hey guys got a question i understand with the big 3 upgrade u do alt to battery and ground on battery to body and motor to body. now my question is for the motor to body ground is that just to make the ground on the alternator better. if thats the case can i just run a ground off the alt to the body instead of motor to body.
assuming that your alt is grounded to the engine through a conductive mounting bracket (i think most all of them are) then you could do alternator casing to chassis. the alternator mounting ports will work as the engine to car chassis ground.
