    DC/DC converter hook up help.

    I see 3 way of doing that: 1- if you can open your controller and have the proper schematics you can hook up the 12v (or maybe 14v) power line which should be inside your controller. in you dont want or cant do this... 2- if you have a led battery meter which turn on only when your controller is...

    Problems with ebike

    First: what is your controller model? this can be helpfull Second: Take a multimeter and start investigating: 1-measure resistance (ohm) between the red and green(or yellow on some, but not the black one) which came from your throttle, with your controller OFF (NOT connect it to the battery...

    Unusual hall problem,due to controller KU63 :workaround

    No luck using an external battery, my controller doenst like it and it doesnt work at all. If a defective 78l05 is responsible for this transient failures, how can i test it (since the failure seems intermittent)? Can i replace it with a 7805 regulator(i already have) or some better one? I...

    Unusual hall problem,due to controller KU63 :workaround

    Ok, i'm almost sure i have a problem whith the 5v power supply: if i connect the hall sensor, after few seconds, i have the usual failure in the 5v line; so i disconnected everithing (pas, hall and brakes) and i let connected just the throttle and phases, and i run the motor, while measuring the...

    Unusual hall problem,due to controller KU63 :workaround

    I tested the hall sensor ,disconnected from the controller, with a multimeter, it seem to work: i measure 0 or 5v on the sensor wires, which switch (0 and 5v) as soon as i move the wheel backward. So it seem to work properly. Before connecting the hall sensor, i have a 5v on both throttle and...

    Unusual hall problem,due to controller KU63 :workaround

    If i didnt make any mistake in my measurement this is exactly what happened to me. I first thought it was a hall sensor problem, but they work fine when not connected; now i'm checking or replacing every connection (cable, some of which were a bit too long, and plughs), but i dont think i'll...

    Unusual hall problem,due to controller KU63 :workaround

    I couldnt measure the hall sensor consumption, i'm not sure why, but maibe is too small for my multimeter. Anyway i disconnected everithing in order to measure the consumption from battery (i have no cycle analist, just a multimeter), and.... seems that my sensor are not broken! I tried to...

    Unusual hall problem,due to controller KU63 :workaround

    I measured the resistance between black and red and is high, but maybe not enough (at the beginning 1000kohm, then slowly fall to 600khom); but the strange thing is that i also measured the resistance between each wire and between each wire and the motor cover and i always measure almost the...

    Unusual hall problem,due to controller KU63 :workaround

    for gwhy! yes, i have 5v out on the wires red, blue, green and yellow, but as sson as i connect the red one to the hall the voltage bacame unstable. I didint understand what you mean by about " having a sort on the 5v line into the hall sensors, this will shut down the 5v line"

    Unusual hall problem,due to controller KU63 :workaround

    for edavinci: thanks for the clue, i'll check, but i dont think that is my case: from your picture seem to be a problem in the battery case connection, anyway i do not experience a power cut, i still have power, but my engine do not work, or better, it does a bit if i keep accelerating and i...

    Unusual hall problem,due to controller KU63 :workaround

    Ok, first thank to dnmun for your help. This is what i've done: I've Disconnected everithing (pas, throttle, battery-meter, phases etc..) except from the 5 wire connector of the hall sensors; my measurement are not 100% trustable, because after few second voltage always drop so i took the first...

    Unusual hall problem,due to controller KU63 :workaround

    I'm not sure i can make this mesurement, since when i measure the voltage it immediately drop to 0. If instead of measure it i just put a led between + and - it just blink(it should remain on, but seems that the voltage continue to drop from 5v to 0v intermittently). I dont know how to explain...

    Unusual hall problem,due to controller KU63 :workaround

    I'm not sure what you mean by "input voltage to the controller", if you are speaking about the red and black cable on the controller side of the connector, i can measure 5 v (on the red cable +) for one second, then the voltage fall rapidly to 0v, instead between the black (-) and any of the...

    Unusual hall problem,due to controller KU63 :workaround

    I edited this thread, since i've found a workaround for my problem, so if someone will experience something similar, here is my solution. I must thank people from this forum who helped me find out the which was the problem; i also found a lot of help(not here) and information from another member...
