History - Wisper 705 Torque with 575 battery. It's approaching 7 years old and recently started losing assistance after about 20 miles. Stopping would see assistance returning sometimes, or it could might come and go when pedalling. My suspicion was the battery was failing because of its age and people I sought advice from didn't disagree. I chose not to have the battery tested and save the money for replacing it.
Had the battery re-celled as the "cheapest" option. First ride today, and the problem manifested itself almost immediately
Assistance came and went much like it was doing after I last rode over 20 miles.
I checked all connections (again!) and took the controller apart having read that failure of it can cause symptoms like mine.
Inside there is an overheated component and a burnt spot on the case adjacent to where the component is.
My questions are;
1 - What would cause this, and would changing the battery have any influence on the cause?
2 - Should I be looking at anything else - motor, torque crank?
3 - Is the controller repairable, or will other components on the circuit board have failed? ( Replacement is out of stock at Wisper?)
