Agree.
Likely when torqued something is loosing contact (open circuit) or shorting out.
First things to do with a new-to-you vehicle: fully charge the battery and have it load tested. Clean the battery posts and both ends of the main cables. Locate and clean all the grounds you can find--strip to bare metal and treat with an anti-corrosion agent, then make the connections TIGHT. Pull each and every fuse and check them with a meter, clean up the contacts if they are corroded. Change ALL of the fluids, ALL new hoses, new belt. Check the fan clutch and all belt driven accessories and idler pulleys for wobble or roughness when turning. Inspect the weep hole on the WP, replace if weeping.
Wheels on the ground have a friend slowly move the steering wheel back and forth while you observe the suspension for odd movements. Jack one front wheel off the ground so it turns freely. Grab the tire at 6 and 12 and see if it wobbles--if it does you need ball joints. Grab the tire at 3 and 9 and see if it wobbles--if it does you need unit bearings.
Check all of the u-joints--one each side in the front axle, two in both the front and rear drive shafts.
Check the brakes, front and rear. Flush the brake fluid--only good for about 3 years as it is hygroscopic--it pulls moisture from the surrounding air and contaminates the fluid. Inspect the flexible brake lines.
Install new wipers and clean the glass inside and out.
