Thanks everyone for their help. This was the problem. Took off header and ran a new link. Fired right up. AutoZone carries them, about $4 each.

helrazr3 go under the car and check at the starter solenoid for 12 volts. and follow the small wire attatched to the positive bat cable and check the other end for 12 volts. do the headlights come on?

david-b I'm out here working right now... I have 12v everywhere at battery, at alternator, at voltage regulator... seems pretty good in the bay. Not sure what wires to check under the dash though. All fuses under there are good. Still nothing at all working.

FmrStrtracer Haynes manuals usually dont have wiring diagrams, you have to get the factory service manual printed by GM or Helms, check ebay.

On 70's GM cars, the fusable link is located by the starter solonoid on top of the starter, not by the battery.

helrazr3 the positive cable itself is very thick but you will also see a smaller wire along with it thats the one you want to look at

Ok I'll check that out. I know that wire from Positive to starter is a very thick and braided-looking wire. Like its wrapped with almost header wrap.

Positive cable goes to starter, then a wire with the fuseable link feeds off the main starter terminal to supply the rest of the car with power. If the fuseable link goes bad, no power to car. Test for power at starter.
do you have a chassis service manual(as used by the dealership), it will have complete wiring diagrams.
I have a Haynes book... will check in that. Would that link be inside the car or the engine bay? Or vaires?

helrazr3 sounds like you popped a fuseable link. trace the wires to the solenoid and see if you have a reading. if you follow them you should see a tag that says fuseable link

Ya electrical was a nightmare when I bought it. But once I had it figured out, haven't had any issues since until now.
Thanks for helping though! Really appreciate it. Anyone else got any ideas?
