Hi,
I have a 99 Express cargo van, 305 V-8, 112K miles.  This morning when I
was went out to go to work, it didn't start - dead battery was my
thought, so I had the neighbor jump me - started right up.  Let it idle
for about 1/2 hour
after I got to work.  I turned it off, then back on, and it started no
problem.  4 hours later, I get in to go back home and it went "tick
tick tick tick" with no turnover.  The ticking was in the dash, not at
the starter.  I thought battery again and went and got my charger.  Now
here's the part that might have screwed me - I left the battery hooked
up when I put the charger on it.  Now the gauges come on when I
put the key in and turn it to "On", but when I turn it to "Start",
everything goes dead and not a sound is heard from the motor.

Any thoughts?  Did I fry the computer with the charger?  Any suggestions
are welcome and appreciated!

Thanks,
Tom
