Just bought the truck 2 weeks later the battery light goes on and off intermittently. The battery checked out good replace the alternator that's good, but that likes teams to just keep going on and off.

Hello,

This sounds like you could have a loose wire or a damaged electrical connector that is causing the light to come on intermittently. In the diagrams down below I have included the wiring diagrams for the instrument panel and the charging circuit for your vehicle and a guide for finding intermittent conditions in an automotive electrical circuit. You will need to use a Digital Multi-meter [DMM] to go through these guides, so here is a link below with instructions on how to use one, if needed:

Please go through these guides and get back to us with what you are able to find out. We can go from there, if needed

Thanks,
Alex
