Took battery to store for check and discovered the helicoil was loose in the positive terminal. The parts guy told me he wouldn't be able to get a valid check. Although the connection was tight in the terminal I figured the loose helicoil might explain the problem so I brought a new battery home and hooked it up.
I did the voltage drop checks and got the following results:
Batt voltage between the terminals - 12.6VDC
Batt Voltage between the terminals with the key in the run position (car not started) - 12.2VDC
Voltage drop between terminals when cranking - 1.1V
Voltage drop between Neg terminal and chassis ground when cranking -.04V
Voltage drop between Pos terminal and starter when cranking -.18V
Batt Voltage between the terminals with the key in the run position (car started) - 14.4VDC
I buttoned everything up and did 10 start cycles with some driving in between. It seems to be running fine and starts right up each time. I'll try first thing in the morning to see if sitting overnight is an issue.
Could it have been as simple as the helicoil?
