what'd i do?

[Linus Toy <linust@mindspring.com>]

actually, i know what i did--but is the problem (below) relate?  if so, how
do i fix this?

had a mind slip last weekend...left the parking lights on mid-day (tunnels
on I-90 here--should look at the speedo now and then :) then didn't use the
car for about 36 hours...very flat battery.  

charged up the battery (10 amp charger for about 4 hours, 2 amp setting for
another 10 hours), car starts up just fine the Monday morning.  

problem:  the airbag light now stays on for as much as 90 seconds after
startup where before it would go out very shortly (10-15 seconds?) after
startup.  

not-a-problem--or is it?:  the after-run cooling circuit seems to be
working at much lower temperatures than before.  (rarely did before, but
then temp never got too high)

please respond direct--i'm still on the list, but many many digests behind.
 thanks
