4850 Dash Issues

I have a 4850 with some dash issues.
When we got it the dash wasnt working properly, had it sent to Ag Express to repair. The side with the digital tach could be repaired, the otherside could not. Found one at a scrap yard, plugged it in and now i have more issues. The tach doesnt light up at all, the gauges on the left side work to a point... The needles for the voltage and the Fuel gauge move a little but go right back to resting. All however light up on the left side.

where im at now: The testing and reading ive done on forums and what little information deere provides and that i could squeeze out of technicians is that due to the HI beam light coming on when the key is turned is that i have issues with the Investigator II system?
Now is this something within the that module that I can replace or do I have to send that one out to be repaired as well?

any help is appreciated and if I wasnt clear (I blame it on my lack of knowedge with John deere equipment), I can give you my number and try to explain it further!
Thanks!
 
I have a technical manual for the 46 and 4850s. Theres a few schematics in it but none as far as I can tell for the gauges or whats there for the gauges is only for the lighting system or aux lighting.

Any links to a place i can get schematics for a 4850?
 
Well, I got it fixed. Im not sure I missed it but i was testing the Circuit breaker panel again, they all had proper voltage to begin with but I saw a small burn
mark next to a wire, removed the wire, removed the burnt appearing section, got a new connector and heat shrink on it and once all back together the dash worked
as it should have. Not sure what the wire running to as I didnt trace it or have a schematic to trace it with.
