The history is:
1+ month ago the car started acting up; about every 4th time it wouldn't turn over, though the lights and other electrical stuff worked. There was corrosion on the battery terminals, so I concluded that either they weren't getting good contact, or that the battery was going . Cleaned battery terminals and problem went away for several days. Re-occured, so I bought new battery. Problem could be worked around by thumping the terminals . Didn't have a chance to put new battery in , and then the problem went away completly, so last week I took the battery back . Yesterday problem returned. Car didn't crank; rapped smartly on top of the battery leads with fist, car started normally. Today car wouldn't turn over for wife, her messing with terminals didn't fix. When I got home I rapped on the terminals again and the car cranked weakly, then started. Next time I shut it off it wouldn't crank at all. Cleaned terminals again, no crank. Replaced battery, still no crank. All electrics working, radio, headlights, etc. Headlights do not dim when attempting to crank. Both batteries show 12+ volts. When attempting to start I can hear the solenoid clicking, but the starter motor doesn't engage. Rapping on both with pliers improved reaction to crank attempt marginally- posted
