I bought a rectifier from someone out of state, and they sent me something else. The rectifier is small and triagular shaped. What they sent was the item mounted on top of the engine, between the heads, sorta under the flywheel. It has 1 heavy wire going to one side and 3 or so smaller going to the terminal strip on the other. Also the circuitry is incased in a rubbery epoxy (3"x6"). What is this item. Can't find in my clymers manual anywhere and is it expensive?
