Sonerai Alternator Regulator/Rectifier

You could also try the 'regulator' from your rotax dealer for the 912 -
altho it's truly overpriced for the crude job it does.

I'd think that an automotive regulator would be the best choice also, if
they can indeed handle the crude output waveforms.

Hi,
Got a little Sonerai that runs a VW 1835cc motor with a Great
Plains
alternator that runs on the Flywheel end of the crank. I had a
homemade
rectifier regulator that is giving problems. I am thinking that
maybe there
could be an off the shelf automotive type regulator/rectifier that
would
suite for this purpose? I tried talking to a number of local spares
shops
and automotive auto electricians, but no success.


I think it's the motorcycle crowd that you want to enquire from. some
bikes use simmilar crude alternator systems that use very simple
regulator systems.

The basic specs a
1. Two wires come from the alternator.
2. Voltage between the two wires vary between 25VAC and 40VAC
depending on
RPM.
3. Also Voltage between each individual wire and ground is between
12.5VAC
and 20VAC depending on RPM.

I have found the test instructions on the Great Plains web site and
all that
tests OK.

Any ideas on what regulator/rectifier would work for this scenario?
And also how to connect it?

Andre
