Hello,
I borrowed a multimeter from someone so I could use it to measure the voltage stored in the capacitor bank. I don't want to blow it up, so how would I go about measuring the capacitor voltage while it's charging?
I'm guessing it's just +ve to +ve and -ve and -ve. Should I just wire it like this ?

Well that link you gave is for measuring capacitance, which you should already know since its printed on you capacitors (hopefully). For measuring the voltage your bank is charged to, yes you would put the meter in parallel with the capacitors (thats black probe to -, red to +).

Remember not to fiddle with the meter if connected to a charged bank. You may switch it to current mode or some mode that ends up forming a short across the LOAD!
Practice on a $10 meter. Practice using the meter over batteries first. Insert a high wattage low value resistor in series with the probe lead then intentionally put the meter in current mode across a battery. When you feel the heat and possible some smoke based on the battery supply and the chosen current limiting resistor, know that this is but a fraction of what will happen if you mess around with high voltage capacitors lacking full knowledge of how to measure and deal with them.
