Alternators & Regulators - DELCO-REMY With Integral Regulator: Description
The Delco-Remy 10 SI and 15 SI Delcotron alternators with regulators are used on all American Motors models. Amperage variations of 41, 55, and 63 amps. are furnished by the 10 SI, and 70 amps. by the 15 SI model. See Fig 1 .
General Motors vehicles use the 10 SI alternator, available with different idle outputs and maximum outputs of 37, 42, 55, and 63 amps., as well as the 15 SI and 27 SI. The 15 SI alternator offers a maximum output of 70 amps., while the 27 SI alternator offers maximum outputs of 80, 85 and 100 amps. See Figure .
All models feature a solid state regulator mounted inside the alternator, providing electrical system protection, eliminating needless wiring, saving space and preventing misconnection of terminals.
The construction and operation of all models is basically the same. Delcotrons consist primarily of 2 end assemblies, rotor, stator, brushes, slip rings and diodes. The rotor is supported in the drive end frame by ball bearings and in the slip ring end frame by roller bearings. Bearings contain enough lubricant to eliminate need for periodic lubrication.
