Powabyke starting to play up :-(

[Deleted member 4366]

Is the problem happening round about 15mph?. If it is, it's the normal speed limit on power.

If it's doing it at all speeds, is it only doing it on hills and other times of high engine load?

They still sell a spare cable loom for your model should it turn out to be a wiring fault:

Personally wouldn't ride the bike or until you sort that ... if the throttle sticks or breaks you may not be able to stop the bike..

As John says, there are no brake cutouts on these & assuming it's the same as the x6, throttle only operates when the pedals are turning, so cutouts are not essential.

Hi thanks all, it cuts out at any speed. It is getting worse I'm sure so hopefully it will make it a bit easier to diagnose. It's fault is their in pedal assist and motor only. I have just checked connections on battery compartment and all seem tight and ok.
It is currently on charge then I am goin to run bike off the ground and see if it still does it?

 

[ady347]

Ok so I tried running bike on stand with motor only or pedal assist and it isn't cutting out?
In the meantime I noticed when its off the ground in motor only and you pull back throttle and close, when the wheel has slowed down to nearly a stop the motor is almost pulsing and keeping the wheel slowly turning is this normal.

I've got a nasty feeling that your controller's faulty.
You could try unplugging the throttle to see if it does the same. If it stops, it's probably a faulty throttle, in which case you need to dismantle it and check the hall sensor solder joints. If it doesn't stop, not so easy to fix.

 

[ady347]

The problem their is that when you switch bike on and its on its stand, the wheel doesn't turn slowly/motor pulsig until after you pulled back throttle and let it go.

 

[Deleted member 4366]

Is the throttle sticking? Does the wheel stop if you push the throttle back as far as it goes?

 

[ady347]

Just broke down on way to work. Pull throttle no power to motor just led's on. Think it is the throttle as when I pull throttle and switch on it won't do diagnostic check. Goin to bridge connector plug on throttle on break later and see if motor kicks in.

Their are 3 wires yellow, red and green. Anyone know which I bridge?
Thanks

Red will be 5v. I guess yellow as 0v. Put your meter between red and yellow then red and green to see which gives the highest. The highest pair will be 5v and 0v. The remaining one, which might not be stable enough to measure will be the signal wire. Short it to the red to give full throttle.

 

[ady347]

Ok cheers no tools at work or multimeter so I think it will be time for eeny meeny miny mo!!

 

[johnc461165]

My thoughts are the same as d8evh most likely a controller fault, you don't seem to have power cutting off due to a bad feed to the controller etc. the fault would appear to be more controller throttle related.

 

[ady347]

Have had a play. And managed to get motor working, I have to turn key on then connect wires else it goes into diagnostic mode! Will keep my hand near ignition goin home ready to shut off!

Found a throttle on eBay just waiting reply from seller to see if its compatible.

Or when I get home I might dismantle mine and see if I can get a new potentiometer from maplin.

Quite handy with a soldering iron!!

My other toys thought if share

Most controllers have built-in safety. They won't give power until they have seen a zero throttle signal.

 

[ady347]

Temporary wired in a push button switch on handlebars to get through next couple of days. eBay guy is sure throttle will work so ordered one and see how that goes.
Thanks everyone for help and advice

 

[Deleted member 4366]

Why don't you repair your existing throttle. I guess the wires have been pulled and the bare bits at the hall sensor are touching. You probably only need to straighten them.

 

[ady347]

yeah I am gojng to strip it down, trying to keep a couple of spares too for any future problems
