Hello Folks, I have a Case 580L that will not start without jumping the starter solenoid and once running, will not go forward or backward. I believe it is an electrical issue. There is a hard short in the #3 power relay circuit. It instantly smokes a 30 amp fuse for the "rear work lights" even with the harness to them unplugged. I have looked the machine over pretty good and have unplugged quite a few plugs in attempt to find the problem. Wiring schematics for this machine would be very helpful. Anyone experience an issue like this or have any ideas, Thanks in advance.

I have the service manual for a 580L Series 1.
PM me your email address and I can send you a link to my Google Drive and you can download it.
I do not see an Icon anywhere to send a PM. Do I need to be following you to do that? I tried starting a conversation with you, I'm sure if that worked.

Tinkerer,

I have a 580L series one. I thought the alternator was out and bought a new one. Still not charging. I am not getting any voltage to alternator to activate the field. I have no wiring schematics. Do you have any suggestions?
