Perplexed!
We made good progress today by getting the dash with the factory gauges & tach reinstalled and all the connections made to the proper homes. Before we got too far we connected the battery to see if there was any smoke or fire or blown fuses...none thank goodness. Then (with the key in the off position) we turned on the headlights, then the emergency flashers and noticed the oil & water gauges were pulsating with the flasher rhythm...weird. They didn't do it when the key was in the 'run' position...hmmm. Checked the fuses again and none were blown...good. Checked all the other electronics to make sure they were getting power, which they were, except for the wipers...what the heck! So we decided to see if the car would crank and start...it did...yeah! The tach worked, the fuel & volt gauges worked, but the oil & water temp gauges weren't...crap! Oil would read at a little below '0' zero and stayed there when the engine was running and rest a little above when off. The water temp would read a little below '0' zero when running (even when fully warmed up) then rest slightly above the 1/4 (155 degree?) hash mark when off. We're wondering if the printed circuit may have bad grounds and pathway circuits as it is the original. We checked all the grounds that are associated with the dash harness and they were solid and tight. The pictures are of the gauges when key is 'off'. So we have some more work ahead for us now...once we can figure out what the heck is wrong.
Anyone have any insight on what the issue(s) may be? Printed circuit?
