    Voltage sensor install....

    Red wire when installing the voltage sensor....

    I don't want to use the 1st Gen connector or power tap - so I was thinking of removing a small piece of plastic covering the red battery cable at the ESC end and soldering the voltage wire to this.
    Any problems with doing this??

    Another alternative could be to open the ESC and solder the wire inside the ESC alongside the battery cable.....

    Anyone done either method?

    I've moved the power tap wire to the newer ID plug shape many times, not an issue. I wouldn't mess with tapping directly into the ESC, it's far easier and safer to get power closer to the battery.

    Ordered the voltage/temp combo # 6521.
    Unless im missing something theres no jumper plug to deal with rewiring for the battery.

    No, they expect you to buy the 6541 power tap, which connects to the red plug on the 6521 sensor.

    BUT before you can connect the power tap to the battery you need a 1st gen battery connector!

    You also need the small 6535 mount to attach the temp sensor to the motor!!

    Buy one thing and have to buy 3 others to install it!

    As a result rather then faff about with a 1st gen connector etc, I'm going to just lengthen the red wire from the sensor. Then remove the red cable from the battery plug and connect the red sensor wire to it, before re-inserting into the battery plug. Tidy up with some zip ties, and job done.

    So, finding the above very true once installed, i ran a solid copper bell wire from the red connector in the reciever box yo the batt connector. I have a HW1080 installed, so no need for a 1Gen power tap. Instead i drilled a small hole in my xt60 to stuff the bell wire into for voltage. It worked great at home!!, then went to my local crawler course, and didnt get voltage or temp on the app. ***? Havent checked today, but will check tomorrow. I used a ziptie, a shaped block of aluminum instead of the temp mount, but i like the traxxas temp mount better than mine.

    Just remove the positive wire from the esc connector, wrap the sensor wire around some of the exposed wire between the pin and the insulation, solder it, and reinstall the pin back into the connector with the sensor wire soldered to it. Thatís what I did and it has been working fine.

    +2, i just opened the xt60 and the back of the soldered pin was already exposed, so i just tacked my wire right to it with a little fresh solder. Working now.

    I just disassembled the connector, and soldered the wire for the voltage sensor to the + tab.
    And for the temp sensor.....a drop or 2 of shoe goo will hold it in place on the motor can just fine.
