Looks like Greeves ran out of Brown wire

Default Progress??

The headlamp switch is definitely wired as per 25DC and 25DD MK2 (4T Engine East Coaster) and Essex diagram

However that diagram only has a 5 way connector and my one has a 6 way

The yellow being the extra one that goes to the negative side of the battery and up to terminal 1 on the switch


Therefore


Assuming that it was running then I can forget about the blue and green as they go to the coils.

The red and black go to the new rectifier (ac)

Purple definitely goes to 3 on the switch

and leave the yellow as it is - which becomes black to the battery negative and terminal 1 on the switch?

Try it and see, it should be OK. Just check that the charge rate is sufficient when lights are on, & you should get about 2 amp charge with them off.

I have found this diagram for a 2T engine (with 6 pin socket) as fitted to Fanny Barnett Cruiser 89. The bike wiring & switch is different from Greeves but it shows the connections back inside engine casing to the coils

Default Conclusion?

The wiring harness is that of a 25DC and 25DD MK2 (4T Engine East Coaster) and Essex.
Perhaps as the bike was to be an East Coster (although in fact a 32DD) they used existing East Coaster harnesses. This caused a slight difference as the 325 has a six way socket not 5, hence the wiring of the plug in a slightly different order. Maybe someone knows why the wiring was done this way?

Anyway off to Stafford tomorrow to look for a horn for it - anyone got a wind tone Mixo horn lurking in their shed

I think you are right a left over UK East Coaster. I think the extra wire has something to do with the rectifier being 1/2 wave or full wave extra connection on the latter.

I've a feeling you can buy these horns new. Try Googling it.

I think 6 volt ones may be a bit difficult, but do come up on eBay from time to time. I a found a 12volt one and modified it inside (weakened the spring) There is a second hand one on the net in France @ 75 francs which looks like the one used on EC https://www.thesamba.com/vw/classifi...php?id=2019713

I now have a horn sitting on a members shelf waiting for me -
The mudguard and chain guard have both turned up, both in really good condition apart
from the bracket which was not very well spot welded and has become detached.







Was that normal practice to paint the items then spot weld together after?

Default Weld before painting

Certainly looks like it was painted before welding Tony.for spot welding you would need to leave spaces to weld and still have to paint
