Installed new alternator,new relays and repaired corred wires still no power to field circuit to alternator and alternator warning light
You mentioned "alternator warning light" if that alt, battery light does not come on when the key is turned to the "on, acc." position the light bulb is bad or the traces leading to that light bulb on the back of the instrument cluster has a break in it. I know this sounds crazy but if that light bulb does not light it does not complete the circuit for the alt to charge!
That is If the case 580sk is like the case 580sm, 580l, or 570lxt.
You should first test your Alt to see if it is good. Jump 12v to terminal D on the Alt with engine running. (may be a different terminal on other Alt) If you voltage gauge shows it charging , Alt light goes out & tach starts working the Alt is good. Remove the jumper wire.
If the bulb is good in your control panel for the Alt light and the numbers on the bulb are 168 check to see if you have 12v on both sides of the bulb with it in the socket & engine running.
If there is not 12v on both sides, here is how I just fixed my charging issue yesterday.
I replaced the (168 bulb, this is the bulb that is call for in the manual) with a 194 bulb.
My tach, voltage gauge all are now working. ALT bulb goes out when engine it running. Alt light is a bit dim but it does work.
This was most likely a engineering problem from factory by putting a wrong amperage bulb in the circuit for the Alt light because I have read some forums about this where some say this was a issue with the 580k from the very start.
Is it save to say the 590 super L is the same way

well yes there is a diagram available if someone just knew exactly which jeep model you have and the engine and transsmission combination.

just put a one wire alt. on it.or test each wire.
SOURCE: 2001 Jeep wrangler not charging. Alternator has
on the field wires ones a posative and one a negative and the single post gets connected to a wire that runs straight to the main fuse box in the engine compartment then is fused to another wire that goes to the battery have that fuse checked it could be your problem as far as the feild wires the positive side only works when you start the vehicle up to engage the field

Alternater has two leads(wires) take a jumper wire and zap the snall wire connection. just zap it, don't hold power to it... injury hazard when around running componants. have engine running when zapping. good luck and be careful
SOURCE: installed new alternator and car battery still will not charge.
did you unhook the battery prior to installing the alternator
