I wonder if anyone could spell out for me (in as much detail as possible) how to “shave the current shunt” on a KU63 controller. I’m expecting delivery of the various parts to electrify a Brompton and from reading many of the forum pages it seems others have done this to reduce current from the set 15 Amps to around 8 Amps or so.
I found a good explanation of the KU63 controller here
KU63 motor controller
But after ploughing through that I’m still hesitant to do anything other than disable the pedelec control (should I need to).
That web page has a bit about INCREASING the motor current, but nothing about REDUCING it. So, please, can anyone help me?
I suppose the other option might be to use the three speed option of the ku63 and ensure that only the lowest speed was ever used. Would that work?
As I understand things, the 3 speed switch is a throttle limiter so (I think) should reduce both current and voltage. But is that correct?
And then the next option might be to disconnect one of the three wires to the 3-speed switch on the controller ... I wonder would that option have the same effect as saying “never use setting III !?”
