Voltage, oil consumption, women, belt-a-thon

The CC head channel 11 voltage often reads lower than a voltmeter
held on the battery posts.  Coincidentally, I was fiddling with mine
last night; I used to get two different readings depending on the CC
system being on (Econ) or off, last night it said 12V no matter what
I did.
