How to test if a capacitor is good if my DMM farad's range is less than the capacitor's
If your meter's limit is 100 uF then you could measure the 470 uF by putting it in series with a 100 uF. The net capacitance should be: -

$$\dfrac{1}{\frac{1}{100uF}+\frac{1}{470uF}} = 82.46 uF$$

And this should be in the range of your meter (providing it can measure electrolytic capacitors correctly). Of course, many electrolytic capacitors can be up to 80% higher than their marked value so what you really need is a good reference point for capacitance; maybe use two 100 uF capacitors in series and see what that gives you as a reference. It should be 50 uF but could be as high as 90 uF.
