Hi Charlie,
After reflecting on your email message from a few weeks back I decided to
repair my Lucas 15ACR instead of converting to the Bosch/Fiesta unit.
Unfortunately I had to travel unexpectedly and just got everything back
together---it works great!. Thanks for your input---these alternators are
indeed easy to repair (well, at least the electrical parts).
Details: About 18 months ago (but only ~4000 miles ago) I had the altenator
rebuilt locally (Mountain View, CA). Thus I was only mildly surprised to
find that the parts I ordered from Moss didn't quite match the parts
installed locally. Specifically, the "Anti-Surge Device" was not
installed, so I couldn't just put the new one where the old one was. And as
the main problem with the altenator was brief periods of significant
overcharging (ammeter nearly pegged), it seemed I might need something with
a name like that. I called Moss (Harry Hague?) and his advice made sense
to me---the Anti-Surge Device connects to the "Sensing" input circuit
(labelled B+ on the case, as I recall). There was really only one logical
place to mount it, so that was simple too. I trotted down to my local
parts shop for testing and came away happy.
Thanks again,
Cregg Cowan

PS. I'm taking the liberty to copy this to the triumph mailing list.
