GustavoMy feet is hurting and my massaging gun broke. I tore it apart to find out what's going on: the motor smells a little bad but seems to be working when I power it directly, the 7.2V battery is outputting 6.8V but the charging circuit returns that the battery is depleted. I tried looking if there was something in the circuit that I could diagnostic with a multimeter, but nothing seemed useful.
Who I gonna call? @iFixit ?
