Hey all

My first big burnout. I inadvertently left the key in position one for several hours--the battery was low when I discovered I had done that, so I shut the key off, put the charger on and a couple hours later attempted to start--no go. No tack jumping. I switched with known good voltage amplifier (on left fender well) to no avail. All idiot lights illuminate, just no start, although it turns over fine (battery good). What gives? Did I fry the computer? What other models' computer can I use--the salvage yard has no 88 760Ts. Or is there something else I can look at?
