So, I was changing out the lights in my instrument cluster (87 GL Coupe, EA82 Carb, originally automatic, converted to manual), worked great, no issues. All the gauges still worked, the only thing I unplugged was the speedo cable. So, I put it all back, went to move the car, and noticed the gauge was pegged (full), so I checked to make sure I hadn't bumped it, like I've done on the coolant and oil guage, but it's range was still normal. So, I turned on the car, and it didn't change. However, if you move the gauge, by hand, to the "E" side of 1/2, it will fall to that side's end of travel. If you move it to above 1/2, it will rise to strait up (past full). If you get it really close to 1/2, it stays put.
I checked the wires, to see if I had bumper them, they all look ok. I jiggled it around, no change, so I tried unplugging it (the connector), and the gauge goes all the way up, from where ever the needle starts.
Any ideas on what I might have done to it?
Note: I did try searching, but didn't see anything similar.
