Hello,
My 2012karma ever 12volt battery died. After unsuccessful attempt to trickle charge it I replaced it with the same type of amg battery. Now I have no display, no infotainment center and no ability to put into drive, reverse, neutral and park does not light up. Car seems to initiate fine and lights come on but for all practical purposes it has become a beautiful paperweight . Hard reset of both HV and 12volt systems have been performed as well as no fuses are blown and none blew. Of course this is only in the fuse block under the hood. At a loss!!!!!
