I then pulled the instrument cluster, which I really hate doing on this model, and pulled the clock out of it. Removing the two 100 uF 16V capacitors, one measured 25 uF and the other 8 uF. Not good, and no surprise the clock wasn't working well. The drive current for the stepper motor goes through these. I replaced these with junkbox items that tested good, probably the last two I had, and reassembled the clock. It seemed to work fine on the bench, so I put it all back together. Not fun.
