I received my Rottendog rectifier board today (BPS918) and it looks the same as the one currently installed.

On this page however, there is a warning about desoldering/resoldering, complexity, only skilled repair people to attempt etc:

However, as the top of the page it says "direct replacement" so I am wondering if I simply plug it in or if I need to make some mods.

I won't proceed until I get clarity so I am hoping someone here has done a replacement and can offer advice on how to proceed.

Tks
