Testing voltage regulator for proper operation
Checkthatconnectionscorrespondtotheschematic.
Disconnecttheterminalfromthebatterypositivepole.
Connectad.c.voltmeterbetweenthebatterypoles.
FitanammeterbetweenthepositivepoleandtheB+onvoltagere-
gulator.
Startandstop theengineaseveraltimesuntilbatteryvoltagedrops
below13V.
Whenbatteryvoltagereaches14.5Vtheammetercurrentshouldsud-
denlydropdowntoalmostzero.
Replace regulator if recharge current is zero with voltage below
12,5V.
Whentheengineisrunningdonotdisconnectbatterycablesor
switchkeyto"off"position.
Keepregulatorawayfromheatsourcesabove75°C.
Donoelectricweldingonengineorapplication.
