Resolution: Hi shield at outer probe has a tiny amount of conductivity to the Hi-Z wire.
traced to the last probe shield termination. Squeezing the term-a-Shield changes resistance.

At power up, RH 500 hi
After 10 min, boost pumps on, all equal?????
Initial:
Rh gnd-sh dead short
Rh glm
Rh glf low at 1000
Rh shm 500 wiggles!, left side side good.
Rh hlf 1000
Low gnd half scale
Lh: gnd-low 700m
Lh gnd hi 3000M
SL 700
Sh 3000
Sh 3000M. Good.
Turns out, the Shield to Hi on the right wing would vry from 300M to 1G Ohm. RH OB probe shield termination was conducting a little.
results after repair:
