Unless, of course, this mysterious fuse is somewhere other than in the

Ah, no, the blown fuse was in my motorcycle fusebox. The previous owner
hooked up heated grips with a lead (just a length of wire) from the
dashboard power circuit. I blew the fuse to that circuit.

The 12V plug is a normal car cigarette lighter socket for plugging in a
GPS, tire inflator, or heated gear.

Ah, ok, thanks. So. Just re-read the symptoms, and it makes sense.
With a proper fuse in the circuit, you get what you expect. You are also
getting what you would expect with the blown fuse. Except for one thing,
you said you disconnected the heater circuit.

Was the heater circuit disconnected for both measurments you made? In
that case, I wouldn't expect *either* measurement you made to be as
measured, unless there is some other (possibly but not necessarily high
resistance) path to the battery return.

At any rate, sounds like it's working, and just a matter of curiosity.
I'd look for some other circuit off that fuse. Got an electrical diagram?
