.Connect the brown lead terminal to the other battery
( + ) terminal and connect the black/yellow lead terminal
to the battery ( -) terminal momentarily. At this time the

.To apply 24 V to the regulator/rectifier, connect two 12
V batteries in series, and connect the brown lead
terminal to the battery ( + ) terminal and the
black/yellow lead terminal to the battery ( -) terminal
momentarily. The bulb should now light and stay on
until the bulb circuit is opened.
Regulator Inspection
To test the regulator out of circuit, use three 12 V
batteries and a test light made from 12 V 3 -6 W bulb
in a socket with leads.
.Remove the regulator/rectifier unit from the frame.
.Using auxiliary leads, connect one of the yellow lead
terminal at the unit to the battery ( + ) terminal, and
connect the test light between the black/yellow lead
terminal at the unit. and the battery ( -) terminal.
.At this time the bulb should not be lit.
