AAU is interchangeable except for 20M3 (opposite rotation).

As per Atlas P11 (behind cylinder barrel)??

I presume so, therefore, the 20M3 etc. AAU needs to be clockwise rotation.

OK if you're refurbing old wiring but he said he bought a new harness.

Personally I’d still do it.

I pretty much agree. I bought a new cloth covered expensive new loom and at the very first connection I tried to make the bullet fell off in my hand. !!!!!!

Curses!!

I put it in my spares box and remade the connectors on my old harness.

I am surprised A-N offers them. By the looks, maybe they are NOS? Triumph Meriden used AAUs up to 1979 (E.I. from the on), so I guess Lucas was able to supply A-N as well.

So, meanwhile back at the original question

How dare you!

Taking us back to the original question will derail the thread ...

Right.
And we where only a few posts away from 'my Seeley' and 10500 rpm Triumphs.
Now we may have to wait for several more days..

Actually it's probably easier to change them all with a new harness than trying to retrofit a harness in place. I have a box of those 4 mm bullets and while they are nice, I wish there was an equivalent size that mated with Lucas bullets. I have all the appropriate crimpers, including one for Lucas bullets.

Yes, it must definitely be easier off the bike.

This looks very interesting, thanks Ludwig. For anybody else who is curious, have a look at https://www.wwag.com/cgi-bin/WebObjects/WebSite.woa/wa/DirectAction?page=!37892

This self-cancelling feature would suit me for the same reason as ludwig mentioned.
The instructions mention the maximum load, being 7 Amps.
Maybe I overlooked, but I could not find information about the required resistance when using LED lamps, say for 2 indicators in modus 7.
Has anyone found out what the required minimum load is to be, to make it work?
