oh boy. car wont crank after shorting alternator wire

Ok new at this forum thing so here i go.

So i had the red single wire off the alternator disconnected to free up room while i had the valve covers off. when i went to put the wire back on, it touched the side of the alternator and it sparked... now when i turn the key, nothing happens. no clicks no starter. what did i fry?
- this is an 81 elcamino , no ecm. carbed 350.
- also the buzzer comes on when i put the key in the ignition but no instrument cluster power. interior lights still come on.


i believe i traced the wire all the way back to the firewall where it goes to the fuse block
- all fuses visually look ok.
could this be a fusible link?

thank you all in advance!

No s*@t!
gotta learn the hard way. Is the fusible link a type of permanent slo blow a few inches after the starter?
is this type of thing an auto parts item or do i rig up a 60amp fuse of some type in its place?

Thanks , gonna give it a whirl tomorrow morning!

Found it.
turns out one of the wires going to the "s" post on the starter was crapped up, cracking and missing insulation from all the heat from the headers.
when i arced the alternator i suppose it was the straw that broke the camels back. when i touched the wire , it disintegrated. Now that i wired up new leads the power windows roll up faster and headlights seem brighter too.
- also, you got me thinking of mega fuses now. i gave it a look, totally gonna wire up a 250 - 300 amp main fuse on the positive terminal at the battery. cheap insurance.
