Relays

So i am able to get tons of these relays but they dont come like a standard relay with the 87 30 86 etc... So i was wonder if some of you guys would be abale to look at these relays and be able to tell which post may be what... One seems to be like a spdt relay and the other like an spst relay. Just wondering what post could be what.

New one for me....

Any mfg info on it? No diagrams on base?

Indicate that control voltage is 12-14VDC or 120VAC ?

Just a guess from looking: Ohm-out between the copper spades and u shud get an "open" or "OL"

Pinch the contacts closed manually (appears u can do this in pics) and it should read a short.

If so, this is your coil connections, @ control voltage... and , if so , u can test the silver ones the same way to see if they are NO or NC sets of contacts.

Or just power that bish up wif 120 and measure fast, lol

agreed. you need to know coil voltage first and foremost. you should be able to find out from "work" or whatever source you have.

then, the DMM will tell you everything else. the coil resistance will be between 60-120 ohms (typically).

You should be able to physically identify which terminals go to the coil and contacts. An ohmmeter would confirm. Operating voltage is unknown though.

They are denso automotive relays 12v... i may have figured it out by playing with it a little on a 9v battery, but i will play around with it a little more to figure everything out for sure
