I suspect this capacitor, C1, was previously replaced. What are the values stamped on the capacitor? It should be 1uF @ 50V.

These solder joints are new when compared to the rest on the board. The components above were replaced before.

Red cap points to the solder joint of ZD4. Note its separation from ZD5 and ZD7's solder joints. It is normal for the solder joints of ZD5 & ZD7 to touch. They share the same electrical connection.

Here is C3 soldered back in place. I ensured solder was on the top side as well. This remove and reinstall did not fix the odometer.

C3 removed. The negative lead hole (on the left) looks a bit tarnished from the original cap leaking.
