7.26 Alternative Capacitor Check

See Graphic: wc_gr001607 and wc_gr001783
An alternative capacitor check is to set the multimeter to the 10,000
Ohm scale when checking the capacitor. Observe the reading. If the
reading starts out very low (5.0 Ohms) and continues to climb to an
overload or open reading, the capacitor may be OK. Double check by
installing the capacitor in a known-to-be-working Light Tower. If the
known-to-be-working Light Tower operates correctly, the capacitor is
OK. A second alternative check would be to try a known-to-be-working
capacitor in the original Light Tower. If the Light Tower still does not
produce power, the problem is within the generator. Check the stator
and rotor.
