Alternators - MOTORCRAFT: Description: Notes
Ford alternators are 12 volt negative ground units. Alternator amperage outputs range from 38 to 90 Amps. Alternators use six diodes, except the 61 Amp. alternator uses eight diodes. Alternators with 70 and 90 Amp. capacities are side terminal units. Alternator regulators are either electro-mechanical or transistorized.
CAUTION:
Before servicing alternator or regulator, note the following precautions to avoid component damage.
