The voltage regulator fits to both circuits with and without battery
charging light; in the latter case connections LE (SAPRISA) and L
(DUCATI) are not used.
The voltage regulator shown in the picture is LOMBARDINI-DUCATI.
Connections for LOMBARDINI-DUCATI voltage regulator
How to check voltage regulator for proper operation
Check that connections correspond to the layout.
Disconnect the terminal from the battery positive poie.
Connect a d.c. voltmeter between the two battery poles.
Fit an ammeter between the positive pole and the corresponding
cable 1 terminal.
The ammeter should be suitabie for reading the required value (14
or 21 A) and for withstanding the starting motor peak absorption (400
÷450 A).
Start a couple of times until battery voltage drops below 13 V.
When battery voltage reaches 14.5 V the ammeter current suddeniy
drops down to almost zero.
Replace regulator if recharge current is zero with voltage below 14 V.
Warning: When the engine is running do not disconnect battery
cables or remove the key from the control panel.
Keep regulator away from heat sources since temperatures above
75°C mmght damage it.
No electric welding on engíne or application.
