I recently purchased a (sv470-0111) Kohler Courage 15 hp electric start engine for my bobcat 48 w/b. I am having some problems getting it to start and was wondering if any one could help. Do I have to connect the battery to any thing other than the starter and fuel solenoid to get the coil to produce spark? I have the Kohler service manual but on my engine there is a extra thing that looks like a relay and it reads "coil 12 vdc". This does not appear in the wiring diagram that I received in the Kohler service manual. I'm not sure what it does or if it needs voltage to help produce spark. Any help would be greatly appreicated.
