Heyy, so lately my team and me have been stuck with a constant issue, our robot is moving well, we have a swerve drive but sometimes the encoder cable of the spark max breaks. Aprox 3 times a week we get this same issue, I was looking for options or tips of how to prevent this failure.
Any tip is welcomed, thank youuu
Hello!
Team 694 usually hot glues the encoder wires to the housing. We also try to pry the encoder out with a small screwdriver when possible.
yes and move the sacrificial, consumable terminal to where it’s easily and cheaply replaced with this.
I contacted JST for instructions on proper technique or a tool to remove their terminals and they tried but didn’t understand what I was asking even with multiple e-mails and a drawing. (They were the Web Contact Us in Japan.) Then I couldn’t get through to my area distributor. Wish I had OP’s image. Maybe someone else would have better luck - start here.
I made a puller from an IC puller but it requires a very careful, accurate and strong touch to avoid destroying more wires if it slips. Beyond the students’ general capabilities so it’s hidden in my computer bag and rarely used.
Yes!
However, as a team we don’t like these because of the concern of an additional point of failure.
When we have the time, we usually cut off the terminal and restrip and put new connections on.
We bought these jst connectors and housing from digikey last season to make custom wires for our rev through bore limit switches because the provided wires weren’t long enough.
We still hot glue afterward though to prevent shorting and more pulling out of the wires.
This isn’t necessarily the solution for everyone since they are relatively difficult to crimp. (They are very small 
)
We use this crimper from molex to crimp them and they are similar to the terminals used for PWM (We use this crimper for our pwm as well!)
