Hi Ron ,KISS .......
thanks for all the encouragement and your persistence.Finally i made the breakthrough and successfully reversed the motor with the same relay.
Ron ,Your first circuit was 90% correct ;i made a little modification to it:The power supply to the relay coil and the NC and NO contacts must not be tied together or in series.I wish i could provide you with the revised drawing but save browsing the net i m an ignoramus when it come to computers .
Ron ,the first and second circuits you posted is precisely not the relay i am using.I am actually using Omron standard 3PDT Omron MK3P-I relay with mechanical indicator.
Pin 1 is the common for Pin 5 (NC) and Pin 4 (NO) whiles pin 3 is the common for pin 7(NC) and pin 6(NO).Pins 2 and 10 are meant for the relay coils. Wire the two common wires from pins 3 and 1 to the motor.Now two wires(12V DC) must be connected to two NC contacts eg Pin 5&7 and the motor will begin to turn clockwise in direction as long as the relay coil is de-energized.
Next,another wire must be wired from Pin 7(NC) to pin 4(NO) and wire a new from pin 5(NC) to pin 6 (NO);then simply energize the relay coil and the motor begin to turn counterclockwise and vice versa.
