I picked up a John Deere 575 recently and have been tinkering with it. It works good but has a rough time turning the starter over. I bought a new battery, battery cables, starter solenoid and it still does the same thing - I turn the key and just a single clunk noise. I used to be able to just jump start it and it would start up fine. Now I hook the charger up and set it on 200 amp start and it wont give it enough juice to turn it over, just a clunk noise. In order to start it now I have to jump the solenoid which is a pain in the rear. I know theres a short somewhere because when I hook the charger up and leave the key on the on position the buzzer thing gets louder. Any suggestions on which wires to check or anyone have any suggestions on how to start this thing without having to jump the solenoid? Thanks in advance. Brian
