Once again I agree with you and I must mention that I avoid to disconect the switch between the engine and the regulator while the engine is running. I´ve only fitted that to be able to select, prior to starting the engine, whether I want to charge my batteries or not and this way have the hability to keep the regulator from having to be dissipating when there´s no need for it.

Nevertheless, the selector switch which routes the circuit and selects between RUN and CHARGE modes can be switched on and of at will, provided that the ALTERNATOR/REGULATOR connection is not interrupted.

I have not tested it with a scope (for not having one available outside work) but I did test the circuit in use hundreds of times and, like you, I have no reason not to believe that this regulator/dissipator arrangement isn´t able to protect the rectifier from any transient phenomena.

Regards
