CEN N1617
Alternator Description and Operation
N1617 570 A 28 V alternator is internally rectified.
All windings and current-transmitting components are
non-moving, so there are no brushes or slip rings to
wear out. Energize switch activates regulator. Field coil
is then energized. Alternator output current is self-limit-
ing and will not exceed rated capacity of alternator.
N3264 remote-mounted regulator used with these units:
• regulates alternator voltage so that neither Battery A
signal nor Battery B signal exceeds 30.0 volts.
• is negative temperature compensated according
to switch-selected vehicle battery type. Switch is
factory-set to position 1. Customer selects position
per application
—Position 1 for Gel, AGM
—Position 2 for 6TLFP, 6TLMF

B– connections on alternator
Both ground cables must be connected to vehicle’s common
ground. An interconnect cable is required as shown if a single
cable to vehicle common ground is used.
Both positive cables must be connected together at alternator or
isolator input when alternator is installed in vehicle and during
operation. Interconnect cable is part of vehicle cabling.
