Hi,
I just wanted to give a heads up on the BMU if it has seased.
I had some kind of failure in the BMU on my K75 -89. The red warning light stayed lit after pressing the brake levers.
I opened the box and found that there were just a few components that could be culprit.
The problem was to find a reseller of the components since the IC's seems to be unavailable in US or Europe. I found them on a Chineese website Alibaba.com and gave it a try.
The components i ordered was:
Transistor: BC517
IC: CD4011
IC: ULN2455A
Since the cost was less than 4$ I was willing to take a chance on this.
Surprisingly they arrived by mail after about 1 month, so I removed the old parts and put the new ones in place. This fixed the problem :-)
So if you don't want to spend a fourtune on a replacement BMU, this can be a possibility.
Kind regards
