Idk... The valve cover ground bolts jump around at first but end up .2 -.3 ohm at the radiator support. They read .5 ohm going to the alternator from valve cover bolts.

Back at the battery, If I put the probe to the neg terminal, and the other at the end of the 8 inch braided cable that goes to the chassis, It read 18.3 ohms. Normal?

The more I mess around with the harness, the more it makes that door chime noise(?) coming from under the dash in the cab. Any clue what thats about?
