WARNING
If connections are inverted the regulator will be irreversibly damaged.
Check that the regulator earth connections are efficient. Possible checks to be carried out on the
alternator or regulator if the battery fails to re-charge or the power supply is no longer regulated.
Alternator
With the engine switched off, disconnect the two yellow generator cables from the rest of the system and then
carry out the following tests with a ohmmeter:
Check the winding isolation towards earth
Connect one connecting point of the ohmmeter to one of the two yellow cables and the other connecting point
to earth (laminar pack).
The instrument should indicate a value above 10 M
Check the winding continuity
Connect the two connecting points of the ohmmeter to the two yellow cables.
The instrument should indicate a value of 0.2÷0.3 .
Check the voltage output
Connect an alternate 200 Volt capacity voltmeter to the two yellow cables.
Start the motor and check that the voltage output is included within the values indicated on the following tables:
r.p.m. 1000
A.C. volts 15
Regulator
The regulator has been calibrated in order to maintain the battery voltage at a value between 14÷14.6 Volts.
The pilot light (illuminated when the engine is not running, but the key is inserted) will switch off when the generator
begins to charge, (approx. 700 r.p.m.)
Regulator checks
Normal work-shop tools are generally insufficient for regulator checking, however, listed below are certain
operations that can be carried out in order to detect regulators that are defective.
The regulator is certainly defective if:
After having isolated it from the rest of the system short circuits can be detected between the earth (aluminum
casing) and any of the output cables.
