I am unsure where to ask about this, I am looking to design a -12V circuit (or close to it, even -6V would work I guess). Unfortunately I know very little about circuit design. Chemistry I know boat loads, circuits soldering and simple stuff is about it. It needs to handle a decent number of amps. The reason is, I need to speed up the windshield wipers and I read a few places where instead of applying a ground, a -12V was appleid to the ground. Giving it a functional 24V drop. This resulted in a huge increase in speed of the wipers. Ideally, I will only turn it on using a switch, to be used in those extreme times of rain.
Edit: since it is going to a motor, extreme tightness of voltage is not needed, as right now the motor sees the typical in car fluctuations from the alternator.
Another option would be to convert 12V to 18V or so. I would try other wiper motors but I can't find any extra info and can't afford to just go willy nilly trying different ones out.
