(Please take care to have your multimeter set to the right position: AC for the white leads, DC for the battery voltages.)
Under load the voltage on the white wires can be below 12V. Because the voltages from all 3 wires are added up (in some kind, it's a star configuration, similar to your electric oven at home). So that's not a worry in general.
Sounds to me as your RR is okay.
Also keep in mind that your battery is partly drained after each start. If the current from the RR is primarily needed to replace the charge in the battery who might get a low reading near 12V. It takes several minutes (maybe 5 .. 10 minutes, depending on battery conditon and revs) to reach steady conditions again.
