Good, I have a lawnmower Yard Garden Machine that starts and the seconds stops and tries to start again. I measured the 20uF capacitor and it gave me 7uF so I assumed that was the problem and I went to buy another one. The original is 20uF x 500v and the one they gave me is 18uF x 450v, I would like to know if that 50v difference could affect anything ...
