Also known as 11-008, that's the one that Bosch says is correct for 
Beetles, but I say is the right one for us (and wrong for Beetles.) 
Make sure the spring is pressing down on the ramp and not on the 
corner at the top of the ramp. If it just touches the corner, the 
brush may stick and you'll have to push it down. This will only 
happen when the brush is new and full length.

The voltage probably won't increase because that's controlled by the 
voltage regulator. Your 14.1 V is actually quite good, and lower 
voltage at idle is normal because the generator can't put out any 
more at that speed.
