2002 Chevy Suburban V8 Four Wheel Drive Automatic 174000 miles
When turning the ign key to on, dash lights up okay. When key is advanced to the start position all power shuts off to all systems. Everything goes dead. Battery is okay, shows 13-14V. After a few minutes voltage magically returns to the systems. This is intermittent. Is there a relay somewhere that controls all power to the systems and fusable busses? Electrical component of ign switch failure? The Chilton schematics show only a fusable link to the buss from the starter solenoid. Can this somehow partially fail? I though fusable links failed completely or not at all. Any advice?
