Thats perfect since the IMA rotor runs on 3 phase dc. The rest of the crap is 12 volts dc. Maybe your bro has experience with car stereos or rv wiring too?
Nah he is still learning, he only has a few more things of experience but, he is pretty good.
Belto, did you ever decide on a kill-switch design? After some reading, it seems FAS that cuts the injectors and keeps +12v on looks daunting to set up, but ignition-kill has some risks, given that you're sending unburnt fuel into the cat.
