Sometimes the manual doesn't have all the answers

Look in the control panel. The plugs are on the Bottom of the control panel.

First take the wire off K8-3, and measure from there to the Burden Resister. If you get nothing, then unscrew P6. Look at the schematics to see what pins to check in P6/J6.

P6/J6 can also be loose, or have a bent/burnt pin. Open the lower door s lay on your back with a light and inspect.

Ok. I found the smoking gun. I removed both wires from terminal 3, K8. Wire 166B goes to J6-3. Wire 166C goes to R12-1. I unplugged P6/J6. R12 is open circuit. R13 is 7.9 ohms. Double and triple checked readings. Seems I need a burden resister. Thoughts?

I checked with them and it is not stocked. Posted in parts wanted.

Maybe check the solder joints on the R12, might get lucky. Chase the resistance from 166 to R-12 & from there to P6/J6, maybe a wire is broken. JMO

Great minds think alike. I checked the continuity of the wires from the resisters to K8 and , I think it was pin 3 of P6. All good there.

I also checked Ebay. Lots of resisters but none with 7.5 Ohms. There were a few 10 Ohms.
