[QUOTE="keep_hope_alive, post: 7751273, member: 576029"] what DMM are you using? some are inaccurate at low resistances. i insert a 10 ohm resistor in series to allow for more accuracy. and good point about having the car on. i disconnect the battery before performing the ground resistance test. you may have resistance through the paint where you are testing. just touching metal is touching paint. that is why we remove paint to make a ground.
