Grounded the cluster housing to the dash with a metal hanger bracket ensuring good cluster to non painted area of dash. Also did not take a reading with sender in tank. For this part of the test do I just put the red test lead on the top center post on the sender and black test lead on the ground flange? I figure I should have a little over a half a tank of gas. So this test should read a little over approx. 20 ohms?
