Ahhhh, got it! When you said "the cathode would be at the top in your schematic", you were referring to the top of the diode - I thought you were talking about the top of the diagram! Now I understand.
Thank you so much for taking the time and trouble to help me. I assume this is pretty basic...
OK, so I believe this circuit is now correct...
But, and please excuse my ignorance, I understood that cathode = negative and positive = anode. As the vehicle is negative (cathode) earth, surely the cathode is at the bottom and the top +12v supply from the battery is the anode?
Now that you mention it, I remember something about a diode. However, I can't claim to understand what it is or why it was included in the circuit. Now that you've explained, I think I understand. Is this correct...?
Hi, I'm new here, please be gentle. I'm also a complete novice, so apologies if I'm a bit thick!
Some years ago I bought a commercially available car immobiliser which used a latched relay. This proved so successful that even when I exchanged my car at the main dealer (and explained the...
