Gauge sweep?
I'm not talking about the dealer test sweep either. Today when I started up the truck and left work, it cranked a bit slower than normal and all the gauges swept to full max, then back to normal operating level. Ideas? Battery is original so I am sure that is about due for replacement. Just want to make sure I'm not overlooking something else. Truck ran find the entire way home. Thanks
Thanks guys, will get it today, unfortunately we are getting hit by a huge snowstorm, should be fun to change the battery out in the middle of the parking lot! Any recommendations on battery size(cca's?)
