2210 won't start when turning ignition key, all I hear is a click. Charged the battery and did a load test with a Harbor Freight tester-registered low on the good scale. Tried another battery and the same click sound. Is there anyway to jump across the starter terminals to test it? I looked at the starter and it doesn't look like the 1960-70's car starter terminals I'm used to. Any ideas out there on the problem are welcome. Could it be the safety switches and how and where do I test them? Thanks, Mel
