I have some limited electronics experience...I wish to create a 1vAC current from a 12 vDC supply. The power requirement is small. it is to create a control current to fool my car computer into thinking that the engine is turning.
i guess that I need a square wave of 1/2 to 1 v peak. Normally this is generated by small metal bars passing magnet and creating a pulse to show that flywheel is turning. Just need enough to tell computer that something is happening. Thanks
