harness koeo 1&2 0 1&3 4.86 2&3 4.62
harness connected, k on 1&2 0.10 1&3 4.79 2&3 4.68
after I shut the key off and retried the same test I got no readings at the harness disconnected dont know why.
EHA dc 20 kon got a 1.38
running .09 to .30 cold eng.
ma .16 to.43
both readings fluctuating rapidly
EHA never below 0.08 at 2.5k

I should have looked here first, just sent you a proceedure on the old thread.
Wow data overload
The pot switch is really a potentiometer -a variable resistor. The resistance changes as the plate is sucked down into the air horn. Read ohms and push the plate down. It should be a smooth change with no dropouts all the way. There are some pic on other threads of the insides and the resistance film can wear through, one guy just moved the wiper over to get new film and a temp fix.
Great! "EHA dc 20 kon got a 1.38, running .09 to .30 cold eng. ma .16 to.43" Sounds like you got the meter in the circuit right and you are getting a positive .2ma =-.1 cold engine, .3+-.1 warmed up?
"both readings fluctuating rapidly, EHA never below 0.08 at 2.5k" Expect that. Its not adjusted right. But great you got the data!
Now read my long thing at the other thread so I don't have to explain how to adjust it here. Simply: Adjust the EHA 1/8 ccw and see if current goes up or down. You want it to go down and end up at 0+-.1, Then readjust mix to 50% check 2000 mix and idle rpm.
Isn't 50% charging voltage on pin4 ~ 13.8/2=6.9V?? There is a thread on this, may be DIY. I've been using the dwell meter not the V meter.
