Started the car and drove about a block and the siren came on and off. Started to see a faint grayish smoke on the battery side. Couldn't find the source. A continuous clicking noise persisted for about 2 minutes on the driver side under the hood. More like under the wiper/ fire wall area. The car was fine when I parked it for approx 3 months. The only thing I did was put trickle charge on it and disconnected the battery
