Yes , the regulator I designed is about to be introduced by CDRC in a month.
No, the field is not driven above the system voltage, just through a FET with
a fairly low RDS. The FET has some special stuff to get it to turn on at a
fairly low dynamo output
On my reg, I seem to get to a charge neutral output at night with headlights
on at maybe 1200 engine RPM
Ate you sure both your field coils are working properly.
On my test rig I don't have the ability to slow down the driving motor. I
will have to check this out on my car to measure the exact RPM to get charge
neutral with EVERYTHING on
