    PEM, motor gets too hot -- fans failed

    The 010 is bigger. If you buy a 009-A70-74D from Ebay or Amazon, you will have to splice on the Tesla connector directly to the motor leads, which bypasses the speed resistor that is mounted on it.

    Hardtops and other clear carbon fiber parts now in production

    Just my 2 cents on the mudflaps-- I made plain flat carbon ones for one of my roadsters and they do drag on the ground quite a bit on lot/driveway aprons (very loudly I might add). My flat ones will bend and just wear on the bottom, but if you make them molded like the original units they will...

    SF Bay HPWC

    Sounds like your pack is failing and is way out of balance. Check the min and max voltage readings in the service menu. Charging stops when one brick reaches just over 4.1V (standard mode).

    TPMS sensor battery failed

    I doubt you will find someone to program sensors that you buy elsewhere. All the brands of sensors have their own programming tool. The universal sensors have to be configured first to the car type, and then only some of them can be reprogrammed with a new ID. There was someone on EBay that...

    TPMS sensor battery failed

    Some universal sensors are only adapable to the type of vehicle, the actual programmable ones you can set the ID, so you can swap them without a relearn. You can order them online, but you need that fouth ID#. See if you can find someone else local. Tesla will just sell you new sensors and then...

    TPMS sensor battery failed

    The ID number is on the unit itself, but sometimes it can still be read with a TPMS tester. The signal is just not strong enough to be read by the car when the battery gets weak. A shop that sells the programable sensors can do the work. If you write down the ID numbers and locations, you can...

    Rear tie rod ends--Lotus or custom?

    No, it is a direct replacement. The Lotus had an upgrade that included the spherical rods and a cross brace to put the attaching bolt in double shear. The standard Lotus design used a regular ball joint type tie rod (with a 4 inch long stud to attach it) and was prone to failure during track...

    3.0 Battery Longevity

    Say on the screen with the min and max voltages, then look at the min when you floor it and get the power loss. That should provide some more info.

    Roadster 1.5 clicking noise from the front

    That happens when your rotors are warped. Or in your case with new rotors they are probably not seated correctly on the hub. Otherwise you would just get a rattle over bumps from the loose pads.

    A long hex with a ball end works. Just make sure you protect the seat where it rubs.

    3.0 Battery Longevity

    That's pretty much balanced. It stops right around .03v difference between min and max.

    3.0 Battery Longevity

    You need to show the max and min voltages to show how balanced your pack is. As long as you don't have all ones except one zero you should be OK. One zero would indicate a low brick.

    Today's Roadster Orphan

    Thats only a loss of $4750.00 per mile driven. Plus 14 months interest on their money. Not a very wise flip.

    That definitely sounds like something with the wheels. Could be a nail or screw in a tire. There is no speedometer cable.

    HVAC: Low Current Pump Failure

    Drive it easy and you shouldn't have a problem. It takes a while to heat up the battery. There is not a lot of coolant volume outside of the ESS, so there is really minimal cooling taking place until the A/C kicks on for the cooldown cycle. The main purpose is to keep all the cellls at the same...

    Help! Battery cooling pump will not turn off.

    There are a lot of variables for the pressure reading, but you should mention that there is a sight glass on the drier so that they fill it correctly. They might not see a lot of Roadsters. A total evac and recharge is not the best solution.

    Help! Battery cooling pump will not turn off.

    Based on your pressure reading with the A/C on, you are low on refrigerant. It should read around 13-15 bar.

    Help! Battery cooling pump will not turn off.

    A couple a questions that need to be answered first: Does your A/C work? Does the A/C come on when charging? What is the battery temp? 30c and above the pump will stay on. Is the coolant level full? I cant see the level in your pic.

    Turning angle disabeling regen?

    The regen turns off when some rear wheel slippage occurs. So if you are going around a sharp corner fast while braking, the inside wheel might start to lock up and activate the ABS and disable regen. If you are not braking, I dont think the regen will turn off unless you hit some loose surface...

    Dead Roaster - switchpack?

    The multifunction relay is not the Tesla switchpack module. I have seen it called a switchpack in lotus applications, but it is just a mechanical relay box. The Tesla switchpack is digital control module. The Roadster uses both.

    Can anyone talk me into spending this much on me rotors?

    The EBC rotors rust a lot less than the stock ones. I only see slight rust if they get splashed directly with water. But the slots are the reason different rotors help in the initial breaking. The OEM drilled rotors just dont have a path for the contaminants to escape.

    HVAC not cooling!

    Your pressure seems a little high. Are the fans working at full speed? They start on low and then kick on high around 15bar. If they are fine check the condensor for road debris. Look through the grill on the bumper at the bottom of the condensor. You can back flush it from the top past the fans...

    Can anyone talk me into spending this much on me rotors?

    The USR1070 work great with the USR Yellowstuff pads. You just need a 4mm spacer on the front calipers. The slightly larger front rotor (308 mm) stops better than the lighter 2 piece ones (300mm) when using the same pad. And about 1/6 the price. By the pics, it looks like Gruber is using...

    HVAC not cooling!

    Absolutely not! The dyes are mixed with oil and probably not compatible with an electric compressor. Adding extra oil always reduces efficiency, and the system is already weak. The best solution is not to evacuate and recharge the system, as you almost always lose a little oil when you take the...

    HVAC not cooling!

    Any shop that does A/C should be able to handle it. You don't need to worry about the service mode and the solenoids unless you are evacuating it. Since you still have pressure in the system, all you need is a recharge, unless they find a leak. There is a sight glass on the drier to determine...

    HVAC not cooling!

    You are low on refrigerant. Your pressures should be around 15 BAR when the compressor is on at that ambient temp. 35' C is nothing to worry about. Mid 40s and you can start to be alarmed.

    VMS Help

    Here is a pic of the high voltage ESS disconnect (orange), located on the left rear of the ESS by the front of the left rear wheel. You might have to take the wheel well liner off to access that area unless you have small arms. The connector with the VMS power is on the bottom (black with red...

    DIY: Roadster 2.5 PEM cleaning - step by step

    The motor shroud is in two sections that are bolted together. Every time I take those off I am amazed at how much crap is in there. Most of it gets jammed in the bottom of the motor, which would explain your uneven temp readings. You should consider taking the shroud off to clean the motor.

    Cooling cycle non-stop?

    It's not the pump that is the problem. The system was not designed to cool the battery without the a/c on. There is no air/liquid heat exchanger (radiator) to cool the battery coolant. In fact in warm temps the heat created by the pump will actually raise the coolant temp. You have to inhibit...

    HVAC Refill Procedure and replacement Condenser

    You dont need to do anything with the high voltage system for just the condensor replacement, it doesnt require you to disconnect anything related to that.

    Brake Pads

    The thicker pads wont fit and are a paint to grind down. You really need a mill to get them flat. Ebc USR1070 rotors work as-is in the rear, and just need a 4mm spacer (flat washer) under the caliper to work in the front. Those rotors you have need to be machined as least, but should be replaced.
