The gauges are all cycling to full upon starting the engine and then go back to normal settings?????? Is this an electrical issue??

Thanks

 

Most likely, your battery is on its way out. I ran my truck for almost a year w/ the guages sweeping before I replaced the battery ... my alternator failed shortly there after. My suggestion is you replace your battery sooner rather than later.

 

Run over to Autozone and get the battery and charging system tested. It's a free service.

 

Yep, it's usually an indication that the battery is weak. Takes a lot of juice for these trucks.
