3 phase conversion

Richard Dodds · Oct 6, 2018

Hi guys,
My first post on here, hope it is in the right place.
I have just converted my 1975 Mk3 Interstate to a 3 phase set up, also fitted a 3 phase Podtronics unit

My question is what do I do with the lights on module (Canadian model)
The previous single phase setup had 2 wires from the stator feeding to it.
In the new setup the 3 wires go to the Podtronics unit directly
I have removed all the unused components rectifier, zener diodes also the blue can mounted on a spring.
I see on wiring diagrams the other type of module (warning light) also is fed by the stator wires.
Do I just remove the module and surplus wires, or can it be made to work?
Much appreciate any advice

After removing the OE rectifiers and Zenner diode you can attach the Podtronics output, red if you have maintained OE polarity, to the wires that came off the rectifiers output, or to the Zenner wire, electrically they are the same.

Best wishes.

Welcome to the forum, and yes, your post is in the right place.

You could try connecting two of the stator output wires to the assimilator, that might work?
A better alternative in my opinion would be to fit one of the various modern charge warning gadgets, however, none have the Canadian 'automatic lights on' feature as far as I'm aware although you might not be concerned about that as you are in NZ?

Many thanks for your advice, will give this some thought. I do like the idea of removing the Canadian lights on module and associated wires. Maybe also replace the Canadian ignition key. I have looked at the led battery charging modules mentioned in a thread on here, they look interesting!
Thanks again for your help

Many thanks for your advice will give this some thought, summer nearly here in NZ and bike is running well. Am going to play around with my old wiring loom, then when I'm happy with it I will remove the redundant wires from the new loom I have. Gave my primary drive a good overhaul while fitting 3 phase Stator.
Nobody told me they don't fit easily!! My bike has been making a g
graunching noise on cold start up, anti backfire was slipping at 30ft/lb of torque, setting it to the correct 50ft/lb fixed this problem (after 20y of me thinking it was the Sprague clutch!

I have never heard of a " lights on module (Canadian model). Or the "Canadian ignition key". Anybody know any more?

Canadian ignition (master) switch.

Thanks L.A.B. Not owning a Mk3, I had no idea that the Canadian Nortons used a unique electrical component.

Having researched this topic, it is not clear that the first 2000 (up to 327000 approx) early MKIII had the Canadian headlight-on option possible due to the different harness.

Yes, as it states in the Mk3 manual:

"The former electro mechanical Lucas 3AW (Warning Light Simulator fitted on early electric starter Mk III models) has now been replaced on all models (except Canada) by a solid-state encapsulated Warning Light Control 06-6393." as the legislation applied to Canadian machines manufactured "after 1st January 1975" therefore not the first approximately 6 weeks of Mk3 production (which began mid-November '74 according to Joe Seifert).
The Canadian legislation possibly being responsible for the change to the 'solid-state' (06-6393) warning light 'assimilator'.

If I read and interpret this correctly, the first 6 weeks production only had the 3AW WLA. The following production (after 327000) only had, either Canadian headlight or 06-6393 solid state WLA.
Are we on the same page?
For me it was difficult to tell since I only was able to update a late model schematic to try and document the early bikes.

Yes, assuming the manual information is accurate then the Canadian lights-on requirement began on 1st January 1975 (although I'd be reluctant to put an actual serial number to it but probably would've been somewhere around 327000) and if NVT hadn't been forced to introduce the Canadian 06-6392 lights-on unit then I think they might well have continued fitting the 'silver can' 3AW but instead changed to the 06-6393 WLA so the same harness section (06-6396) could then be used (with wires included to suit either unit).
