Re: Converting to a 12 volt alternator – mission completed
I did not use the original dynamo drive.
In fact the whole module is new. The body is machined from a solid aluminium cylinder; the shaft is steel.
Yes we do lots of driving in the dark, especially now at winter time when it is getting dark at 16:30 already.
Also pls note that riding here in Israel with lights on is mandatory 365 days a year 24 hours a day, even in August at noon with 35 Celsius :sunglasses: .
You can see that I later switched from the v-belt to a toothed one. Saved some space this way.
Yes the clutch of the magneto slipped a bit, but tightening it solved the issue.

I used a dynamo body fitted with the drive end casting at both ends and standard dynamo bearings..I then made up the shaft that took the dynamo drive gear at one end and the pulley at the other...Ian

Re: Converting to a 12 volt alternator – mission completed
Hi Ian,
You asked for the output of the Alternator.
It should make 14V / 14A, which is almost 200W.
There is a similar model which puts 20A. (280W)
"Alton" states on his products:
"While running at moderate cruising speeds they supply an output of 85 to 90 watts
(maximum output of 150 watts)"
So 200W is much stronger,
But if pushed to supply what it can, and not keep the Amp consumption low,
I am not sure what all of the additional stress will do to the timing drivetrain and the fiber drive gear,
which were initially planned to push 40 and then 60W of stress.
The project and the work and thought put into it are commendable.
Michel-
From experience, you might want to put an NO-OFF switch on the lead from rectifier/regulator to the battery,
As there is usually a slow drain to the electronic regulators,
Which unlike the mechanical ones for the dynamos, do not have a physical switch ("Cut-off")
And the battery charge seeps back into the system through the diodes,
So in few days (Max) without charging, you would find that the battery is flat...
