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.

A Kelly throttle is a Hall throttle

dont need throttle switch

Ya, apparently if you set it up with a the "5k pot" for the throttle and use a Hall Throttle, the controller fails.

If you need something done, then you have to do it yourself...

50 amp rated hall current sensor using arduino:
http://arduino.cc/forum/index.php/topic,109400.0.html

and the Arduino Nano also controlling the H-bridge (IC Driver IR2110) using some big n-mosfets and current limited feedback (with the above current sensing system). Radio Shack should have another breadboard in stock =/ I already have all the parts in stock, but because I need this much earlier to display, I just purchased an off-the-shelf POS, until further notice we'll see what Kelly says...lol

Measured 0 ohms between M and B- terminal with the unit detached and not installed...that is probably not good.

Tell Kelly what happened even if its out of warranty
they might be able to fix it or show you how to reflash it

Yup, they are working with me via email, now asked for serial #. Time zone issue kinda sucks, 1-question / 1-answer per night =(
