corrosive battery

[Eduardo Saponara]

I don't know if this has any relation to your cs-20 problem, but the cs-5 owners manual states in the trigger section about the control volt and trigger in/outputs
 
"wrong connection of these controls can cause damage, so careful attention should be paid when making connections" p.16
 
I don't know what kind of damage can result, or what kind of wrong connections would bring this about.  maybe it is something exclusive to the Hz/V standard?
 
 speaking from a position of profound ignorance,

    What is a good supplier for replacement batteries for a Jupiter-8, a Juno-60, and an ESQ-1. It is probably about time for me to replace the batteries.  Also:
        1.)Does anybody know where I can get schematics for a Roland SH-101.
        2.)When I went probing around (unfortunately I was not using my X10 cable for my oscilloscope) in by Rhythm King (slant faced model) I must have shorted some of the FET's. Is there and easy way to test them without soldering them away from the board and testing each one? 
        3.)My Yamaha CS-20M mods were completely successful until one day...  I put in a modulation input into Osc1 and the filter. I also put a output jack for Osc2 and Noise and an input jack for the filter. All was fine and well until I decided to use my old Polarad 1020-A oscilator as a modulation source. Since then, it has decided that it doesn't like to be a synthesizer anymore. It depresses me because it worked so beautifully for at least a year and a half prior to this incident. The Polarad worked great in the input to the filter, but just destroyed it when used as a modulation. If anyone has some helpful hints in what I may try to restore the synth, please let me know. -
        4.) actually, schematics for any of the above equipment would help.  Thanks,
