The only other thing is a high resistance somewhere which is intermittent
making the battery not have much guts on a high current. Could you, by
disconnecting the earth have managed to clean the connection perhaps?

Well, I think the battery itself is OK. Went for a run Thursday afternoon
to charge the battery, then left it until this morning (Tuesday) with the
earth lead disconnected. Reconnected and an easy start, from what felt
like a still fully charged battery.

To recap, if parked with the battery connected, the battery is almost flat
after 48 hours, as in not enough to turn the engine to start. The
courtesy light switch(es) were suspect, but same thing happens with them
disconnected.

I tried Harry's bulb trick again (small MES panel light bulb between -ve
battery terminal and earth strap), and nothing. Tried using an ammeter.
Nothing. Yet current must be flowing somewhere.
