TESTING CONTINUITY
Quick field check (no capacitance scale on meter).
Connect a digital ohm meter or analog ohm meter
(high scale) to the capacitor terminals. The meter will
register and arbitrary ohm value for the material in the
capacitor. the meter's battery will then start to charge the
capacitor and the ohm value will increase.
If the meter does not react as above, the capacitor is faulty.
The method above indicates a presumably good capacitor,
but does not verify it's rnicrofared rating as would be
necessary when troubleshooting a capacitor whose MF rating
has dropped causing a low AC voltage output. In such cases,
the capacitors rating
MUST
be verified accurately.
A
WARNING:
Capacitors must be discharged before
handling as they store electricity and can pack a poten·
tlally lethal charge even when disconnected from their
power source.

NOTE:
When changing a capacitor due to a capacitor failure,
reference the capacitor rating as printed on the body of the
capacitor and order the correct replacement. Installing a
capacitor of a higher MFD rating will result in highAC
output voltage and installing a capacitor of a lower MFD
rating will result in low AC output voltage.
