Question about BMW Cars & Trucks
Basically how do you get 12vdc to the starter on an intermittent basis, meaning turning it over till it starts. Short answer: you can't. there's key recognition circuitry, let's say you bypass all that, ok: so then you have to deliver 12vdc at 500amps or so....that's a really thick wire and a heavy duty switch. Anything less than able to handle that WILL start a fire. It's done through a relay. I'm an electrical engineer, and could do it if I had to but really, all the crap necessary to do it right...just get it fixed.
