The recommended / described use of electrolytic capacitors
for replacing an AC motor start capacitor is a SERIES connection
so the effective capacitance is HALF (unless the reverse biased
side acts as a short on each half cycle...then the effective capacitance
would be equal to the marked value...anybody know?).
