D+ - Diode trio output. Alternator requires external excitation.    
REG - Regulator Terminal. Alternator requires external excitation.    
I - Ignition Terminal. Alternator can be externally excited through this terminal.    
IG - Ignition Terminal. System voltage must be supplied to this terminal to turn on the alternator. Some of these alternators use the IG terminal as a sense terminal.     Often when problems with the charging system are being investigated, the alternator is not the problem. If a low battery condition is present test the batteries first. See Special Instruction, SEHS7633, "Battery Test Procedure" for more information. If the engine cranks slowly, then test the starting system. See Service Magazine, SEPD0020, "Testing The Starter On The Engine" for more information. If a
