GS Rectifier/Regulator replace

[bitzz]

Could have only been enhanced if there was a more compact version. The series design with auto disconnect already is a massive improvement over OEM.

What is "auto disconnect?"

[Rich82GS750TZ]

Came here to ask the same. What do you mean by "auto disconnect? Are you referring to how the series SH 775 effectively shuts down rather than shunting excess voltage?

Hey Rich, sorry about the potentially misleading terminology.
My understanding is that the shunt regulator shorts the excess voltage and thus current back through the rectifiers and stator while the series regulator will stop conducting or effectively disconnect above the maximum charging voltage.
So the series R/R only provides the current needed from the source (stator) that is required by the load.
It isn't like a relay that disconnects the source for an extended period or hysteresis window, but switches off at peak stator voltages if load demands are met.
For my bike, with normal load conditions and close to a fully charged battery, this appears to happen somewhere between 4-5k RPM. Above this is where the advantage of the SH775 kicks in.
