Alternators - DELCO-REMY With Integral Regulator: Description
The Delcotron 10 SI alternator with integral regulator is used on all American Motors models except the Eagle equipped with heated rear window and fog lights. It is available with rated outputs of 42 and 55 amps. On General Motors vehicles, 10 SI, 15 SI, and 27 SI alternators are used. The 10 SI alternator is available with different idle outputs and maximum outputs of 37, 42, 55, 61, and 63 amps. See Figure. The 15 SI alternator offers a maximum output of 70 amps., while the 27 SI alternators offer maximum outputs of 80 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.
