Power Troubles 2004 F150 4.6

Asked by Feb 09, 2016 at 04:30 PM about the 2004 Ford F-150

Question type: Maintenance & Repair

My F150 will not keep a charge. If the truck sits for more than 10 hours it will not turn over, the keyless number code will not even unlock the door at times. The engine light has been on twice over the past 6 months, but goes away on it's own. I have checked the code before and it read "charging system."

Alternator is new, battery is new. Truck has 261,000 miles on it. Long story short, If I have to jump it off it takes 5-10 minutes for it to charge up to crank. I've been told I need to replace the battery cables, which I am not doubting what so ever. Another small problem I've noticed is my radio dash lights are very dim when my lights are not on. I wanted to reach out to see if anyone else had a suggestion as to what my issue could be? The truck has only had minor issues over the past 11 years I've had it: throttle body, A/C motor, rotors, etc... I've been blessed.

Sounds like you have a parasitic drain on the electrical system/battery. When you said the radio lights are dim, that could be the circuit that is the issue. You can view this video to see if you want to tackle the problem yourself....https://www.youtube.com/watch?v=KF1gijj03_0

I watched the first 30 seconds of that video and the truck will not even click/crank if it has sat for 10+ hours. I will continue to watch the rest, but I just wanted to get that out there. And to touch on the circuit, my cd player also reads error and constantly cycles through cds while I drive. Could all of this be the cause of one part going bad? The battery cables have to be replaced, there's no getting around that. Just wonder if I have let the truck go too long on those bad cables for it to cause another issue?
