So it sat over the weekend after driving fine all week. I tried to start it Monday night and there was no response at all. When I tried to jump it, as soon as voltage was applied to the battery, the horn started blaring non-stop but still no function to anything else.
I noticed the battery fuse had blown, but as soon as I replaced it, it blew again.

Any suggestions?

Did you fix this? My guess is its a lead from the starter, alternator, or battery shorting with the chassis or a ground wire. Have you modified your wiring in any way?

Is this an alarm system problem?

Yet to be fixed. Wiring is all stock. There is no alarm. I'll check the leads you mentioned and get back

Checked the leads from alternator battery and starter, and all the connections and casing appear intact.
The starter isn't in circuit with the 80A fuse that keeps blowing so I don't thing its the issue but the alternator is but the connections and casing is all good.
What really confuses me is the horn. Could it be a bad relay somewhere?
Does anyone have a wiring diagram?

Are you the first and only owner of this car? If not, might a previous owner have installed an alarm system?

Unplug the alternator connector and the large wire attached to the fuse box to see whether the 80A stops blowing.

True, not the first owner, ill check more in depth for an alarm. As well as the alternator check
Thanks

Update: Ron you were right, found an alarm tucked behind the underdash fuse box.
Found that the plastic piece on the brake pedal that engages the light switch had broken off, replaced it and charged the battery. Everything works again.
I figure that it might have been the jump start that was blowing the battery fuse.
Thanks for all your input guys
