Quote from: Franklueck on October 01, 2024, 01:48:26 PMHi Guys,
I am experiencing intermittent power loss of the motor, symptoms are the bike runs great for a few miles then then the motor / throttle stops responding, All lights and controller still powered up, I tried disconnecting the brake connections with no change, tried checking all electrical connections good but if I disconnect the Battery then reconnect the battery the motor starts working again, My bike does have a few miles (3400) and other than that the bike runs great

Does anyone have any suggestions why this is occurring?

See my other post here - might help you..
"I cut off the stripes holding the engine cable - disconnected the engine cable (closest to the wheel) - connected back again and now it has run without stop for 3 days... Yesterday, I experienced the engine kind of 'jerking' – as if it dies for half a second and then starts again. This happened while driving at 30 km/h..

The engine has been through three hard winters with a lot of snow etc. Can it be the engine that is coming to an end of its life?? Can you change the engine cable or do some magic to it?"

I have the same issue...

I have kinda the same problem with my radmission 1. PAS typically dies (controller and lights still work) when I go for a while and then brakes. Then after 1-2 minutes and sometimes faster / longer, it starts to work again...

Quote from: RadMagnus on January 26, 2024, 01:50:51 AMHi again - so I'm ordering wiring harness and batteryconnector from Rad. It is going to cost me 36+36 euro plus shipping. Anything I should add to the order while I'm at it? The Radmission is 3 years old. Already got new battery, two displays. The PAS sensor is very exposed to moisture etc - is that something I should order or is it easy to get from 3rd party? Thanks!

Realized I never went back here. So I bought the wiring harness and that did the trick

Thank you for all tips!

The PAS sensor is just a magnet so I don't think you will have problems with that.

If you don't want to install the connectors, I think RAD sells the battery cradle for $25US.   

Hi! Thanks. I researched the connectors and it wasn't that much more expensive to buy the cradle from Rad (36eur). Hopefully that or the wiring harness will do the trick.

Here are search words

Hailong Battery Male and Female Connector Plugs

I got the ones with soldiered wiring attached

Thanks! Just saw this one (didn't realized there was a new page to the thread). Ok, I will get that one!

When one has connections that are covered in corrosion and the system has stopped working one needs to see where the problem lies. Corrosion can creep inside sealed wires as it is considered a galvanic type of growth. Where a wire goes, corrosion can follow. Thus the need for a continuity test. In this case check the continuity from the controller to each of the pins in the connector. If you have continuity in all of the pins/wires then you need to check continuity from the other part of the connector to the motor plug. Again, if continuity is good then check continuity from the other side of the plug to the motor.
It's the only way to see what part of the wiring you need to replace. Sometimes one can replace just one wire, other times just a part of a wiring harness. Often the entire harness needs to be replaced.
This test will also determine, if all of the continuity checks out OK, that it may be your controller and there's additional tests for that. I don't know how to test for a controller so, if this is your case, then others will need to chime in.

The battery connector can't be that expensive. Anyone that knows where to get one fast online?

Thank you! I might have to buy a multimeter...

I?ve went through all of Rad?s steps in the guide and it seems to be the wiring harness or battery connector. Does not turn on if I disconnect as per their instructions:
Pedal Assist Connector, Motor Connector, Taillight Connector, Rear Accessory Port (if nothing plugged in then continue), Brake Connector - left and right, Throttle Connector, Front Accessory Port (if nothing plugged in then continue), and Headlight Connector.

Have you disconnected the headlight and tail light and seeing it will run disconnected? 

Have you installed an aftermarket headlight?  These have caused an overload of the controller. 

My problem was the battery cradle connection melted wiring.  I had to replace the connectors.  You might have to do that or replace the cradle.

This was green in the bottom before I cleaned it. I wonder if that's enough or if it needs to be replaced... I will update tomorrow after I've done all the steps in the guide from Rad...

And no - no aftermarket parts except for the eggrider...

Hi! Thanks for replying! I have now received a long instruction from Rad and I will try it tonight. This include disconnecting one connector after the other.

I Believe I did this when I was troubleshooting without success. But I will try again in a more structured fashion!

melted connectors, yikes!! I will have to check that.

... I have tried with my spare battery. ...

Well, that rules out issues with the keyswitch.

"Pictures here"? What pictures?

Thank you very much for pointing that out! I've tried to upload but it fails. I'll try here in this reply as well.
