The voltage regulator type is identified by terminal contacts and based on the information set out
in Appendices 1, 2. There is only one terminal – LIN, which identifies this voltage regulator as COM
type.
Consult Appendix 1 to determine which clips (connectors) of the diagnostic cable must be
connected to the voltage regulator. The diagram of voltage regulator ARE6149P connection to the
tester is shown in both Table 4 and Figure 24.

Connection of voltage regulator ARE6149P has a specific feature. We connect cable F1 to the only
terminal – F. As the actual voltage regulator is B-circuit type, the other cable (F2) must be
connected to terminal B-. Consequently, one of the brushes is permanently connected to B- of
the alternator, while the excitation winding is controlled through terminal B+.
