moe1965 718 #1 Posted January 15, 2023 (edited) I purchased a new rectifier but there are no markings on what wire goes where I know two of them go to the AC side and the other goes to the back of my key switch marked R. Unfortunately I do not have the old one to look at which did have the markings but for the life of me I can't find it... I think the two circled in red are the rete marked AC. Thanks in advance Edited January 15, 2023 by moe1965 More info 1 Share this post Link to post Share on other sites
squonk 38,908 #2 Posted January 15, 2023 (edited) Two leads side by side (red circle) are AC Power from stator. It doesn't matter which wire goes on either terminal. Terminal by itself goes to the switch. Edited January 15, 2023 by squonk 1 1 Share this post Link to post Share on other sites
peter lena 8,050 #3 Posted January 15, 2023 @moe1965 don,t forget to enhance the mounting bolt point for grounding , usually engine to frame corrosion and metal duct work are weak areas for ground ,suggest an alligator clip test wire from battery ground cable ground bolt to that rectifier mount bolt , area on initial testing . if that ground makes your amperage gauge stand at attention , and charging is solid , thats what you want . don,t count on original ground areas , too erratic . pete 1 Share this post Link to post Share on other sites

moe1965 718 #6 Posted January 20, 2023 I got mine on Amazon for $31.00. This is what was wrong with my issues. I also found out PO switched some wires around which probably burned up my old on . 1 Share this post Link to post Share on other sites

moe1965 718 #8 Posted January 22, 2023 I took the part number off my old rectifier and Google searched that to find my replacement. My tractor has a Kohler engine on it. I would say you will have to research what is specific to your engine being a brigs and download a wiring diagram and trace each wire to make sure it's all connected to the correct terminals etc...
