Diode

Hi All, what can happen if I donít install a diode in the charging circuit on a B&S Vanguard V Twin? It seems to be charging OK

The battery will most likely discharge when the engine is not running. The diode prevents the reverse flow of the electricity.

The diode converts AC to pulsating DC current in this case .

Not only will it discharge the battery, it will fry the stator and/or wiring to it. Possible fire risk.

I donít understand why if the engine is equipped with a regulator/rectifier why is the additional diode necessary, Kohler engines do not show a diode in the charging circuit but there is a option to install one in the kill switch circuit.

I'm not familiar with any of the ones using a regulator/rectifier also using a diode at the same time. I didn't know your engine was equipped with a regulator. Some briggs twins don't have them. Why are you asking about it, does the book show a additional diode in that circuit on that engine?
