HI, Does anyone have any simple instructions as to how to remover the plastic covers over the main battery. I took a quick look today and removed some of the torx screws but it still does not look easy to remove to get full access to the battery and wiring. Also on the 7 post busbar there is a spare terminal number 4 that i believe is for the inverter when fitted. Is this a suitable place to attach a connection to power external 12v devices ?

Remove the rear footwell panels (assuming you don't have carpet), they just pop out; then at the forward edge of the plastics (where it meets the metal floor) you'll find two covers per plastic panel that pop up, remove the 10mm nut under each one.

Flip the rear seat bottom upwards and remove the T25s that hold the front and rear halves of the plastic covers together. Additionally, there is one T25 that holds the left and right forward plastic pieces together in the middle.

After this, remove the silver T50(or 47?)s that hold the rearward panels in place.

If you have a commercial (N1), you'll need to unbolt the rear seat bolts to gain access to the rearward T50s as they are under the upright portion of the seat.

The empty post on the busbar should be fine to power other devices (I use 2 empty posts for that purpose), however, make sure you place the appropriate fuse on the busbar, it uses a specific ZCASE fuse

Thanks very much for your quick reply, I have a trialmaster not commercial so hopefully the last bit does not apply. Rather fiddly in my opinion compared to other vehicles I can see that plastic cover getting cut or not even put back at all as the vehicle gets older.

I want to take a feed from the 4th terminal to power something that will pull around 40 Amps at 12v, there is a 60amp fuse already in that location I undersand so will probably suffice.

Also is there a good earth point in that area other than the negative terminal of the battery ?

There is where the negative battery cable goes, as well on the opposite side you will find a 13mm nut where the auxiliary battery earth is normally (if you have that option, if not, it's wide open)

Ok any advice on the T50’s that hold the rear plastic covers in? The crossbar is right in the way. I was able to get 3 of the 4 bolts out using a short T50 1/4 drive but the last one is under a main crossmember?l and tight as hell? Not much room. Curious if I am missing something on this? I think I can get the last one out but the bolts are really tight for what they are and what they do. It appears they also have loctite on them?

The panels also look pretty fit into the current locations so maybe I am missing something? Any help (pictures) would be awesome and thanks!

I unbolted the frame supporting the seats and lifted it up a few inches. Something like 16 bolts, the plastic covers need removing at either end to get to all of them. It took a while.

Having done that, I trimmed away the majority of the plastic cover over the battery and busbar to allow easy access in future.

Use a T50 Allen key. It’s very tight and yes all bolts have blue loctite on them.

You mind sharing some pictures? I think I am going to do something similar - remove the excess plastic. I like the idea of the “catch tray” at the back of the seats I am going to likely leave that in, but the rest of the plastic under the seat seems pretty useless.

A stubby T50 hex bit fits under the crossbar.
Slide a gearwrench style ratcheting ring spanner over the T50 hex bit then place it on the bolt and away you go. Use the wrench to drive the bit. I don't recall the wrench size needed, 8mm maybe.

Yep that is essential. Hopefully someone will come up with an after market replacement for this crazy setup that provides a barrier but has an easy lift up panel to get access.

I tried 1/4 drive impacts (1/4 drive and 1/4 wrench) that I had and got all but one of the bolts out. I ordered the Gearwrench stubby TORX in hopes that it will work, but honestly - this is just stupid. There is no logical reason to have such a large bolt to secure the plastic panels and then put it in a place you can’t really get the appropriate tool into.

No dust covers on the main fuse box, covers in the AUX fuse box, covers on the Littlefuse boxes and then plastic junk over the main boxes you might need to get to in an emergency and you can’get get a wrench in to remove them?

Sorry for the rant and maybe I will find others, but the plastic panels you can’t remove to quickly and easily get to the hear of the electrical system on this vehicle is just maddening.

Agreed. The bolts are oversized. It's like the designer of that section has never heard of panel washers.
I removed the under-seat trim two weeks after I took delivery in July 2023 and it hasn't gone back in. I will reinstall it one day after I make some mods to improve access to the electrical components and both batteries.
Be aware that once you get the bolts out it's still a PITA to remove the trim sections. Lifting the rear seat out would make it easier. I didn't do that and I had to get emotional with the sides to flex then pull them out. Way harder than it should be. Imagine trying to do a roadside battery swap with the trim installed 🤬

The idea of removing rear seats to remove a panel that requires critical access is just silly. We are not talking about an ECU - we are talking about all of the major fuses and wiring on a vehicle that was designed to have modifications done to it.

I get the “drip” ideas on the back of the seat and then between the split in bottoms, but this could have been done with 10MM bolts and large washers.

I also tried to pull the side trim on the seat brackets on the side and while the clips pooped out - the Philips plastics clips were a joke - no threads - just the push in type.

Again - love the vehicle, but some of these issues are a comical. Magna should be ashamed of this type of design execution.

Yes its much harder than it needs to be, but doable. I suspect the oversized rear bolts may be because they could be used for something else that needs that size in another/future? version of the car.

In the next few weeks I have to remove the panels again to fit a fused Anderson plug pigtail, so I can connect my solar regulator/charger without opening the bonnet. I'll take some pics to put around @anands words as it strikes me it would be a useful how-to addition to the manual.
Cheers
Steve
