Dual voltage alternator, simultaneous outputs of 28 Volt / 14 Volt, 100 Amps.
C.E. Niehoff Co. model N1506-1. Military P/N 12420852. NSN 6115014194033.
This alternator is used on the M1078 series.
Alternator is brushless design (no brushes and no slip rings to wear out).
Integral N3030 dual voltage regulator.
Rated output of 100 amps is maximum combined total current between the two outputs.
Upper voltage output (28V) is rectified with standard
diodes. Lower voltage output (14V) is controlled by SCRs in the drive end housing.
Alternator output current is self-limiting and will not exceed rated capacity of alternator.
F- terminal (used optionally on some vehicles).
One wire energize power (24 volt) input to regulator. All input and output connections via terminal studs.
Can replace N1509-1 (12422863) and N1511-1 alternators, however, N1506-1 is not compatible with the N2003 Load & Battery Control. If the N2003 is used on the vehicle do not use N1506-1. Consult service literature for details on model differences.
