Brake and battery light come on on 2002 Mitsubishi Montero Sport

The battery and brake light came on at the same time. One week prior to this it wouldn't start, my husband tapped starter than it started. Had battery,starter and alt checked at AutoZone who stated all were good. PLEASE HELP!! What could this mean?

When both the battery and brake light are illuminated with the engine running it is usually a sign of an open circuit/no charging condition in the alternator itself. With the engine running watch the dash warning lights, get your husband to hit the alternator gently and see if the lights go out and the battery meter now reads charge. If so it is a connection in the alternator and the alternator should be replaced.
