Just went out to start car and move it to show a buyer. '91 w/V6 Nothing. No interior lights, headlights or dash lights. Put charger on it, nothing. Put charger to dome light and it lights up and you can here the soloniods click on. Put charger negative to body frame and battery terminal still nothing. 12V power to junction box by air intake with volt meter. Cleaned those contacts.
Cleaned battery contacts, weren't bad. Battery has 12V.
Was running fine last week and 4 days ago.
Don't see any burnt or broken wires.

 

Fixed it. The red wire coming in through the bulkhead was loose/corroded. Wiggled it from under the dash and up came the dashlights, headlight and the thing started right up.
