runaway bike problems..

[steveo]

Hey Everyone,

So i've had run away bike problems a couple of times with my 2wd x5303 bike .. which is not as fun as it sounds... lol

i wana make sure i got the throttle linked together correctly to run my dual controllers..

so what i do is hook up my throttle to the 5v pos/neg/siginal from the primary controller.. and then parrallel the signal wire to the secondary controller..

is this correct?

what happened yesterday.. was i decided to run just the primary controller (front motor only).. and the thottle started acting weired and then went full throttle out of no where.. luckly i didn't kill myself..

any ideas?

thanks

What controllers are you using. Sound more like a faulty throttle or bad connections to me.

Tried 2 different throttles.. not a throttle issue..

Using the eb3 series 24fet controllers for the setup

This is how I run my twin controllers and never had had any issues. I would suggest that the plugs and wires are checked very carefully going into the controller also Make sure that the high throttle lock out is set the the firmware of both controller's or it may be that you have a faulty controller.

Thanks!

.. ... my 2wd x5303 bike .. which is not as fun as it sounds..

That's like and all in one sentence. ..

But yeah, i've done a few 2wd with 1 throttle, wired same as above and have never had that problem... am very curious to know the root cause.

sorry, its called throttle blowout protect in the software I use (XPD)

I'd suspect a bad wire connection in the ground wire somewhere between the controller and the throttle. Double check all the connections. Otherwise, when you turn off the unused controller, how is the power disconnected? The ground (battery negative) of both controllers should always stay connected.

I had second controller unplugged!!

I will keep this in mine.. had no idea..

Ill check the software for throttle protect

Keep yall posted

The BEMF from the unused motor could generate voltage enough to power it up if the phase wires are still connected. I think if you keep the ground sides of both connected, you shouldn't have much chance of back feeding the throttle.
