Hey Magnus, thanks for the picture! And with a small file size too! (I'm on a dial up line) It still took several minutes to load, but a picture is worth a thousand words. What I'm looking to learn here is exactly how the accessory circuit is energized. The schematics I'm finding tend to be half pictures, and especially the connectors tend to be very ambiguous about exactly what goes where. And the way they're organized and grouped power often just mysteriously appears from somewhere off the page, with no depiction of how it got there. So anyway, if you turn your key to the accessory position, (if your radio isn't on already) you can hear a click from the voltage regulator. The accessory wire off the ignition switch runs there, and from the schematics looks like it drives a coil pulling down a set of contact points. That would be the "click". Here's where the schematics get especially sketchy. That relay must energize part of the fuse block then, to drive the components on the accessory circuit. That way all that power doesn't have to go through the ignition switch. I think. Anyway again, the coil in that accessory relay must be very low voltage tolerant. If you leave your radio on, it runs down to pretty much nothing if you let it, the coil doesn't "let go" as the voltage drops. I suppose it might not latch with too low a voltage though. From that picture though, it looks like that relay function is pretty intimately tied up with the regulator functions, but I'd need a closer look. Time to stop typing and start looking.
