Separate names with a comma.
I'm NOT trying to start anything, but thought the question should be asked... With the recall by Hyundai of their Kona EVs for battery flaws, I...
Unless you need to have the charge finish more quickly, I've read that the "sweet spot" for charging is 240v at 24 to 32 amps. Higher wastes...
I get this one from time to time, nearly as often as the 104. No ill effects observed. I think it's just the APS power ramp not being quite what...
Just leave it plugged in. A 240v circuit is better than 120v, as it enables the car's A/C to actively cool the battery. Not needed now, but the...
A CAC of 139.63 is a bit better than my car's original battery now (136.9), after 11 years and 54k miles. So, the battery might have been...
If they're trying to hide things, I'd let it go. Not worth the risk.
There appear be other conditions that can cause the reset, too. In my case, the clock was fine for several days after the service before it got...
What software are you using as a viewer?
Puzzled. They are going to balance the battery? Normally the battery balances itself, and that occurs when the battery is full (above about 80%...
Yeah, that might get their attention, that we even exist. Doubt it, though. A "hack" that I discovered. Once you get an SMS message from your...
I went with a suction windshield mount. Works pretty well, does block the air or the view (Calif law - lower corner of the windshield is ok)....
I would just be happy (thrilled) if they would do a run of the Roadster-unique components, instead of buying perfectly good cars to be "harvested".
The voltage being reported is going to change depending on whether the car is awake or asleep. 13-ish when awake, 11.3-ish when asleep. The...
Odd that your 2.0 has a KD-NX5000. Most have the later version, the NXD505, but I presume they're similar. The 505, at least, does the...
In the second video, Pete opened the charge port door and plugged the car in while the logs were still downloading. I think normally (if the...
By "pretty good" I was referring to the battery. I think mine is about average for an original battery, maybe a tad below, based on the last time...
My car charges to about 160mi in standard mode, and the CAC is about 137. 169 miles, if it is that, is actually pretty good.
If the sheets are the same in both cars, both will have the same specs. Perhaps the numbers refer to 56kwh capacity, with 53khw usable?
I'm hoping we simply have newer packs...
Two? Where?
The 1.5 and 2.x ESS share a lot, but I don't believe they are interchangeable. The 12v system, which starts inside the ESS for example, is quite...
It's not going to hurt, I suppose, but I do not believe that storage mode changes the vampire drain aspect of things. Does anyone know...
I think what ML Auto is suggesting is to put a volt meter on the 12v battery (no charger), and see what it reads when the car is awake and asleep....
So, I think we're getting into a different topic than this thread, as the other errors suggest it's not simply a 12v battery-focused failure. Can...
Uh oh... #259 is not the 12v battery, it's referring to the main ESS. Same for #7. This is not a trivial one... No idea what 1522 is. #259...
Odd. As Jason says, this makes no sense. To your question, at least on my US model 2.0 car, there are two charging modes, and one discharge,...
I should close out this loose end... The next morning the battery voltage had risen to the full 13.76 float charge, though I should note that...
Nope. Just turned the wheels to the far right lock, and reached around the wheel. The rest followed Scotty's instructions here: Replacing the...
12v battery swap complete. Not sure I would call it "easy", rather I would call it annoying. But in the end I did not need to put the car up on...
Yeah, next time will do that for the battery, hopefully not for another 5+ years. The front and rear pieces on my car are the ones from the 2.5...
Thanks, both. Unfortunately, no, I didn't put any goop on either of the wires, but did wipe them with an alcohol wipe and all the stuff came...
Yes, that's the circuit. Do solder the connections if possible, or perhaps use a good "wire nut". Simply twisting them together isn't robust...
That makes some sense, though for the behavior I am seeing to be explained, the car must be resetting the switchpack (or something similar) when...
With the original fan assembly, the two + wires get connected together, as do the two - wires, just past the pair of connectors at the fan itself...
Also Think I need a new PEM Fan... Anything else to check? I just replaced the wiring between PEM and Fan, bypassing what Tesla had. The...
Right. But the 12v battery is held at the 13.77v float charge at all times, other than the 3 seconds immediately following the Unlock key fob...
Oh, very likely they are. Been thinking more about this... (yeah, dangerous). Logic follows: What is puzzling is how the software unlock (as...
Sure, but why is it pulled into action when the unlock button is pressed, even with the APS running? This is why I'm wondering if the current...
I had the 12v battery replaced by Tesla Service in 2015, and it's needing replacement again. Plan is to do it myself this time, in a few days....
Yeah, perhaps... Interesting that all this heartache with the 12v battery is just to save, what, 3 seconds delay between pushing the unlock...
Oops, change that. I wasn't watching the meter carefully enough. There's a spike to about 20 amps, then it drops back to 17-18 amps for as long...
Oh, no, it's worse than that. No door solenoids, just the unlock button on the key fob. Beep Beep and a couple of flashes of the headlights,...
Thanks for the pictures and references. What amazes me is the (tiny) size of the battery. 8-9 AH. That's all? I realized last night that I...
Hi Mark, that was exactly the next test I did. Interesting result. Still failed. In fact, the car doesn't even need to be locked. Doors open,...
Good point, but I wonder if they could deny the work, based on possible (or feigned) safety concerns. It does tap into the high voltage system,...
Probably. But if I had done that with the PEM Fan connector, I would have missed the failed connectors down by the blower, and not have really...
The 17 amp tug on the battery is coincident with the push of the unlock button on my key, not the door latch. One thought is that the car is...
Interesting idea, though I kind of like the trunk the way it is. I've been side tracked with other things, but will get back to the battery...
Hi Jason, Thanks for the pictures. Question: Are the connections to the battery really just the push-on F-type? Those can't be robust enough...
So now that the car is back on the road, the 12v battery seems to be done. I'm getting #428 alerts. Since I don't have the ability to do this at...
