Integrated Microcircuit Regulator
The integrated microcircuit regulator is similar to that of a fully transistorized regulator, except it is much smaller. The microminiature electronic components are too small to be seen in detail with a microscope. These regulators are sealed and have no provisions for adjustment. If the regulator voltage reading is not within specifications, the regulator must be replaced.
These voltage regulators come in different sizes, shapes and mounting locations. Delco-Remy regulators are mounted in the alternator housing. Some Ford regulators are mounted on the outside of the alternator. Chrysler Corp. electronic regulators are mounted on the firewall in the engine compartment.
