bought this steveco 90-66 potential relay on ebay "new" but sold "as is". kind of scary... I'd like to TEST it, as best I can, with what I have here "so far".
and what I have is the relay itself, an LED test light "continuity tester" I made, that runs off a 'wall wart' (which works fine, it's a good continuity tester). also have other test leads that I can get 120 VAC "wall juice" out of, and another (bigger, range cord, actually) test lead I can get 230VAC out of.
clicking small images should open the (1024 x 768) LARGE version of same
so, to test this steveco "for functionality", I guess the 1st thing to do is
1. with no power hooked to it, use the lite to check continuity between pins 1 and 2 (which should lite the lite)
I don't have any run or start caps here yet...have some electric motors, but they're 20 miles away. no meters.
2. what next? maybe hook 240VAC power across pins 1 and 5, at which time the 1 to 2 contacts "bridge" (the normally closed contacts) should OPEN?
do I have the procedure above right? is there a *better* way to test this thing? I'd like to make sure it's a *working* unit. this steveco will eventually become part of a rotary converter I'm building....
*thanks* for any advice or tips you guys provide
ps-I posted in the HVAC forum instead of the gen'l electrical forum because I figured HVAC guys would have a *much* greater familiarity with potential relays, generally
