Can any of you guys provide a diagram of how to test the ground with a DMM? I dont really understand where you put the meters probes and the wire form the battery negative confusing me? Or a link to show me how to do it .

test between the wire you grounded and another bare metal ground spot. the best is to run a jumper wire to the neg side of the battery. the meter should read 0 ohm's.

Nothing is impossable, it's just more expensive.

yup, but it should probably read like .01 ohms or what ever, , not 0 because its nearly impossible. as long as its not near or over 1 ohm
