Intermatic Pool Timer Wiring

[sjeffers01]

I found instructions for testing a pool pump with a multi-meter at Inyo Pools website. I will test the pool pump this afternoon. Testing to check for a short across the windings sounds too complicated for me and way beyond my skill level. I don't have an amp-meter. If I have to replace my Pentair 3/4 HP Whisperflo single speed motor, can I buy a 3/4 two speed motor instead? Is the quality of an OEM motor equal to Pentair's replacement motors? I think the pool pump is at least a few years old. I have to see if there is a date on the pump and will update thread if its older.
