> Many people do not replace the SI Board but merely solder in new batteries. I did not feel confident with this approach. After seeing how the blown battery had leaked acid all over the circuit board I was glad that I had purchased a new one (rebuilt actually, obtained from Stephen at South Motors BMW) do you really want to do that? why not just buy a new one? what exactly is this board for? I dont see why the power wouldnt be tied in with the cars electrical system, opposed to using batteries ---

If you really need help doing this PM me, but i think it will be more reliable and hassle free to buy a new board ---
