my electrical system is modified but it seems to work good.car is a 77.i run a zxt internal regulated alternator.the output of the alternator goes on a short #10 wire directly to the bat terminal on the starter.the battery is in the back but i ran it on #2 welding cable and soldered lugs on.battery is a 925 amp odyssey dry cell i bought from john c.the ground side cable runs complete to the starter bolt on the engine.i have seen many problems with using car body for a high amperage ground.there is also a ground from the battery to the body and from the engine to the body.the megasquirt is mounted on the bulkhead behind passenger seat and the ms relay board is mounted behind the driver seat.the ms relay board is wired directly to the battery.all of my ms system run independantly of the old datsun wiring.do not buy alternators from kragens or discount places.a good alternator-starter shop is better.

ok here is something else, always ground as close as possible to gear being install. someone told me ground at the battery is best, not true, i did a powerful stero taht way and i cause serious voltage drop, i used 8 awg wire even. did the short wire ground no more probs. also, at least for natrual gruonding systems ie ground rods in earth, to much grounding can cause a ground loop, hence voultage on ground, do not know waht causes this, but i have seen it frist hand in our cable tv headends, just mounting the ms with a metal body with screws can cause a prety good ground. dont know if this helps, but you know more than i so i figure anything might be useful??
