Hi all. On my series 2 ('88)when I fill my fuel tank right to the top, my fuel guage only reads 1/4 full. And my temp gauge at normal operating temperature is just above the very bottom White line. I have swapped my instrument cluster and it's still the same. Does anybody know what the voltages should be at the connector? And at which pin? I don't really want to have to drop my fuel tank to get to the sender if I can help it lol but the two gauges must be connected in some way. What's going on? Help!!!!
