I bought a Rectifier from seiler marine for my 1971 60 HP Evinrude. While it looks the same the wires are two yellow and one red. my original rectifier has one red , one yellow and one yellow with a grey stripe . How do i go about connecting these ? or does it really matter in the yellow wires case . I have an original factory service manual and it just says the color of the wires.<br /><br />Thanks ED
