Barracuda Rallye dash Temp and Oil gauges underreporting

Couple of simple things to check if you have the cluster out.

1. ground the metal gauge housing to a battery using a test lead. Then, hook another test lead to the positive side of the battery and touch it off the post of the gauge that goes to the round black connector. Do not leave it connected, just touch it to the post and the gauge needle should deflect to the right. Do this to both gauges to test them.

2. If cluster is installed, make sure its grounded . There should be a black ground wire running from the metal dash frame to the body on the passenger side just above the kick panel.

3. If all else fails , try another sending unit. The water temp is the easiest to try first.

4. Here's one that stumped me! If you had the clear lenses out, make sure they are installed properly. Mine were interfering with the sweep of the gauge needles and would not let the pointers advance to proper reading.
