Just completed an engine swap from a 12.5hp to a Briggs 16 hp Vanguard.Swap went fine but have not hooked up the charging circuit yet.The engine is model 303447 and has two red wires coming off it,1 to ignition and 1 from the rectifier/regulator.My question is why do I not get a voltage reading on the rectifier wire? Thanks for any help on this.Gord
