The 68 M20F is a 14 Volt system.  I have no idea if that is common across all the older Mooney's.

They were all 14v until sometime in the early 80s

I have a 1985 M20K 231.  It was the last of the 14V for the K models.  In 1986 the M20K 252 was 28V.  Not sure when the J’s moved to 28V.  All earlier models were 14V.
