Don't feed my car after midnight! Or else I get electrical gremlins!

Ok, here's a new one. The lower the voltage in my car, the higher my tach 
goes. I know this sounds off the wall, but this is the problem: The lower the 
voltage in my car, the higher my tach goes. If I turn all accessories on, I can 
get the voltmeter down to the second notch. And when I do this, the tach will 
jump to 1500! The engine however doesn't increase speed. Is this just 
another electrical hang-up the car has, or is this the sign that there may be 
another problem?
