    Slash 4x4 Telemetry Issue

    Just bought a couple of telemetry sensors to install in the truck. Install isn't the problem. The sensor that connects to the battery terminal in order to read battery voltage doesn't fit my battery terminals. There suppose to clip right on but my battery terminals from the car are high current batter connectors. Part number traxxas says to get is #6541. Also having issue with rpm sensor. I have an aftermarket slipper clutch that does not fit the magnet that attaches to gear on the clutch. Anyone else with these issue a or have a solution? I'm a newb to this and intend to race the truck only but I had the sensors so I thought why not.

    Does your aftermarket slipper use stock spur gear or a different one?

    to correct your voltage issue it is possible to solder the voltage reading wire to the power wire from your battery(s)... all it does is read voltage and nothing else, there is no ground or signal wire comming off that so either way it will work. with the telemetry on a nitro rc, the voltage plugs into an extra slot on the receiver mainly because we only use 6-7 volts in our trucks, so it makes it easier to install.

    for the rpm reading on the truck, you have to use a telemetry compatable spur gear for it to work. with out the magnet in the gear you will get a 0 reading mainly becasue the sensor senses how many times the magnetic feild pulls on that sensor and calqulates that into rpm.

    I'll have to check to see if the stock gear fits on the aftermarket slipper but I think the bolt pattern is different. As to the soldering the voltage sensor to the battery terminals I'm a bit lost on how to go about that. It just makes no sense that they recommend that part number for the voltage sensor connector but it does not fit the stock terminals. I'm assuming they updated them in the last year or 2. I was just hoping they had a new updates adapter for the voltage connector. Thanks, for the help anyway.

    It looks just like the other one in the picture but I guess the best bet is to go to hobby shop and look with my own eyes.

    I think the only difference is one has a long cable and the other has a short cable

    Can you post a picture of the battery connector on your truck?

    Is it like this?



    Or like this?

    Yes I have the connectors in the first pic but the part traxxas recommends works on the connectors in the second pic

    OK. That's the problem then. To get this to work you are going to have to solder a wire, coming off of the red wire on your ESC. Strip about 1/2" of the insulation off in a convenient spot of the red wire of the ESC, wrap the small gauge wire around it, solder it, cover with a good quality electrical tape. I normally say heat shrink everything, but you can't in this case.

    If you are not that great at soldering.... practice on some junk pieces of wire first. I taught myself to solder when I was 12 years old. Same with welding. I had no clue how to weld, or how a welder even worked. I always wanted to learn. I eventually just went out and bought one and welded a bunch of junk metal I found out in the garage together. This was LONG before we had YouTube to "cheat" with.

    Yea YouTube has carried my butt up to now lol. But there is nothing online about this issue which is weird. Not sure why my slash has different connectors.

    Those are the "new and improved" (LOL) ones. Eventually, they will all have them.

    When you mean red cable to solder to do you mean the red cable from the sensor to the red battery terminal?

    The little red wire from the sensor gets soldered to the big (12 gauge) wire on the ESC.
