PLEASE READ INSTRUCTIONS COMPLETELY PRIOR TO STARTING INSTALLATION 4 3 2 1 GROUP GROUP GROUP GROUP General Motors (Delcotron/Delphi) Except Delcotron/Delphi CS series alternators (CS series used on most 1985 and newer GM vehicles). Ford Up to 1998 Chrysler All models, all years including Nippondenso externally regulated alternators. Jeep Equipped with Nippondenso externally regulated alternators Japanese Imports With alternators using external voltage regulator or external sensing. Motorola Load Handler Series or 8EM Remote Sense Series General Motors (Delcotron/Delphi) Equipped with Delcotron/Delphi CS series (most 1985 – 1993) or CS130-D series alternators (most 1993 and newer***) Jeep Vehicles equipped with Delcotron/Delphi CS series alternator (most 1985-1990). Toyota, Honda & Some Imports 1985 and newer equipped with Nippondenso alternator with internal regulators or alternators with an “S” (sense) terminal. Motorola Other than Load Handler Series Bosch Requiring regulator sensing A Group 3 Isolator will have a colored fourth terminal indicating the “R” terminal. Unplugging the plug-in connector from the alternator and counting the number of holes in the connector can identify the CS series alternator. The CS series will have three small and one large hole. The CS130-D alternator has four pin terminals all the same size. The SI series will have two slotted holes in the connector. ***Delco/Delphi CS series alternators require a separate sense wire which is included with the connector kit. The connector kit may or may not be included with the Isolator, but is available as an accessory. All Group 2 Isolators may be used in Group 1 applications. Simply disregard the additional excitation (“E”) terminal. A Group 2 Isolator will have a colored fourth terminal indicating the “E” terminal. Battery Isolators are not compatible with these alternators. A Battery Separator is recommended for these applications. Alternators with internal voltage sensing, e. g. some Mitsubishi and Hitachi , or single wire self exciting Delco/Delphi alternators. Isolators may be used if the alternator is modified.
