Customer Question

I have a 2014 Explorer which I tow behind my motor home. At the end of a 6 or 7 hour day on the road, the battery on the Explorer has drained and I need to jump start it. Why does this happen?
JA: Will the headlights turn on? Is the battery fully charged?
Customer: Today, the battery still had some power because when i OPEN THE DOOR, THE DASH WILL LIGHT UP BUT THERE WAS NOT ENOUGH JUICE TO START THE CAR
JA: Are you fixing your Explorer yourself? What have you tried so far?
Customer: About two years ago I ran a 12 volt wire from the RV to the battery of the car through the lighting harness. That seemed to work for about 18 months. I could go 10 hours at a time and the car would start with no problem
JA: Anything else you want the mechanic to know before I connect you?
Customer: That is all I can think of.

I have connected a 12 volt line through the wiring harness directly to the battery
Expert:  cloe0626 replied 3 months ago.

have you checked to make sure the 12 volt line is getting power too i see where you said you installed it a couple of years ago

Customer: replied 3 months ago.
checked that, the 12 volt is live in the wiring harness and there is good connectivity from wiring connection to the car battery
