MAINTENANCE
g) Check of residual voltage
For generators equipped with an electronic regulator, you must
perform the following procedure. This must be applied to ensure
that the generator is not over-excited (in such a condition, though
it still rotates at nominal velocity, no voltage is present in the
generator's main terminal board):
-) When the generator is switched off, remove lid from the
terminals case
-) Connect two connecting wires to a 12 Vdc battery with a 30Ω in-
series resistance
-) Follow the electrical diagrams supplied by Mecc Alte, to locate
positive and negative terminals of electronic regulator
-) Start generator
-) Connect, only for a moment, the two connecting wires to the
previously located terminals. Make sure to match polarities
(positive terminal of regulator with positive terminal of battery,
negative terminal of regulator with negative terminal of battery)
-) Use a voltmeter or the right instrument panel, to check whether
the generator is producing the nominal voltage indicated on the
plate.
