Any mechanics out there?
2000 GMC Sierra 5.3 lost ALL power. No electrical power period. This was after driving in rainstorm. Battery is charged. Out of the blue it started once but would not run. Then no power again. Intermittently power would come back but when tried to start I heard a click and no power again. Cleaned all battery connections. Checked all fuses and fusible link. Very warm and sunny today. When I hooked up battery power is back and vehicle appears to be running normally. Alternator is putting out 14V. Is this the starter getting wet or on it's way out and grounding out the electrical system?
