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 ca-
ble 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.
Important
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 abo-
ve 75°C mmght damage it.
No electric welding on engíne or application.
