How to wire a voltmeter

["Shannon Muncy" <shannm2@triad.rr.com>]

Since I've upgraded and rewired my alternator with a Bosch unit, my ammeter 
only reads discharge (I was warned in the "how to" article that this would 
happen).

I've since purchased a used voltmeter that I intend to replace my ammeter 
with.  Does anyone have a how-to article on how to do this... or at least 
tell me what not to do?

Thanks in advance,
