x52006,
And, from my fading memory, I seem to recall some posters doing a total unhook, meaning disconnect the batt at neg, let sit a couple mins, and reconnect.
I realize that it's not handy getting to the buried batt, but it reads like you are going to need a new batt anyway. A new batt may also cure your current glitches,
but that's just a guess.
