No fuse box, it uses electronic fuse breakers.

How about breaker box location and electrical prints ??
Been a volunteer Firefighter for 50+ years and going to need to put some EMS lights on my CT if I ever get one. RN1144*****

I bet you want to use lights which require 12V? That's not really available on the truck. There is a 48V accessory connection on the roof and in the vault I believe.

And it doesn't use breakers per se, the electrical system is controlled by the computer. If it sees something that it doesn't like, it will tend to turn off the circuit.

We'll have to wait and see what options become available.

Yes, 12v is the norm for LED lighting. There has got to be 12v circuits on the CT. All the trailer lighting is 12v. And usually a 12v supply to charge the 12v emergency braking battery on the trailer. I don’t want to have to do a Chop & Splice on an $80 vehicle. Hopefully someone will post a set of full electrical prints one day.

There is supposedly a 48V->12V inverter for the trailer and maybe 1 or two other things, but it's a 48V system.
And even on the 12V Model 3 and Model Y, 12V isn't the easiest thing to get ahold of.
I'm pretty sure that you will have to provide your own inverters. But they are relatively cheap on Amazon.
The Tesla light bar is supposedly going to pull power from the roof 48V panel and there's a switch for that in the UI.

But heck, you can plug all the on-site lighting into the truck.

As long as we are talking about the electrical system, it must have a 48V battery, right? Where is it and hopefulluy there is some better software to alert the owner it is time to replace the 48V battery. My M3 battery died without notice (that I could see). Fortunately it happend at home!

How about supplying 48V to 4 - 12v LEDs in series vs a parallel circuit? I’m no EE, but maybe that would work?

Yes, there is one, but it is a 4AH 48V lithium battery and not a classic car battery.
My Model 3 got a notification that it was time to change the battery. But that's a problem with classic car batteries, they can die really quickly.

Well, it would be a series circuit and they would probably need to be 4 identical devices, but even that may be problematic.

The 48V battery is likely to last a decade or more before needing to be replaced. I assume they are using a nice lithium battery instead of lead-acid.

Thanks Newwave1331 for posting the Tsportline video. Now I know where to get the power from. Got to get out my old college books and figure out what I need to build to drop it to 12v. OR if someone know of a 48v to 12v converter please post. I have to shop around!!!
Thanks, T

As I mentioned earlier " But they are relatively cheap on Amazon. "
