Parasitic Drain

Asked by D. Brad Nov 17, 2018 at 12:01 PM about the 2008 Ford F-150 FX2 Sport SuperCrew LB

Question type: Maintenance & Repair

Positive connector attaching to the positive post
on my battery was corroded to the point of no
return on my '08 F150.  They do not sell just this
connector at dealership, "Have to purchase a
whole new wiring harness".  So, I cut the old one
out, and daisy-chain the 3 wires/cables leading
to the post.  If I do not drive the truck for a day or
2, it's dead.  Checked battery, and it is fine......any
ideas???
