Electrical problem
1985 Buick Lesabre Two Wheel Drive Automatic

My car is acting like the battery is dead, however the battery is fully charged. No sound whatsoever when turning the key. Interior, hazard, brake, or head lights do not come on. All fuses above the brake pedal are good. Car was running 100% up until last Saturday, parked it to go to work, came out to start it up and the interior lights came on when I got in, but nothing happened when I turned the key, and the interior lights did NOT come on when exiting the car. Connection to the battery was double checked, plus I cleaned all corrosion off of the battery posts and connectors. I hooked a voltmeter up to the battery and tried turning the car over, the reading remained steady and did not drop.

***UPDATE: Thank you for your help, hit my starter with a wrench a few times and she fired right up!

Hi, I'd check circuits to and from the ignition switch. The wiring info below, is all I could find for 85 lesabre. The S terminal at the switch, purple wire, carries voltage to starter solenoid, goes hot with key in the crank position. The red wires should be voltage to the switch. I forgot, there may be a fusible link coming off the bat terminal at starter solenoid, voltage for other systems, check voltage past fusible link, see if the wire is hot?
