I have a Diode in there.The problem is if the Diode is left in there without it attatched to a on and off Toggle switch inside the Car the Alternator will not charge or will destrot the alternator.So once the car is started I click the toggle switch to activate the Diode to the Regulator.This was done a long time ago but another reason was that I could not shut off my engine with the Diode in the on position for the whole time.Im unsure about that part but Im sure it affects the Alternator.I went through at least 7 alternator's until I put that Diode in with the Toggle switch on the Dash.
