And I can edit the number to the right, <- deletes and replaces with _, 1-9 replaces _, R/S quits with either new number oder NONEXISTENT depending on unknown condition. ED shows same display except for an R instead of D. With EMDIR it shows the SW face (oh, uh, Apple watch has faces, 41 just a display), which I can only get rid of via ON. R/S does nothing in this state. Comparison:My halfnut shows D001, then X with proper number of registers, here 124. All i Can sat is that the 130pF should be under the bundle of wires (between the 2 diodes) in your new picture. I replaced it with 33pf and that was close to 100% nothing on the Inductor |
