L1 TO RED
YELLOW TO RED
Resistance between L1 and A must be same as between A and yellow.
Yellow to red (winding side of switch) must be same as
L1 to same red terminal.
WINDING CONTINUITY
(For typical single phase, dual voltage only, capaci-
tor start, single speed motor, connected for 230V.
Set meter to R x 1).
For single voltage motors, check between L1 and
L2.
Slip a heavy piece of paper between points, taking
care not to bend tabs. Discharge capacitor by short-
ing across the terminals with the blade of an insu-
lated screwdriver. Take the following ohm readings.
