    Will this Hall sensor do, as a replacement?

    Hi Fuelsavers, A Hall sensor in my dd hub has failed and I was wondering if I could get some advice on a replacement sensor. My failed sensor is a Taiwan Semiconductor TSH181CT and they're a little bit hard to find. TSH181CT newsletter...

    Is my controller toast?

    "Hall sensors are easily burnt out if the signal wires short to power or ground." "Reverse voltage can cause misfunction or damage Hall sensor." The yellow Hall sensor had 8 ohms between signal and ground, so it's :cry: http://www.taiwansemi.com/DSfile/TSH181_B13.pdf

    Is my controller toast?

    Is my controller toast?

    No, not really. I bought the bike not working. I started reading the forum. I built a hall tester from old bits and found the Yellow Hall Ground and Sensor wires shorted together. I got 0V at the controller Hall plug, so I ordered an ebike tester. started me looking for the regulator, so I...

    Is my controller toast?

    (48V 1500W controller; battery at 52V) I disconnected everything from the controller except the battery. With my finger on the resistors, I turned the battery to ON, after about 7 seconds I had to remove my finger because of the heat. Tested the throttle with an ebike tester - ok (green, off...

    Is my controller toast?

    I replaced the 78L05 regulator and now I get 4V at the Controller Hall plug. I touched the large blue resistors with my finger and they were VERY hot, almost too hot to touch. Do you think it's time for a new controller or is there hope :?:

    wire in a fuse advice for a 36V 10Ah flatpack batt

    Hi, I bought a batt only to find that the fuse isn't wired in :shock: Do you think there would be any harm in unsoldering the red wire from the key switch and putting the fuse in series? Thank You for your advice.

    48V dd hub on 36V bike?

    Sorry, that shouldn't've been included in the post. With all of the hub wires disconnected from the controller, I shorted two phase wires at a time; Y/B, Y/G & B/G, and felt resistance to the hub turning each time. At all other times, there is no resistance. Grin Tech: Testing for Blown...
