I posted earlier but might be in the wrong forum. I changed my serpentine belt today now my gauges don't work. They act like they read backwards. I checked everything on belt as far as alignment. Any help please.

Id check the grounds.maybe disconnect the battery and see of that does it

I am charging the battery now it acted dead. Does putting these trucks in neutral and pushing them 2 feet mess something up.

I have no idea.you may have bumped a cable when working on it

I unhooked the battery and charged it. Now it works fine still wonder if pushing the truck does something to it .

The gauges wil act goofy like that if the battery is weak or at least that's been my experience
