Re: Temp Gage Reads Too High
Thanks for the replies so far. Since there were 2 grouding opinions, I went back and ran a wire from the tub directly to the cluster housing but unfortunately, no change. I should add that this is an aftermarket cluster, not the OE unit. The fuel and temp gages do not appear to be grounded; they are plastic and simply snap into the cluster. Also, the fuel gage only has 2 terminals compared to the OE's 3 terminals. It looks to me like it has a solid state voltage regulator versus the OE's mechanical regulator.
Thanks for the link. It has the Ohm specs. The next thing I will do is check the resistance of the sending unit at the block and see if it is within specs. The article says that resistance goes down as temp goes up. I would think that if I had a problem with a bad electrical connection, I would have the opposite problem and the temp gage would stay in the cold range.
