I have problems with unlatching relay with relay.. Schematics below:
The purpose for this is to light on car sidelights when car is unlocked, when pressing lock button it turn off sidelights. Car gives negative impulse for locking and/or unlocking.
My problem - When Door unlock impulse is given then 1st relay latch himself on so the lights are on (OK, thats what i need), but when i give lock impulse it do not energies 2nd relay to turn off sidelights.
What im doing wrong?
