Man I love threads like these. Keep on sharing and ignore the spectrum crowd.
I bought a Tesla Model S Gen 2 Charger - Now What?

How's your short-bus conversion coming along, if we're going to be characterizing each other?
Have to hit you over the head with it: This guy created two userids and is having a "conversation" with himself. Mods on some forums ban those who create multiple IDs for a number of reasons.
The dullard crowd wouldn't have noticed these antics, so resorts to name calling.
Feedback on practices and errors is important for someone who doesn't know what they are doing and is merely passing along the Cliff's Notes of what they read on Google and from OpenInverter and other sources.
There's a lot of reckless and negligent practices in these videos and "instructions"...as you noted, "ignore the spectrum crowd". They're just electrical engineers, lol.

I'm not going to get into a fight with you. You're absolutely right about safety practices and damn near all your advice, but like the other guy in his thread, you seem to live to shut down the obvious, non-harmful knowledge that people do need to know even if they haven't been veterans of the forum. There's utility in both. Not every post needs to be the first time a piece of good knowledge is shared. I'm lurking to learn before I fuck something up, and that means absorbing from everyone smarter than me, which is pretty much everyone here. But the holy than thou attitude risks turning off some folks into ignoring everything and just saying fuck it and doing something dumb.
Now, back to your regularly scheduled programming.

I don't overtly shut down any knowledge. Engineers are trained to challenge thinking, take the contrarian view, troubleshoot, solve problems. These kinds of places are where you might find them. Call it "spectrum", but you have no hesitancy driving over highway bridges...because it's a process that works. Places like Tesla and Spacex are brutal to work in...engineering-heavy successful companies have that culture and the ones that have group hugs don't get very far.
If I do shut down knowledge, you are welcome to call me out. I try to clarify, add, answer or stimulate conversation. Threads are kinda dead unless you shake them up a bit. Eating a bag of popcorn and reading a forum is good, but you're worthless because it's about everybody participating, not merely showing up. Your problem is not yours, it's the next guy's, and the next gal's after that. Leave a thread sloppy and you'll mess up everybody that follows. Until you get that, you will never understand Brian or myself or a few others here in the "spectrum" club. This is a reference resource, not Ask Heloise.
I try to correct or highlight errors and problems, especially with this Youtube generation, one here of whom just ignores what I see as serious issues, and he just carries on. His choice. He'll be paying for the lawyers.
Another Youtuber also ignored two people's inputs, I explained, they seem to have understood.
You put a video up in the context of being an expert, everything you do had better be exemplary of being safe and utilizing best practices, particularly when it comes to high voltage. Otherwise, you're just a software bit-flipper with a camera, pretending to do hardware, baiting the next guy to become a pile of graphite on his garage floor.
There is a distinct difference between teaching and telling. In teaching, you learn, teach, get opinions and feedback, learn more, modify, teach. In telling, you say it once, move on. Or tell it several times, not changing what should have been corrected. Or you create an alter ego to bait the tell because few are participating. Nobody knows where you are going or what you are doing when you throw a 2x4 foot sheet of plywood on the ground and start moving modules around like a three year old...purpose doesn't matter when you're telling.
This thread is very useful, but firing up a high powered charger full bore with no cooling, for example, is reckless, imo. Best case, you kill a $350 charger's output devices.
Unlike kids making slime at home, stuff we do here can be lethal or can cause a lot of damage. Open terminal 390VDC on a wood-floored dining room plus lithium batterie...all outside a fireproof, arcflash proof, case? Wow.
There's no preface of "Don't do as I say or do as I do...just watch the software and 5V part."
Even there, electronics are being handled on a plastic Harbor Freight Tarp. Now do that with your $1500 Canbus GUI controller's board, fry it with static electricity because you saw stuff done on the DIY Electric Car guy's video on a plastic tarp...gunna shrug it off or get pissed off because he was an expert? He must've put that tarp down for electrocution safety, right? (I hope not...)
Anyway, if you see something not right or that can be done better, or see someone scratching their head or looking for ideas, put the popcorn down, steal a baby wipe and clean the butter off your fingers, and type a paragraph in response with your opinions, experiences, knowledge, resources...that's what makes this a forum and not Ann Landers.

I don't disagree with anything you said. Reading back over the thread, I think I got tired of Greg's posts which were merely mocking and conflated that with some other posts of yours in other threads. Either way I apologize. Being late on a Friday night didn't help. 
I do find stuff like the exploration of the charger parameters helpful. I haven't seen that info anywhere else yet.

Greg i have a task for you. Can you make your charger run on full power 240Vac and inspect what you get returned in spot values in hwaclim value.
My charger is vidently limited to 13.3A per phase and i can only get 8.8kW on the whole out of it. I would like to see others write their limits here too.
tnx

Are you running coolant through it? Greg wasn't, so upping the power in his dining room may toast/limit the charger.
I have it mounted in my car, coolant, CAN bus, 12V and whatnot...

Has anyone bought a board from EVbmw lately. There seems to be other parts missing from the board now.
