    SI board question

    What does this little switch do? it is by the negative terminal of one of the batteries. Its a high res image so if you know and have 56k just let me know, if you need to see the switch its the little silver box thath the arrow is pointing too. Thnaks

      The only switch I know about on the SI board is the on/off switch. It's to keep the batteries charged before the SI board is installed.
