That should be simple enough, given enough information. What voltage, ac or dc, and current is powering the coil of the relay, and what current and voltage does the relay need to switch? Do you perhaps have a circuit diagram, which shows how this relay is installed?

Forward planning, would have made that so easy.

I did think about it, when I sold the Viffer, but its storage space is now occupied by my mobility scooter. Besides, it occupies me enough already, looking after the house, car, caravan, scooter, and tractor.

My mother - a proper, entirely home cooked Sunday dinner, always beginning with Yorkie puds, an occasional evening rabbit stew with homegrown tasty carrots. I've only once had rabbit stew since then and it was horrible. Sometimes, she would make a meat and potato pie. Years later, she would...

Nope, not at all!

Lag only where the pipe heat loss might serve no purpose in warming a space, or where less warmth is needed.

Spot on!

That is similar to my recollection, I remember buying an early Nokia, in around '93, on Orange. The weird Orange TV ads, just mentioned 'The world being Orange', with no explanation of just what was orange :-)

I did similar, except with an 8080, and static ram up to the limit of a massive 64k, but wrote a rather clever word processor, in BASIC. The BASIC, rapidly ran out of ram, so I ended up having to design a 'memory paging system', a sort of precursor to what the BBC eventually made good use of...

To a large extent, yes! The spring pressure, would take up any slack, from the lead deformation, whereas a screw terminal would simply remain lose, until someone came along and tightened it.

Lead, is much more 'fluid', than copper, or brass, both of which are much more resilient to deformation.

We've been in the garden, all morning, painting, drilling, modifying the lounger thingummy, to make it higher, until it got too hot out there. Came in and I'd missed a call from hospital, three hour before. I was just about to attempt to ring them back, when they rang me... They were making the...

I never got to 'play' with it, but my uni had an absolutely magnificent beast of an analogue computer, in a large, polished wood case. I'm not even sure anyone there, knew how to 'drive' it.

And then, was roughly when I built my first 'computer'. All I remember of it was a rather crude display, and a crude hex keypad, but a computer, you could program with instructions. What I built later in that decade, was very much more advanced, and ended up as an S100.

He did say, it went flat, whilst stood, but... Connect a dc 20v meter across the battery terminals. Engine off, it should show maybe 12.5v -ish. Start the engine, it should show 14.0v/14.5v. Turn everything on, and it should still show close to 14v.
