    Thx for the explanation. Very helpful. I will check out.

    Capacitors in KT Controller blown

    Thx, yes i do know k means a 1000 times, that was a typo, my bad. Perhaps you are right about the shunt overheating too. Will order a few resistors of values suggested by people who responded to my query and try them out.

    Yes i had tested the capacitors and they are fine. thx

    Capacitors in KT Controller blown

    Thank you everyone. I will order a few resistors in the values that you all suggested and try them. Hopefully it is the resistor that is the problem and hopefully one of them will fix the controller. If not i will try to find the fault in other areas and if i cant find it, i will bin it. It...

    thx for the effort. If you are right then my resistor is fine as it shows a reading of 198 ohms. Which only makes life more difficult, as i have to investigate further and find where the fault is at. :)

    thx for your response. The second one is definitely black, the 3rd definitely dark brown. The first one is light brown/ copper. Cant tell for sure. Yes i do get Mathew. I just like to tinker, thats how i ended up blowing it thrice :). Both my capacitors are 470uf 63v.

    I am confused too :)

    Capacitors in KT Controller blown

    Yes i know they should be bought as a set and they are cheap. As i wrote in another post in this thread, i already have another set and have my bike up and running. I just find it a waste to throw away something that can possibly be repaired for a few cents. Besides it is quite a kick when you...

    Capacitors in KT Controller blown

    Thx for the suggestions and the explanation. Yes it is indeed quite difficult to determine the colour bands of the resistor, in the pic i posted and also when i look at it. It is a large resistor 1.5 cms in size and grey in colour. The band colours are a bit confusing. My best interpretation is...

    Capacitors in KT Controller blown

    I thought so too, i had that happen twice before and my controller worked fine, the 3rd time it happened i thought it would be fine, but this time the display came on but the throttle stopped working. The motor is fine, it works with another controller. I opened it up and found the shunt was a...

    Well i had a proper short, sparks and burning wires smell

    You are right. I did indeed short the controllers positive with the negative, but the battery was not attached. I tested the resistor out of the circuit and it showed 198 ohms. I checked the mosfets, they are all ok. Visually the capacitors seem ok too.

    Thx for the info. Are you suggesting i replace it with a 82 ohms/3 watts resistor?

    Thx for the speedy response. Attached is a pic of the resistor on my board. Like i said i pulled it out and measured it and it shows 198k ohms. I dont know its value, so i dont know if its busted and whether i should replace it or not. Attached is a pic of my controller model.
