Ok so one brown and one green wire go from the VR into the alternator loom. The other green wire goes into a connector and three other wires a black one for the split scharge relay, a red one which also goes into the alternator loom and a blue one which pops off towards the front of the van and is connected to the little connector in the bottom pic. This is then (for some reason) connected with chocolate block and another green wire into the loom.

I've also got a random connector on another wire from the alternator loom, it's the brown one over the oval vent in the top pic. That wire and connector has been knocking about loose in my engine bay for about 8 years though.

Have you measured the voltage at the wire that goes to the light / split charge relay yet?
Also, disconnect the wire at the split charge relay and see if the light works properly when revved.

That first one was useful Barn, especially when the guy said he'd fixed it because it was a dodgy earth. The symptoms were exactly the same as mine AND I've been playing about with the earths from the battery and gearbox.

I'm going to do that in the morning. My battery is shagged and I've been messing about jump starting it. I've ordered a new battery from Tanya which should be here in the morning. looking at the top pic, which wire is the feed for the ign light, is it green - blue - green one that ends up heading off into the main loom

Over time the blue alt. wire goes a bit green.

In my experience of a couple of broken regulators, the alternator was putting out 17-18v but the dash light didn't come on whatever the revs because both wires to it were at 17-18v. So to make it light must mean battery is at it's normal voltage and the alternator blue wire is at reduced voltage? As you measured the alternator main output at the battery at 13.7v or whatever through the revs, the alternator seems to be working which only leaves the whole thing being a figment of your imagination. Hope that helps.

Just been looking at one of Barneys links and it speaks of checking the warning light wire which, it says, goes onto contact WL or IND, neither of which my regulator has. I have D+, D- & DF.

I have D+, D- & DF. warning wire should be the only one joining the main loom. You have a good collection of joins on it, I'd clean those up, particularly that one clinging onto what must be a weeny bit of wire poking out of the loom. Don't break it.

I'll crack on and split the loom apart in that area and sort out a better contact then get it started and take some more reliable avo readings.

I'd try what the pope suggested too - disconnect from blue wire to leisure split relay and see if that helps. The pulsing is weird, but we'll ignore that for now because once light is out it won't do it!

Not that this pic is a huge amount of help but are you sure you have the wires in the right place? Do me a better pic, and it looks like you have the wires correct.

I'm getting really pissed off with this now, bloody van. I pulled the covering off of the loom as it goes through the firewall and found two thin green cables which disappear up to the front. I jump started it and did some avo stuff and the cable with the three wires going to it gave anything from 13v to 18v as I increased engine speed. the connector beside it started at about 5v at idle and decreased with an increase in engine speed. i took a bit of a punt and swopped both around and checked the ign light which was still on so I revved the engine and the ign light got really bright and then blew. So so now I need to take the dash pod off and fit a new bulb. im shit at vehicle electrics so I'm good at copying what's there already so I'm fairly confident that I didn't inadvertently swop any connections at al so I'm at a complete loss as to why a simple battery cable change could have messed it all up so much.
