3. If capacitor is good, pointer will deflect, indicating
capacitor is being charged, followed by a
deflection in the opposite direction indicating
partial discharge.
If there is no deflection, capacitor is "open" and
must be replaced. Also, if meter needle moves and
stops at one value, replace capacitor.
Replacement capacitors must be ordered from
factory. When ordering, supply serial number of
charger and microfarad (MFD) or (µF) value printed
on capacitor.
