Front hub problem.

[Wayners]

I've got a front hub problem and I'm not sure what is wrong.
As I'm riding I get a sudden large amount of vibration from the hub and a horn like noise. This is followed by the power cutting in and out maybe 4 times a second. Then it fixes itself and I'm going along nicely again. Happens about every 3 or 4 minutes.
I thought if it's a hub problem it would remain but it don't.
Any ideas?

I've checked all the connectors by pulling and pushing back on.
Should I Keep riding in the hope it gets worse?

Thanks

It sounds like a bad/resitive phase connection. Look for any signs of heat damage, discloration or burning/ swelling.

Brilliant. Thanks @Benjahmin
Found the problem.
Cable rubbing against front tyre. Can't upload picture as forum error but I'll update later after I've fixed. Must be shorting out cause electrical fault

This was causing the vibration and noise.
I'm chuffed I've fixed it as I was worried about further damage

Don't let the motor give power when it makes that noise, otherwise you can blow the controller. It's a connection problem between the controller and motor. Make sure that the motor connector is pushed in ALL THE WAY TO THE LINE, not just in tight, then have a look at the wires coming out of the controller to make sure that they haven't melted. It can also happen when you damage the motor cable where it comes out of the axle.

Seemed to be the thinner wires. I've been on a test ride and all good so I think I got away with it
