  • Issue with newly chipped Evolution to Digital car

    I have digitally chipped (27632) over a dozen Carrera Evolution cars and never had any issues. This morning, I did the same as usual for a new analog arrival (an older but digitally-upgradable Cobra), but have run into a problem. With the polarity switch positioned to the left, the car will code to the controller. However, it will not move at all. It DOES move, however, if I face the car the wrong way on the track (facing counterclockwise). BUT- it doesn't run forward, it runs BACKWARDS (clockwise, as in the normal direction, but drives in reverse- rear axle leading the way. On top of this, if I flip the switch to the right, it will do just the opposite- when facing clockwise, it will run backwards- counter-clockwise, rear axle leading the way.
    I used two different digital 27632 chips that I know for a fact work correctly, and it does the same thing with each chip installed. I have made sure that the connections are correct and none of the wires are touching. My other cars code and run properly. Same issue on multiple controllers. I've never experienced this before so any help would be appreciated.

    Check the polarity of the leads to the braids and also the polarity of the motor hookup. Something is backwards…

      Reverse the position of the wires soldered at the motor. All will be well. It will code and run forward in both directions (as it should).

        OK, I see it now, thank you! Apparently, the purple wire should be running to the front right of the motor, but it is on the front left. I happened to have a duplicate car that I'm using for parts, so I swapped motors and it runs beautifully now! I guess I'll hold on to the reversed-wire motor until one day in the future when I develop some confidence in soldering tiny wires such as this (hopefully within the next decade or so Lol!).
        Thanks for all your help! I am curious as to why this is reversed. Even though the car was manufactured in 2013, I purchased it new from a reputable business and I can tell that it is new and unused (I wasn't about to send it back, regardless Lol). Could this be a factory defect or something to do with its analog status?
        Maybe it's a rare collectors' item that I could sell for $10,000 and recoup some of the money I've poured into this hobby!!!

        Take care,
        Dennis

          The only other problem could be that the rear axle is inserted in the opposite direction. If you can, try to flip it over and see if it solves yor problem -- that might be an easier solution. You mgiht have put the axle in backwards when you serviced the car.

            The rear axle was exactly where it should have been, both when it first arrived and after I serviced it. I was thinking about flipping it around just to see what would happen, but wasn't sure that wouldn't do some harm, so I swapped out the motor first and would have waited for an expert opinion from one of you guys before attempting that. It was definitely the motor, as the replacement works perfectly without any other experimentation. 20211022_173959.jpg Here's a photo of the offending motor, the wires are reversed from others, as the purple is on the left and gray on the right. That stain on top was there upon arrival. Corrosion due to age (2013)?

              For future reference, the only way a digitally chipped car of ANY kind (Scalextric, Carrera, Ninco, SCX, oXigen, Scorpius, whatever) will go in reverse is if one of these two things are the case (usually the first one, as you've found).

              1) the motor is wired incorrectly (backward/reversed/whatever). This is SUPER easy to do, and is why I test motor/wheel spin before soldering the wires on.

              2) the axle of an inline drive car has been installed the wrong way around. This is much less common, since the gear usually has an opening or trough it must fit in to function properly, and it will not even snap in if reversed.

              The wiring from the braids will NEVER make a DIGITAL car go in reverse. Either it will function, or it will not function, if those wires are reversed. While it may do that for analog cars, it simply can not do that for digital ones. I don't care what the system is, or what kinds of switches it has on the chip... there's not a single chip on the market that will take inverse polarity from the track and translate it to inverse polarity to the motor. I hesitate to say that such a thing is impossible, but I will say that such a thing is not currently possible with existing digital slot car chips.

                That "stain" is residual solder flux, which indicates that the motor was "serviced" by someone post-manufacture, and they did it backward. I would not be surprised if they didn't know that the switch on the bottom was for polarity, or the original analog "chip" had been removed, and they wanted to run the car on a track with opposite normal directional polarity. Either way, that motor has clearly been messed with.
