Oh, you weren't kidding. This project might be too advanced for you. But I will break-down my slap-shod, napkin-spec wiring diagram for you.
>what are the other circles in the drawing?
That's just how I denote a physical connection point. E.G a wire gets soldered here.
> Is the diode at bottom left a heat sensitive diode
What even is that? No it's just a standard 3A diode. It protects everything in that circuit from the back EMF that the relay generates when it is switched off.
>What's the A1 box
It's K1 (napkin tier drawing) it's just the coil of the realy, applying 12v to it will change the state of the relay.
>what's the dashed line going up from it?
That's how I draw a mechanical connection, saying the coil K1 of the relay moves the two switches the dashed line is connected to
>If 1 and 3 both go to 12v, why are they in separate wires?
Terminals 1 and 2 are connected to a constant 12v supply, this never changes. Terminals 3 and 4 are connected to a switched 12v supply. This voltage is switched on and off by the timer relay.
Terminals 1 to 4 down the left side of the drawing are all inside a 4-pin connector in my setup.
Before anyone else says my electronics are third world, I am a mechanical tradesman not an electronics graduate. It still gets the job done and has been working daily for nearly 6 months now.
