Electrical Gremlin?

Here is a picture of the dash installed with the key off. I used the needles from the factory gauges that were no good any more and epoxied them to the needles they supplied for a "factory" look. Will post another with the engine running for comparison. Second picture is an exploded view of the gauge assembly, Equis™ are very easy and affordable to work on and they come apart fairly simply as well.
