Hi folks. My truck started just fine today. I drove it to my wife's school to move some equipment for her. Got it loaded and tried to start. Got the "solenoid rattle" as if I had dead batteries. Put a charger on it, and it showed them as good. The "startup lights" (WTS, CEL, etc) on the dash come one for a few seconds, then flash off briefly, back on for a few seconds, etc. If I try to start it, the lights go basically out (again, like a dead battery). Battery connections look fine. Turned the switch to "run" so we could push it into a parking space. The whole time I was moving it, the dash lights were flickering intermittently. Any suggestions?
