If you already replace the rectifier/regulator and it still reads 17.5vdc, there is something either wrong with your meter, or you got a bad regulator. Make certain all the wire connections are both clean and shiny metal, so there are no possibility of corroded connections. If you still read 17.5vdc with a known correct reading meter, then you got a bad regulator. Also post the year, model and serial number of your engine. JMHO!
