Electrical problem technique?

I've had some sort of electrical problem with my car since i got it where my voltage is low, regardless of the alternator/battery combination.

I was wondering, what if i were to start the car, and start pulling fuses from the fuse box, to see if the voltage rises, and then i could pinpoint which accessory is drawing too much voltage.

(these fuses would obviously not be necessary in order for the car to stay running)

what are some fuses i could pull?
the only fuses i would have to leave connected?
is this a bad idea to try in the first place?

Thanks in advance everyone

What makes you say the voltage is low?

my voltage on my dash reads 11-12 after the car is warm, 13 rarely, and only when the car is dead cold..... i've also checked the voltage at the battery, and its always the same as the dash reading
