Wow! My first V post. Thanks for such a great board.
My bike runs on 48V through a 36V/20A Crystalyte controller to a 407 motor. I added a block of Andersons to the motor leads so I could disconnect my battery bag easily. I've noticed that one of the three cables seems to be getting hot enough to make the Anderson housing melt a little. I'm pretty sure I have the 30A Andersons. Any ideas why this would happen? Could my soldering be at fault?
Thanks so much!

there could be a poor connection within the anderson connection causing above normal heat build up?
or it could be the result of heat conducting from the motor, rather than heat build up from the connection itself.
or it could be the 36v/20A crystalyte is rated battery side, in which case motorside amps will be *much* greater at low speeds.
i would go for a ride and use a clamp meter to measure the current on the motor side (or one of the phases it its AC).

Since it is just one of the three connections, I'm betting on a soldering problem. It is not easy to make solder joins with that gauge wire since the copper wire is so efficient at conducting away the heat.
