1973 Ford 2000, gas. Starter solenoid clicks rapidly when key is turned, starter does not engage or turn, battery fully charged. Pull starter, check w/ ohm meter and read 0.00 ohms between frame and positive stud. Huh. Thought there would be a little resistance here. Pull out jumper cables and place neg on starter body, positive on only terminal on starter. Connect to good battery and makes starter hums a bit, meter shows over 200 amps drawn. Ok, bad starter, order a new one on eBay. New starter exhibits the EXACT SAME symptoms as the old one. What are the odds, but I convince myself I bought a bad starter. Return it and buy another from different vendor. It arrives, and yep, same symptoms. Take this one to the local auto parts store, they bench test (computer controlled fancy tester), and IT WORKS! Get home tonight, and it does not work. I now know I must be an idiot and that you can"t connect a starter directly to a battery and get it to run...or am I? HELP - what am I doing wrong, or what other test can I do. My grass is now 10" tall and really needs mowed! Thanks in advance. Jim
