I have a 520 and have replaced the wiring for the Kohler engine since it was rotten and rewired everything up to the ignition switch and I stil have a dead short. I am looking at replacing the alternator/starter. Is there anything else I am over looking?
I have ordered a service manuel but that won't be here for 2 weeks. Does anyone have a wiring diagram for a Kohler powered 520 that you could e-mail me?
