Above is the wiring diagram for early model Penguins with a Huf brand ignition switch that pushes in and turns right for reverse, the one below is for Beavers and the later model Penguins with the ignition switch marked "FP727" that turns left for reverse. NOTE - these both show a light indicating reverse which is not used on Penguins or Beavers, instead they use a light indicating neutral which is wired to a contact on the side of the transmission. ALSO NOTE, these diagrams are for the engine and Dynastart only, wiring diagrams for the complete vehicles can be found in the files section of the FaceBook page "Penguin Amphibious ATV's"
