I think my battery charger quick working. The DC power side is fine, but when I try to charge my Sony or Switronix battery, I only get a flashing a yellow light. The gas gauge doesn't seem to work at all... Anyone have this problem?
I don't know which model of charger I have, but on mine a flashing light means its charging. The faster it flashes the more its charged, until the light stays on full time, at which time its done. (I have difficulty telling a yellow from green light.)
