instrument (712) display did not turn on. I replaced the 702 PCB with my original 712 PCB and the display head still didn't turn on.
Is it possible I damaged my instrument display by using 702 PCB with 712 display? Or is there something I can do to setup. I seem to remember when I installed the first time, the instrument lit up as soon as all connections were made.
Thanks!
Andy
