Dead BBSHD

Post by Stu Summer » Oct 30 2018 8:50pm

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?

How many miles are on this thing and have you done any repairs on it so far?

Is this the same BBSHD that was blowing BMSes and fuses when you plugged it in?

No. It is a different one.

but are you using the same battery?

also in the controller there`s a white multi-plug that in my HD was not properly pushed home, gave the same problem as yours,

but check with a different battery if poss.
