Thank you Mark.

Disconnecting T2m made no difference. Hand brake released, turn key,
 !   still comes on. Battery tested @ 12.5 Volts but "67%" charged.

Re: track 25, I see what you mean. I swapped ICU's last summer. Maybe
cable strapping the ICU (on its side) to the intake snorkel duct put
it in a poor position? Allowed moisture in somehow? I doubt it, but
will disconnect the ICU and try again after battery is fully charged.

FWIW, I have swapped ignition switches yesterday. This was with a used
switch but it made no difference.

I thought maybe I'd disturbed something at the fuse box or near by
when doing previous unrelated wiring, (headlight upgrade etc) but I
see nothing disconnected, singed, or otherwise. It ran fine after that
wiring was done.


Neil.
