I sent an email to the led supplier. Never got a response.

The lesson I got from this thread was in real property it is "location location location" in aviation and motorbikes it should be
"inspection inspection inspection". It really does help if you own an old bike.

If you are after a good charge warning light / oil pressure / battery monitor set up - have a look at this site https://www.improvingclassicmotorcycles.com/products.htm
I put one on my mk3, a really good set up and the vendor was super helpful + quick to ship.

FWIW The Canadian MKIII models had/have a special assimilator that in the first main-switch "on" position ran the lights on ac only. No battery connection so the lights couldn't run the battery down. They aren't very bright at idle but presumably you're sitting at a stop light so maybe dim lights doesn't matter. In the second "on" position lights are on full bright and run off the battery.

There must be some sort of voltage regulation inside the assimilator to prevent over-voltage. Maybe a Zener diode but there's no heat sink for that. I bought a new one once but didn't take the old one apart to see what made it tick. Might be potted. It had been bad for years and had no apparent effect on the system except that there were no lights in switch position 1.

Odd. I had correspondence with the supplier (a single chap is the whole company). Took a day or two for responses but there is the time difference and weekends etc to account for. Have you by any chance got a spam filter grabbing his messages?

As the 850 Mk3's RM23 charging system is AC-regulated (by the two Zeners) there would seem to be no need for additional voltage regulation when the lights are running directly from the AC output.



The Canadian ignition switch is also different.

No spam filter error and I did get the address correct. Now it’s one of those low priority items. I have the gearbox apart and concentrating on that.
Thanks
