Rad City power issue

[mbates50]

My wife has the Rad City 5, probably 2 years old, with a Bolton controller. All has worked well until recently.
Occasionally, she will have no pas or throttle power for a second or two, then all is well. I can?t get Rad help due to the controller.
So could it be that the battery is beginning to fail, or the Bolton controller is the issue?
Any ideas would be appreciated!

I have had a similar problem with my 2 year old Radrover 5, (all stock) Mine would give me the exact same response as applying the brakes, To resume all I had to do is touch the brakes and all was good, After a year Rad customer support and myself figured out it was faulty sensors in the brake cables assembly,  To troubleshoot the problem my technique was to disconnect the brake sensor safety  both front and rear for a while, Sure enough, found out  the brake sensors to be the culprit.
Hope this helps, Paul

Rad sent me new brake levers to replace stock ones, It did Not fix the problem, Rad told me that the whole batch of brake levers had some issues, Yes, even some of the replacements. So, I am living with the problem since I am now out of warranty, And the fact that Rads customer support has not been up to par lately, My intermittent problem only happens about once per ride with the replacement levers, So I have been living  with it.

When it happened to me, the problem was a tiny bit of moisture in the 35 A controller from Bolton. It would happen in the first mile of riding with very little power assistance. I opened it up and dried with with a hair dryer. Later, the problem recurred. When I dried it, I sealed it with RTV. There was no more trouble.
