Battery voltage across the posts is 12.58 volts. The wire to the points is landed on the - terminal on the coil as is the condenser wire. The + side of the coil has a black wire on it that disappears into the harness behind the starter generator. When the key switch is off I have .000 volts at the + coil terminal. With the key on engine not running I have 12.55 volts at the + coil terminal. Key on points open = 12.43 volts at - coil terminal. Key on points closed = .16 volts at - could terminal. I did 2 compression checks per the service manual. The 1st one electrically with the starter turning the engine over, with the compression release probably releasing I got 40 psi. The 2nd check I removed the pto guard and wrapped a cord around the pulley rotating the engine backwards like the service manual states. I got 90 psi. It was a difficult pull because of the small diameter of the pulley. The manual states 100 psi is the lowest acceptable reading. Maybe I need to pull the head and check for bad valves or worn rings/bore.
