hell no. that's not how a Zener works. the Zener works as a switch that turns on at the Zener voltage. they are not voltage regulators on a stick. so what would happen on a 12v bike with a 6v Zener inline. the voltage would be 12v at the Zener. its a switch that turns on at 6v and is off below 6v. what is necessary is a constant 6v voltage. this is done by using the properties of the bjt (old fashioned transistor) with the Zener as constant voltage.
the 6v British Zener regulators are really antique and are not available for cheap. these were wired as shunts. I want 10a for an output that's whats up with the cheapo bjt 10a transistor.
you should use the proper r/r and a cap.
