Well, all done
Wired it all up. Got a jiffy box and a 3pin connector (so I can unplug the Sensor from the Jiffy Box), at Jaycar.
Looking at the relay and the base. I had no knowledge of what spade connection went to what terminal.
Yes, of course the two inverted spade connections were the 'Coil' - BUT - how would one know - for sure - that they connected to those lower terminals?
And yes, the connections run in order, from left to right! But how would I know, having never seen one or used one before..?
As this replay was a DPDT relay, I honestly though that the A nd N would go in one side and the relay would 'pass' it onto the other side...!
Sure it's stupid! But there's no manual and but of course there is the Internet...
Some websites will describe the connections different.
So I have learnt a LOT. I have never had a need to use a relay before. I can see a myriad of uses for them as you George65 have said.
I don't think the missus is going to be happy...
I'd like to say that at this most basic of all posts of what a relay does and how to wire it (onefella), I hope that others learn from this.
Before I go, I'd like to ask one other question about the longevity of this relay.
It causes a spark (points system). How long will this relay work before the contacts get carbonized?
Is there a Solid State Relay that is NC from cold...?
EDIT: This eBay listing 401759993242 seems to say it's NC, but it looks exactly like the three I have here,, LOL! Is it NC or not from cold?
Anyway, It's Christmas Eve - and for all those who are spending it alone - it's hard as I have done for many many years. But it passes and it all starts again in 8 days...
All the best everyone and once again thank you for every ones help.
Cheers,
GT250.
