    Any Help on Identifying a Controller and it's Markings Code eWheels ew-19/ew-20

    Ok, I could be wrong, but I just did a search again using "ew-19, ew-20, ew19, ew20, ewheels" collectively and individually, and it did not even return THIS thread !!! That is a basic Boolean search which should have returned ANY and ALL comments, posts, threads that contain any one or part...

    Hard to believe that no one out of 56 thousand Members has any experience with this eWheels ew-19/ew-20 Mobility Scooter ... not 1 other post about them.

    Any Help on Identifying a Controller and it's Markings Code eWheels ew-19/ew-20

    Oh yeah, it {they all each} connects to a flat pack mini resistor, then on into the rest of the circuitry, but no "shorts" anywhere else on the board. And if there is no other voltage apparent coming out of the controller, then, every Red wire coming out of it must be 48v... and they all do...

    Is there any chance that these cheap small controllers have a buck-converter built-in for outputting 12 or 24vdc ??

    Any Help on Identifying a Controller and it's Markings Code eWheels ew-19/ew-20

    Thanks, but, can't check THAT because the controller is blown... so I have just those 3 wires coming out of the head display unit... the black by itself, a yellow and a orange in a connector - they do not short to the black at all, no ohmx at all... but they together DO short together for...

    Thanks, and sometimes it's just little pudgy fingers that don't know what they are doing, fiddling around with stuff that is way beyond their pay-grade !!! {the owner of the trike - a friend} but it worked fine until it didn't, and those pins don't short to anything on the pcb, it is only a T/B...

    And by the "software" you speak of, you mean "Firmware" because it is "embedded" in chip... unless the "pin points" labeled "YY-SDA- -GND" are supposed to be for a 4-pin stand off connector for a Programming cable ?? I can make that easily enough if need be ... The MPU/CPU chip, 12 Legs on each...

    Any Help on Identifying a Controller and it's Markings Code eWheels ew-19/ew-20

    Thanks for the reply... Well, I have already removed all 9 MOSFETs, would I still check for shorts between where the legs were to both Ground or Positive ? Because, on the board, the center pin {2} of every third of 9 mosfet shorts to Positive, and pin 3 of 1&2, 4&5, 7&8 shorts to Negative, all...

    Any Help on Identifying a Controller and it's Markings Code eWheels ew-19/ew-20

    Greetings All, I have searched many forums and all over this one too before posting. I can not seem to find out ANY information about a Controller I took out of an eWheels ew-19 {ew-20}, and it is the original. The Company says they have "no Idea", and there is NO label on, or in, this small...
