Charging troubles

<< < (5/5)

BigAl (Alan):
The answer is No. The regulator is simply switching current ON&OFF to the field coil.
The early CB 750 around KO had a regulator that simply switched ON/OFF the later type (similar construction on the outside) had a mid way position switch

Bryanj:
The later electronic ones tend to charge as a smooth curve instead of just on-half-off but the maximum output does not increase

ST1100:
Obvious as max current is related/limited by the alternator's capacity, but shouldn't the smooth, thus steadier voltage be a benefit?

BigAl (Alan):
Electronic regulators will switch the field coil ON in a curved pattern as suggested...lets say 2,4,6,8,10,12 amps as apposed to the standard regulator 0-8-13 amps, but it is still simply switching the field coil on or part on or off.

When batteries are aging and starting to loose there efficiency they are not as good at receiving the full charge due to the deterioration of the battery plates/electrolyte and also the bridge rectifier not providing a true DC output
