What this circuit is supposed to do is: Turn on a DC motor with a button, turn it off with another, change its polarity with another BUT only when its turned off, and change thepolarity again (it doesn't have to be with just 4 buttons or just 2 relays but its the best i could figure out)
So i have 4 buttons, #1 starts the Relay1 which powers the motor and it rotates to the left, button #2 stops the relay and in turn the motor, button #3 turns on relay2 that makes the motor change its polarity so when you turn it on it rotates to the right but it doesn't turn it on, and it only can change to that direction when the motor is turned off, button #4 breaks the circuit that feeds relay2 so it changes the polarity of the motor again.
The problem i have is that button #4 breaks the circuit aka changes the polarity of the motor EVEN when the motor is on, which of course it should do only when its off and i just can't wrap my head on how to solve this, iwould appreciate if anyone could help me.
