HV wire wrap and HVTB testing


I have done the first iteration on the R1 HV wire wrap bus. It is possible to do this wire wrap 2 different ways, but I think only one will actually work. Looking at the attached pic, you can see 2 different patterns. I actually did not notice this until I finished all 7 buses.
The bottom row field wires, F1 and F2, (rows 2-3 in the pic), and F5-6, have the correct wire wrap. The other rows may have a smaller gap between the field wire wrap and sense pin boot connector. R1 may be tricky at first, so we will have to perform extra QA so we get it right the first time.


I redid the wire wrap and outlined the instruction on how to perform this task, see the pdf files below.

    Current draw was just detectable using the Bertans on the 100 nanoamp scale, meter indicated <10 nanoamps current on the analog scale.
