    BBSHD dead, display, pas, brakes, everything seem normal.

    I started out on a ride just fine. 1 minute in, PAS 1, it dies. I stop, give a little throttle a few times, hints of a jolt in the motor a couple of times, then nothing. The display reveals nothing unusual, no errors. Fully charged battery displaying full voltage on the screen. I tried to restart it without brake sensors, without gear sensor, without speed sensor, same result--nothing. I opened the controller cover to see if the plugs were seated. All good.

    Any ideas?

    With your speed sensor connected, everything on... Does it's LED light up with no magnet in the vicinity?

      No, only when the magnet goes by.

        I was under the impression that it was opposite... but I suppose if the controller just gets a pulse regularly all is well... The good news being your 5 vdc regulator output must be working, and that your controller in being energized. Carefully checked all cables and connectors for damage? (sorry, had to ask)

      I've seen where a poor battery connection will act like this... Let's just enough power thru to power the display but has no potential for anything else...

      Have you tried another battery If you have one, if not using a charger?
      Have you tried bypassing the display? Both a which are discussed here...

        A big shoutout to Tommycat. The problem was an almost broken battery cradle wire/crimp connection. Enough voltage got through to run the display but not enough to run the motor. I finally bought a real crimping tool and the problem is solved. Thanks so much because I was an inch away from buying a new controller, which would not have solved the problem.

                  Hi secretservicecycles,
                  And welcome to the forum!

                  I'd start with the thread below... after double checking the battery connections. Had it long?
