I had an original 2018 battery which did show signs of aging not bad but it was on my mind. I tried to jump my tractor battery to see if that was the issue with my tractor (it was). My expedition was fine after the jump for a couple of days. After sitting for 2 days I start my car (starts easily) however I have a check engine light, my fuel gauge isn't reading anything (all the other display issues work fine) and my car is also saying the trailer battery is not charging and that my trailer turn signals are not working (no trailer was attached). I went ahead and replaced the car battery, I have checked the fuel pump fuse, I checked the trailer charging fuse they were fine (replaced them and it did nothing), so maybe a sensor, or could it actually be wiring underneath ??? as I had to drive into the field and there has been evidence of a mouse. I'm a do it yourself girl, so dumb it down please :) All thoughts appreciated Thanks
