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?

TMS,

What does a voltmeter say? Have someone true starting the truck while you watch the voltmeter reading.. It really does sound like you have a pair of dead batteries. I don't particularly trust what a charger says about the batteries' health. Or pull both batteries and take them over to a battery shop and have them checked out.

Thanks. I am actually wondering that myself. I just looked it up. I bought the batteries in May 2016. They SAY 6 year, but we all know that's rarely the case. Hopefully I can put a meter on it tomorrow.

Battery connections "seem" ok has made a monkey of me, on several occasions. Lol

I would start there, remove and look, especially if it's been a long time since they were cleaned. Make sure the cables are still tight in the cable ends also, no major corrosion.

From what you are describing, it sounds like a loose connection, check ALL the connections, batteries, starter solenoid, starter, everything.

I'm with the others, it has to be a connection somewhere, check all connections and grounds.

Pretty sure it's simply dead battery(ies). I tried to jump it off a Jeep 4.0, but it just wasn't enough juice. It DID at least engage the flywheel and try to start, just didn't generate enough RPM to do it. Got the batteries out and have one on the charger now. I'll be disappointed if my 6 year batteries have only made 3.5, but I should be able to get about 35% of my money back. These are Interstate Megatrons. If I decide to go with something else, what do you guys like? I will double check all connections for cleanliness and tightness when I reinstall.
