1.4 Alternator Specifications

Alternator Specification
Alternator model
Stator leads, qty.
Phase
Rotor resistance, ohms, cold
Stator resistance, ohms,* cold
Main winding: 1-2, 3-4
Aux. winding: 55-66
Stator output voltage with separately excited rotor using 12-volt battery, minimum
Main winding: 1-2, 3-4, volts
Aux. winding: 55-66, volts
Rotor field voltage/current readings at rated output voltage, hot
No load, volts/amps
Full load, volts/amps
* Most ohmmeters do not give accurate readings when measuring less than 1 ohm. The stator can be considered good if a low resistance
reading (continuity) is obtained and there is no evidence of shorted windings (discoloration). Do not confuse a low resistance reading with
a reading indicating a shorted winding.
