The quickest way to solve this is to take a 12V test light and start at one end or the other -- at the rear lights or the headlight switch and see where you have power and where you don't. A quick way to check for a bad ground is to provide a substitute ground straight from the lamp socket to a known good ground.
Fuses can look fine and still be bad -- check for power on both sides of the fuse.
You can use a voltmeter, but it's easy to get fooled if the circuit isn't complete. With a test lamp you're actually proving that the circuit can supply some current, whereas a voltmeter doesn't draw enough current to load the circuit properly.
