I use the truck maybe once a week for a Home Depot run. Pretty much every time I have to jump start it. Brand new battery and alternator is good. Only thing I can think of is the anti-theft running the battery down. How can I disable it?

Hi,

The anti theft can't be disabled. Are you sure there isn't a light or something like that which could be causing the issue? Have you checked battery draw with everything off?

Take a look through this link. See if anything helps. Also, let me know if you have already performed a battery draw test. Also, let me know if you are comfortable using a multi or volt meter.

Let me know.
