    Any reason not to leave roadster plugged into 120v outlet?

    If you have an outlet that is the only thing on its circuit, it's easy to convert it to 240. You won't be able to increase the amperage, though. But converting a 5-15R or 5-20R to a 6-15R or 6-20R just requires a minor modification to the wiring in your breaker panel and a new two-pole...

    Caution - Annual Service - Car power-down - GPS issue

    That would be the best possible outcome, but I don't think open sourcing IP is consistent with Tesla's culture or history (despite the mostly meaningless "opening of patents" stunt several years back).

    Caution - Annual Service - Car power-down - GPS issue

    I'm under the impression that the firmware for our cars is officially abandonware at this point.

    How I upgraded from NEMA 5-15 to NEMA 6-20 for $66

    What Rocky_H said. NEMA 6 receptacles have no Neutral, so you need three conductors; Hot, Hot, and Ground. All the OP did was re-purpose the old Neutral wire from the original NEMA 5 receptacle (which uses Hot, Neutral, and Ground) and use it for the other Hot, so he now has the needed Hot...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    I've had a Google Fi data-only SIM card working in my OVMS since I installed it a few years ago. I just got a new 4G modem yesterday (Medlock has them in stock) but I haven't installed it yet. My APN is set to "h2g2"

    Service / Delivery Center - Alhambra, CA (1200 W Main St)

    When I was there last month there wasn't really a showroom and there was still a lot of black tarp up. Seems like they might have put the remodel on hold.

    Service / Delivery Center - Alhambra, CA (1200 W Main St)

    I live relatively close to the Alhambra SC but they always schedule me at Burbank for some reason. I was able to get the latest service appointment moved to Alhambra, but I had to do it by text message request, and now the appointment doesn't say which SC, it just says "Service Center", as if...

    50amp vs 30amp 240v Outlet

    I second (third? fourth?) the suggestion to put in a 14-50 or 6-50 receptacle (as has been pointed out, the 6-50 omits the unnecessary Neutral conductor, saving you money on wire) and put it on a 40 amp breaker. Use thicker wire than you need so that if you ever upgrade the main panel, you can...

    Non-Tesla Dealers marking up car prices

    The correct answer when a dealer asks for a "Market Adjustment" is to walk out. If everyone did that, they would stop doing it. I think the bigger problem with dealers and EVs is that dealers don't want to sell EVs because they don't support their revenue model, which is based largely on their...

    Security PIN not available

    Those are balancing weights, the TPMS sensors are inside the wheel so they're not visible.

    backslash \ button missing?

    And people who realize they have no defensible point like to cliam "that's not what I meant".

    backslash \ button missing?

    Well, you weren't very clear about it then. You made some comments about secure passwords being possible with the limited character set when the issue is that the car's virtual keyboard has a clear deficiency that you seem to reject. Yes, of course people could work around the problem by...

    Today's Roadster Orphan

    If a battery is being recovered, that process should be done in isolation and never unsupervised. I imagine Pete, of all people, appreciates this fact. But he has said that this fire started in an electrical panel. I'm very curious how that happened without immediately tripping a breaker and...
  14. rudholm

    backslash \ button missing?

    Facepalm indeed. The assertion that one should change one's passwords to accommodate the car's lack of the basic set of printable 7-bit ASCII characters is absurd.

    Roadster loss

    Well this is a disaster. I'm beside myself. How could this happen, again?

    Saying Hello From L.A.

    I find Southern California Edison's Time-of-Use price plans to be ideal. With the one I'm on, the cheapest rate is 12 cents per kWh between 10pm and 8am, so that's when I charge the cars.

    Saying Hello From L.A.

    I'm not sure if Javier does sound dampening. If he doesn't, I would go with Carl. There's some stuff I need him to do on my car, maybe we can get him to come to LA.
  20. rudholm

    Saying Hello From L.A.

    There's really nothing to do to the battery after sitting. As long as it was plugged in, it'll maintain its health on its own. If you have a 240V electric clothes dryer outlet in or near your garage, that's a perfectly suitable power source for 240V charging (that's what I used until I got my...

    Service in socal (orange county)

    Given that there are only about three shops in the whole of the US that service these cars, you're actually kind of fortunate to have Executive Motorwerkz right up the 405 in Lawndale. Otherwise, the simple answer to your question is "no".

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    I guess I should have included this: Firmware: 3.2.016-240-g001b3182-dirty/ota_1/main (build idf v3.3.4-845-gd59ed8bba-dirty Jun 28 2021 09:06:51) I do have console but I don't have an SD card installed.

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    OK, I just tested this on my 2.0 (0693) and it did the job, but it required me to swipe the virtual charging slider twice. After the first swipe, the charging plug icon disappeared like before, but this time, it came back a moment later with the slider back in the left position and the car woke...

    Caution - Annual Service - Car power-down - GPS issue

    I like how this unassuming little serial cable, purpose-built to solve a single problem, is wandering the globe fixing every Roadster it touches. I feel like it should write a book about its travels when it gets home.

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    That makes sense. And I seem to recall Mark saying that it's not possible to manage charge scheduling via OVMS.

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    I'm wondering if anyone else has this problem. When the car is plugged in, but not charging, if I slide the "Slide to begin charging" thing on the icon of the charging connector on the Battery page in OVMS, it doesn't start charging, it just goes into the "Charging -- Prepare" state (according...

    Registration Mandatory?

    California non-operation registrations don't expire, you pay the non-op fee once and it remains in non-op status until you change it, you don't pay annually like you do with an operating vehicle.

    What have you done to your Roadster today (or lately)...

    Does the screen collide with the windshield wiper stalk when it extends/retracts?

    All these refinished wheels look great. I'm starting to wonder what color/finish would look good with Glacier Blue.

    Wrong Power declaration by TESLA leads to re-payable Tax??!!

    Why would they change the published specs for a car they barely care about and haven't made in nearly a decade? And knowing Tesla, I find it very hard to believe that they would send any such notification to the Swiss (or any) authorities even if they did. Something doesn't seem right here.

    Not what you want to see on a Saturday night...

    The saga ended last week. Medlock & Sons replaced every rivet connection in my car's battery. While it was up there, he also replaced some other things that needed it; tie rods, some PEM connectors, the clockspring... Replaced the amplifier and subwoofer as well and added some sound...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    OK, good to know that I'm not just overlooking this functionality at least. The reason I ask is because my car is throwing a Battery Sheet Error, which, when active, makes the car un-driveable. But sometimes the error goes away. I'd like to know when the error goes away so I can charge the...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    I get those, too, but how do you know when an error goes away? Is there a way to poll the car to see which errors would be displayed, if any, when you press the exclamation point icon on the VDS?
  35. rudholm

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    This seems like it should be simple, but I can't figure out how to see current error messages through OVMS. I have some errors that are intermittent and it would be helpful if I could check error status without going to the car to see them. I've searched around and haven't been able to figure...

    Finally! A modern stereo for single-DIN Roadsters

    I'm 6'2" and have a long torso, so I didn't have a good view of the HVAC controls to begin with. It was relatively inexpensive and easy compared to trying to convert to a 2.5 dashboard. It doesn't look painfully non-OEM because the face of the screen doesn't protrude forward of the dashboard.

    Finally! A modern stereo for single-DIN Roadsters

    Before I got the new head unit, I used one of these: Spigen Kuel Stealth Car Mount It was $18 on Amazon. I stuck it between the center two HVAC vent humps on the dashboard, as far forward as possible. It worked very well. It's landscape-only, if that's an issue.

    Caution - Annual Service - Car power-down - GPS issue

    ttyS1 is the standard name for the second serial port's device node in Unix/Linux. ttyS0 would be the first serial port. "tty" is a historical designation meaning teletype/teletypewriter, "S0" means the zeroth Serial device. Anyway, it just means these data are arriving via a serial port...

    Model 3 Range decreased again...

    I lost 10% of my estimated range at 6 months of age and about 6,000 miles. The car is now 10 months old and has 9,850 miles and is showing an estimated 271 miles of range at 100% and 135 miles at 50% (using the charging slider in the app). This is a M3P. My Roadster has lost less estimated...

    backslash \ button missing?

    This is still an issue. I was trying to log in to a website the other day and discovered that there are no \ or | (pipe) characters. Seems the special and punctuation characters set is somewhat incomplete. This is in a Model 3 running 2020.4.1. I considered finding the character on a web...

    Today's Roadster Orphan

    I was a little surprised that he didn't know what the "R80" meant. Or maybe he did and he was just trolling to drive up comments on the YouTube post. It's pretty easily googled. Or, a few minutes here would yield the answer.

    Today's Roadster Orphan

    Indeed, that price strikes me as "aspirational", especially without the CAC, SoH, or even a "charge to" range mentioned.

    Not what you want to see on a Saturday night...

    I suspect that the degradation problem with the original 3.0 pack was a big part of why they pulled it from the market. I have to assume that all the testing, validation, and firmware work they're doing on the new pack means it's a redesigned unit, which presumably addresses the degradation...
  44. rudholm

    Not what you want to see on a Saturday night...

    I agree. I got the impression that it was a new battery design and not just more of the old 3.0 battery. Since I was caught completely by surprise by this news, I didn't have questions ready. I'll ask for more details: What's the capacity/range of this new battery? What's the warranty period...

    Not what you want to see on a Saturday night...

    I spoke to Matthew at Tesla today. I was impressed with how knowledgeable he was about Roadsters. He told me that Tesla will re-introduce the 3.0 battery at the same 29k price point and that it's currently in testing and firmware updating. He said it could go back into production as early as...

    Any problem with two HPWC Power Sharing to charge Roadster with CAN Sr?

    I have two Wall Chargers set to share 80A (on a 100A circuit). When I come home after a day or commuting with the 3, it charges at its maximum of 48A. If I come home after a day of commuting with the Roadster, it charges at its maximum of 70A. If they both need charging, they each get offered...

    yup yup. If you're in socal and have a Roadster (or BMW) Javier @ExecMotorwerkz is your guy. He gets to know his customers and their cars. No nonsense, no BS, and no gratuitous upselling. He has fair pricing, and keeps his agreements and schedule. He's one of those merchants who figured out...

    Looking to buy a 12V/15V Charging Cord

    I third Henry's and shrink's suggestion. When I only had the Roadster, I charged it with the Roadster UMC off a disused NEMA 14-30 dryer outlet (30A outlet, from which the UMC made 23A available to the Roadster). But when I added a Model 3 to the garage, I needed another charger. I believe...

    Holding on to your Roadster. . .

    Keep the old PEM. Send it to someone who can fix it. And if it makes sense, have them fix it, and then sell it.

    Holding on to your Roadster. . .

    I'm curious how much they quoted you for that PEM replacement.
