Thanks for checking your K40 Terry.

Update: Bought new 'group 49' battery at Sam's - same results (idling voltage remains at ~11V even after 2-3 minutes) - revving the engine does not change reading. Belt is not squealing - I assume it is not slipping since tensioning system spring is not broken. I wondered if the glow plug relay could be 'fused' but not reporting the error code - removed relay and checked for continuity between +12V input pin and all 6 outputs (there was none). I did notice about 9k resistance between ground and each of the 6 outputs - does that sound OK/correct?

From inside the car you would not know the charging voltage is really low - starts right up and there is no indicator light or warning message...
