Fluctuating Gauges 240z

[Phil Z]

I have a 1972 z that sat in my garage for 25 years. ( I know! Why?) Last year I got it running and driving. The problem I developed with my gauges was that when power was first applied at startup, the fuel gauge would respond then slowly drop back to E. I could not find anything wrong with the sending units. After taking apart the gauges I found that there was a poor connection between the tiny wires that heat up and make the gauges register and the studs that connect to those wires. The easy fix was to clean the contact points between the stud and the tiny wires, then soldered them together. Hope this is helpful anyone with similar problems. I soldered the fuel, oil and temperature connections and they all work perfectly. See picture.
