I was curious about when I'm starting my Lightning, if the gauge needles are supposed to jump every time I start my truck, or just most of the time.:confused:

It may be from dirty cable ends or battery voltage drop during cranking. Look at those items or check voltage during start up with a helper.

I'm pretty sure i need a new battery. I'm guessing by what you told me that this could be the problem? Thanks

my gauges did the full sweep on start up, a new battery fixed it:tu:

+1. Mine did that for about 2 days then the battery crapped out completely. Kind of an inadvertent early warning system I guess....

My gauges just "wake up" as expected on start up.

The only time I've ever seen a full-sweep on the gauges is when I had the stock battery out for a period and installed an Optima Red-Top.

Just my experience.
