Rob;
        Not sure how you are taking that reading. The resistance from
chassis to engine should be zero. Be aware this could be deceiving if
there is any parasitic current flowing. A better check is to start the
engine and check the voltage between the chassis and engine, with and
without all electrical consumers on. Ideally it should be as close to
zero as possible. Repeat this check between the alternator case and the
negative battery post. While you are there check losses between the
alternator output and positive battery terminal. Again, all should be
less than .25 volts. I have achieved less than .1 volts.

Good Luck and Drive Safely
