One half of 1 meter on climate control panel illuminates. You can press on the left half of the face, and it will come and go.

No illumination on any keys at any of the 3 FMS controll heads

Run each test with only 1 gen online, 50 to 100 amps load, try to hold conditions quite similar for each test.
some other thoughts:
look at big E terminal, small 20awg terminal.
double check each GCU voltage. Is it stable at 28.5? is it stable with load? is it stable with RPM change?
select cockpit red switch to off. Is the voltage of a running generator, cockpit switch selected off, .7v to 1.0v at idle? this checks the quality of the permanent magnets inside the Generator.
ASSURE that NO ENGINE GENERATOR has a cooling fan installed. (possibly a borescope through the black sooty outlet.) or it mat be necessary to unbolt the cooling exhaust.
#3 Gen Light occasionally, Much troubleshooting. Gen 3 amps tend toward zero. #1 seems to “take the load”
#3 gen troubleshooting, #1, #3 gen shunts…..?Removed?
