Dash Unit Never Reads Full

Connect tester (J-22344) to tank unit feed wire and observe dash unit. If gauge does not read full, check cluster fuse, dash unit and printed circuit connections, opens in printed circuits or shorts due to pinched wires in body harness. Remove dash unit and check. If dash unit reads okay, reconnect tank unit feed wire to tank unit and completely fill fuel tank. Note dash unit pointer with engine running. If pointer still does not go to full, disconnect feed wire to tank unit. Using an ohmmeter, check resistance of tank unit for 88-92 ohms with full tank. If resistance is low, check tank mounting area for damage.
