Lightning Jumper Connection Points (Photo)

Under the right front side cover panel. The panel has a raised silhouette of a set of jumper clamps molded into the top of the panel. Panel is easily removable using plastic turn-lock fasteners (unlike the Mach-E).

So this is where you'll connect your powersupply when doing module updates (not directly to the 12V battery).

Thanks for showing that again - I knew it was in the manual.

You note an interesting point - I would hope that if we have LONG updates like the poor ICE guys do that Ford will be better at maintaining the 12 volt battery since all they have to do is close the connectors. The truck doesn't have to be "Started" or driving like an ICE truck does to maintain the batter. This is a perfectly safe for them to do while it is sitting in a closed garage. Lets hope we don't have to resort to battery maintainers to get an update done. I do understand though this is reality for the ICE trucks today.

Well the problem there is that the Lightning has a bit of a lightweight 12V battery much like the Mach-E does. Nowhere near the capacity of say the one in the Powerboost. So if you try to do an IPC or IPMA module update that's done over CAN bus while directly connected to the FDRS laptop and it takes a long time and the truck is on "Accessory" mode and not actually completely "on" it's gonna eat that 12V in short order with all the cooling pumps and other things going on. That's why you need to have that powersupply connected and keeping everything at around 13.6V.

I guess if this were an ICE vehicle you could start the thing up and let it run while you did the updates, but most of the ones I've done on CAN bus on my MME are in Accessory only so your 12V battery is not being charged by the HVB during that process.

Strange that they would put the jump points inside the frunk. If the 12v is dead and there is no power to open the frunk, how do you access it? Can the frunk be opened mechanically if the battery is dead?

 

[Mike G]

Yes from inside the cab. Similar to a hood release on an ICE F-150.

Yes, there is a service release strap to manually open the frunk.

Can you get into the cab if the battery is dead?

Can you get into the cab if the battery is dead?

yes, with your key.

I thought the Lightning didn't have a mechanical key lock?

In that regard, it is like every other current late model F-150, in that it has a door lock in the driver's door (only) and a "key blade" integral to the key fob. Release the "key blade" from the fob and use it to unlock the driver's door. Use the Frunk emergency release pull tab (red strap) to open the Frunk. Grab the jumper cables, and Bob's yer uncle an Fanny's yer aunt!

Way can’t you go directly to the battery? It is easier to reach.

 

[Mike G]

Not supposed to. You connect to the jump points. The negative specifically needs a body ground, so the battery doesn't go into energy saver mode.

Per the note in a TSB:
NOTE: Verify that the negative cable of the charger is installed on a chassis or engine ground, and not the 12 volt battery negative terminal to prevent the battery saver mode from activating on the vehicle.
