Out of curiosity, why did you check the voltage? Are you having some other problem? Does there appear to be any damage to any of the wiring to/from the battery? If there is too much juice, could be an issue with the generator or the rectifier...

Sounds like there might be something else going on though.

Well, the charging system is actually pretty simple... not many things it could be... 2nd battery? Why did you have to change them? What were the symptoms?

there should be no acid in the battery if they were serviced correctly

Sounds like a rectifier / voltage regulator issue. You shouldn't be seeing anything above 14.4 VDC from memory. Pull the manual and double check. 16 VDC would be cooking your battery.
