  Q: How do you test and diagnose conventional analog gauges in an instrument cluster on Nissan Quest?

  A: This procedure applies to conventional analog type gauges (NON-digital) only. The following tests relate to the conventional instrument cluster; if equipped with the electronic instrument cluster, testing should be conducted by a dealership service department or other qualified shop. All tests require the Ignition Switch to be turned to the Off position before testing. If the gauge pointer does not move from the empty or cold positions, check the Fuse. If the fuse is OK, locate the particular sending unit for the circuit being worked on and connect the sending unit connector to ground with a jumper wire. Turn the ignition key to On momentarily; if the pointer goes to the full or hot position, replace the sending unit. It is important to turn the key Off right away, as grounding the sending unit for too long could damage the gauge. If the pointer stays in the same position, use a jumper wire to ground the sending unit terminal on the back of the gauge. If necessary, consult the wiring diagrams at the end. If the pointer moves, the problem lies in the wiring between the gauge and the sending unit. If the pointer does not move with the sending unit terminal on the back of the gauge grounded, check for voltage at the other terminal of the gauge, which should not have voltage.
