Has your truck started since you put the battery in? If you have access to a voltmeter, can you check to make sure the battery is fully charged? Also have you tried jumping the truck yet since the new battery with any luck? And have you done the key dance to see if any codes appear on your display?. You should be able to do this by holding down the odometer reset button and putting your key into the on position (last position before it cranks). Let me know if you get a code that pops up. You may want to also check your fuse panel for any blown fuses.
2009 Ram 1500 5.7
Sluggish starting for the past several weeks. I replaced the original 4.5 year old battery and now it only clicks and the dash lights are going crazy. I tried tapping on the starter and shifting the transmission.
