I just wired up my electric bike, it worked during the first power up sequence, then it is broken. Using KDC36100
. For testing, I have a 35amp fuse installed on main circuit. Also, I'm using this 40amp relay
, says it has a Diode so I didn't put one in the circuit.
Mystery throttle switch, I put a rocker switch in...not sure what that switch is for, manual says "(5)Micro_SW (white): Close to GND to activate. Default as throttle switch", switching it to pin 10 (Ground) does nothing. Actually, for the first startup, when the throttle worked, I left that circuit open.
I turn on the main power switch and the controller is stuck on full throttle, with the LED off. Also, the 1k 10w pre-charge
resistor gets very warm to the touch.
I am using this throttle from kelly
I programmed the controller for 0-5k pot (only other options are "hall throttle" and "3-wire"). I also current limited to 28% and set the voltage limiting range to 21v-28v. I tested the throttle output voltage (throttle wired red, black, white...so I put the 5v on the red and the white is signal), at 0% throttle I get 0.8v and at full I get 4.2v.
It still runs even if I unplug the throttle signal wire.
Is my controller blown?
I DID NOT SHORT ANYTHING OUT, or wire stuff backwards.
