Point is - with 510 connected across "OUT" and "GND" pads - multimeter shows Resistance correctly - however eScribe and board show no Resistance - "Check Atomiser".
Double and triple checked Grounding - both B- and GND pads continuity checked - board powers up - Escribe sees it - so B+ is ok . . . Reads voltage on Battery ok . .
Opened a Ticket now . . . Hopefully the boards' not Borked !
