Gourockian Posted May 12, 2021 Report Share Posted May 12, 2021 Hi, I've just bought a 2014 C-Max Energi and noticed it seems to be suffering from the dreaded battery drain issue. As the car was bought without warranty, I don't think I want to go back to the dealer about it, although I know him reasonably well. Before getting to my question, here is a summary of what I've done so far. I hooked up my multimeter between the negative cable (which I removed from it's grounding bolt) and an adjacent ground, to measure current draw. I've removed all the fuses, one by one, on the rear fuse panel and also at the passenger side - boy, that was fun. Whoever came up with that location must be a left handed part-time contortionist. I say left handed because it is difficult to work using your right hand. I ended up unclipping the panel and dropping it down to get better access to the fuses. Getting it back up was a trial and I eventually had to remove the glove box and that's when I saw that there are two stout plastic pegs which need to be correctly located in the steel back plate, before the panel can be clipped into position. Now to my problem .... I have tried for over an hour to remove the cover from the front fuse box (In the engine compartment) and watched a video which made it seem fairly easy. I don't why the securing latch has been placed at the back where there is limited space to work. So my question is .... has anyone else struggled to remove this cover and how did you finally manage to succeed? If and when I do get it off, my plan is to remove the latch arrangement and just leave the cover sitting in place for easy removal in future. The vehicle which this one replaced was a 14-year old Town & Country minivan and it's fuse cover was like that for 13 of those years, without causing any issues. Any advice would be greatly appreciated. Regards, Al Quote Link to comment Share on other sites More sharing options...
homestead Posted May 12, 2021 Report Share Posted May 12, 2021 There is a TSB for the battery drain. You can search this forum for that. Haven't had to open the fuse box under the hood so can't help you there. Are you sure your 12V battery is good? C-MaxA2 1 Quote Link to comment Share on other sites More sharing options...

I still did not manage to access the front fuse panel so I ended up taking the battery out, charging it directly then used my HF battery tester. It showed Weak at first then Bad so I've now replaced it. I thought getting the 12V battery out of my Prius was bad but it's a walk in the park compared to this setup. One of the hardest things was removing one of the pop-out studs that holds part of the plastic ductwork in place. It is dificult to get access to release and remove it. It would have been a lot simpler if Ford had used a regular stud and nut or bolt into the steel frame. Sorry about the rant but I'm hopeful the new battery will work out okay.

homestead Posted May 14, 2021 Report Share Posted May 14, 2021 (edited) Sounds good. So if you installed the battery the BMS needs to be reset. A dealer can do this or some OBD2 devices can do it. Even saw a manual DIY procedure once on this forum that may work to reset the battery age. Good Luck!
