Has anybody experienced there battery going dead if the var has not been driven for a couple of days. I also have a rear camera light displayed. Any thoughts where I should start? 
 

thank you

Bob, I'm sorry not to have answers for you but there is another place you can go.  Since you didn't indicate year or model I will give you two Facebook groups that have very high participation.  Your battery issue seems to come up frequently.  You might try LINCOLN NAUTILUS NATION and/or LINCOLN MKX NATION on Facebook.  Good luck on in your pursuit.

First have the battery tested USING A CCA test (not a voltage test). Determine if the battery is actually good (or just not capable of holding a charge).

 

If you actually have a parasitic load draw, the usual procedure is to run an isolation test. Connect an ammeter between positive cable and battery pos terminal. Parasitic draw will be about a 1/2 amp or greater. (The cars circuits are always drawing a small amount of current even when the car's shut off).

 

Start pulling each fuse in load center (fuse box), one-by-one and monitor when draw stops. That's your circuit. As each circuit usually serves several components, it becomes a simple process of disconnecting each device.

 

If nothing in the load center causing the draw, do the same with the Smart Junction Box (fuse box in cabin). 

 

If no circuit is responsible, suspect the regulator in the alternator.

Thank you, it turns out that there were 11 codes and the computer was over loaded,

once we cleared the computer the battery has been fine

 

thank you!!
