This happened to me and others also with a recent software update. Press and hold gives only display choices, not button function choices. When I use the right scroll wheel it gives an error that the phone isn't connected. I never connect a phone, so whatever it's supposed to do now is of no use...

I'm finally back to working on the Roadster. I have the insulation, and I've replaced the caps on the first board of the three. I noticed that there is some kind of coating that was applied to the board at the factory after it was soldered. It is clear and is probably to prevent corrosion in the...

I'm back to the car, at least for now. When I left in early June I had charged the pack to 405V and left the plug out for preservation. After 6 months it's at 392V. Not much drop, as expected. Soon to work on the PEM.

Do you have a schematic or other info on the PEM? It would help. The other possibility is the HVAC unit. It uses a 400V compressor, so a short in that unit can also give the error. Since I don't have a way to fake the HVAC, I still plan on servicing the PEM, especially with many having problems...

Not normal. The precharge circuit is a relay and resistor that goes around the negative contactor. It's purpose is to slowly charge the large capacitors in the PEM. This avoids damage from high inrush currents. The precharge relay closes, and the V_ESS voltage ramps up as the capacitors are...

It looks like v_ess is the battery voltage after the contactors, and v_bat is at the battery. So there is either a resistance in the line to the pem, or a short somewhere after the contactors. I'm suspecting the insulators on the pem igbt's, but could be a shorted capacitor too. I'm getting the...

After doing a lot of very slow charging to recover my battery pack, I now get the BSM: V_ess too low during precharge error. It happens when trying to charge and when trying to drive. The battery is good, lowest brick is 3.97V highest is 4.00V. Pack voltage is 395V. But in the service screen the...

That's a lot of chargers! Sure get it done quick. What chargers did you use? Two per strip, small power strips?

Makes sense on the fuse. My 1.5 has fuses on all sheets. Wouldn't hurt to have both pins available to enable fuse checking. No bricks were at or near zero. Lowest voltages are above. I used 300mA to get the voltages up quickly to avoid further damage to the cells. They are all at around 3v now...

Figures. I didn't see that data sheet, so I used the more standard numbering. I wrote it on my board with a permanent marker too. Oooops. So going by the data sheet numbering I come up with... 24 is still 24 2, 12, 1, 10, 3, 22, 15, 23, 14 Have you figured out the difference between pins 10 and...

I have no clue yet. I can't get to the logs until I'm done with the battery pack. I do know that power was good the whole time, and it showed 241v on the screen when I looked.

You misunderstood. Those numbers are the pin numbers on the 24 pin BMB connector, not voltages. My post was in a different thread. How did your response get here?

I probed the pins and found the ones needed. Pin 24 is sheet negative. Pins for positive of each brick, in the order from 1 to 9 are: 3, 23, 1, 19, 5, 20, 6, 22, 4 The connector is a Molex 44428-2402. Mouser has plenty in stock. Note that the pins are spaced on 3mm centers, not 0.1"(2.54mm) so...

My roadster drained it's battery while I was away. I had it plugged in, but it stopped charging for some reason. Since it was plugged in it kept running the cooling system and killed the battery pack. It refused to charge, so I looked in the service menu. I saw VMin was under 2V, so I...

That's what I needed. The cabin temp number is valid in the service menu so I'm thinking it's probably the evaporator temp sensor. I'm hoping it's actually wiring or a connector. In case it's the sensor, is it wet? Also, did you get that from a wiring diagram? If so, where do I get one?

Anyone know where that sensor is? I would like to check it before calling the SC.

Ice in the brake lines can freeze, causing the pedal to be hard with no braking. Get your brakes flushed regularly.

Now 101 with my Roadster

My Roadster just arrived on Maui from Oregon. I added it to my State Farm insurance here with no problems.

My Roadster has arrived! #402 is now on Maui. I'm hoping to make it to the get together later this month.

I think that's the way it will be, though I don't need a real charge controller. With only 10A max coming in, by the time it got to the constant voltage level it would be plenty charged. Maybe a little too much, like 95%, so I wouldn't need PWM, just shut it off at the right voltage, then...

I'm 2 hours from the nearest charging of any kind, so I'm trying to work something out for right here. That means either the 120VAC charging and coming up with a way to turn it on and off to follow the sun and house battery SOC, or go direct to the Roadster battery. I can do it either way, but...

This gadget may be just what I need. Maybe. I have a second home in Hawaii. The property doesn't have electrical service available, so I'm "off the grid" with solar. I can set up the solar with a string of panels, but the current would be far lower than the Chademo can deliver. Up to about 10...

That's a good possibility. Another is that some water made it onto a PC board. This can cause oxidation, which can create an intermittent path with resistance across some of the traces. Another possibility is a strand of wire has broken off of a connector at the crimp and is sometimes contacting...

There is also one at Whole Foods on Hana Hwy. Be prepared to wait for the Leaf-ers! There are two pay chargers that are very reasonable at only 50 cents/hour. One is off Dairy Rd next to the Ohana Fuels. It is rarely used. The other is in Wailuku. I talked to them when they were first...

Your delivery person will probably be Jesse. He's from Maui. We talked story for quite a while when I picked up the Model S.

That's a good idea. I bounce between Hana and Oregon quite a bit. If I'm on that big pile of dirt when he's there, I'll look him up.

I was going to crash your Oahu party when I fly to Maui Sunday from Portland. Unfortunately I couldn't make it on time, and I would have had to leave pretty early to make the puddle jumper flight to Hana. Next time? Bill

Hi All, I'm Bill. I have owned a roadster for a few years now. It's presently on the mainland (Oregon) at my other home. I plan on bringing it to Maui. It should be a blast on the Hana Highway! I've had this property in Hana for just over two years. It's completely off the grid, so it will take...

I have decided to move my Roadster to Hana from Oregon when I get my new MX. Are there any other Roadster owners on island? I'm off the grid here, and at best will only be able to use my J1772 adapter. I have the HPC that I use in Oregon, but won't be able to use in Hana. I'm wondering if there...

I haven't looked into the main amp yet. I'm saving that for when I replace the stereo. I'm sure I'll dump the amp though. Bill

We all know the Alpine sounds awful. Super distortion. Well, it doesn't have to. There is some hope... When I got my car (used) the sub wasn't working. In fact, I didn't even know it had one until I was looking around under there to wire a two way radio. Sure enough, a tiny sub amp. Hmmmmm...

I bought a 1.5 in Portland recently. I live about 40 miles south of you in the Cascade foothills. I've put 2k miles on it, and I can safely say that if it was a Sport I wouldn't realize the slightly better performance very much. The 1.5 is already in need of more traction just to be able to use...

I'm 6'7" and the question I get is (you knew this would be it) "How do you get in that car?". That gets pretty old, almost as old as "How tall are you?". :P Two days ago I took a fun drive to a lake. They have an AeroVironment charger, so I hooked it up and went to lunch. When I got back out...

Today I completed the purchase of this Roadster... Of course, I took it for an extended spin to Eugene to see my daughter at UofO. I have to agree about the stereo (JVC). It sounds horrible!

Not a bad idea. I was looking at that bar in the one I am buying. I think I have some stainless I can use to make these. I'll check out seat mods. I've had to do them in the past. I'm not really into mods that can't be undone, like grinding away parts! An excellent idea. I don't need visors...

Thanks to all who replied here. I went to Portland to try out the dark blue Roadster. I'm happy to say that I fit (just barely), and so I'm buying it. Tomorrow I get started on the wiring for the charger. Thanks again, Bill

Good idea. I checked out the S soon after the Portland store opened, and I fit very well in there even without the glass top. So I'm reservation #11389. I also have a second home, and the Roadster would be perfect there when the S arrives here in a year. I watched the vid, and it looks like he...

I'd love to buy a Roadster, but I don't know about fitting into it. Anyone even close to my height want to comment? Bill
