RE: AM12U Appliance Module

["Brian G. Reynolds" <brian.g.reynolds@xxxxxxx>]

That's the picture I remember, Thanks Keith.

Is this a problem, apart from the cosmetics issue of showing on when
actually off?

Could I fit a larger resistor on this LED to hide it although it still will
have power, or can/should I cut the 2K2 resistor somewhere?

B. out of his depth again but learning...
