1. Install rectifier-regulator assembly in location
determined by customer, using hardware and
torque specified by customer.
2. Remove shipping spacers from both sides of
rectifier-regulator.
3. Connect rectifier-regulator to alternator
with wiring conduit shown in
Figure 3 and 4.
4. Output conduit supplied by customer
connects rectifier-regulator with
customer circuit and consists of
B+ and B– output leads plus
R terminal lead if used.
5. R circuit current: 3 A max
Square wave signal: 0-30 V
Alternator speed formula: RPM=f(Hz)•10
6. Alternator is configured for self-
energization. Regulator brown wire
is connected to R circuit. If external
energize is required, remove brown
wire between R terminal and module
terminal A. Connect energize signal,
which must open when alternator shaft
is not rotating.
