    Check the voltage drop in the connections on the starter, the alternator and the battery. Yes, check them again.

    Check the voltage at the starter posts.

    If you never touched the connections, they may be dirty. Do itttt

    Both on and off, and also while cranking. The voltage shouldn't drop a lot. It sounds like a charging issue (bad connection or bad alt.) because the voltage is so low while driving.

    and run a dedicated ground on the alternator itself and replace all the other grounds on the engine.
    i bet its a ground issue.
