Cluster Disassembly
#7
Hey! It worked! By tinkering with the adjustments at the top of the oil pressure gauge, I was able to make it read right again. The picture with the gauge at 60 pounds was taken with a variable resister set to 141 ohms, and the power supply set at 14.4 volts. The one with the gauge at 110 pounds was taken with a variable resister set to 102 ohms, and the power supply set at 14.4 volts.
There are two adjustments at the top. The one with the red line pointing to it seemed to have more effect on the zero setting, and the one with the yellow line pointing to it seemed to have more effect on the full scale reading.
It's a good thing I got this one working...the one in the spare cluster I bought off eBay doesn't work at all...and I made sure I asked the seller if they all worked.
