General Motors (Delcotron) Except Delcotron 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 regulated or
external sensing.
Motorola Load Handler Series or 8EM Remote Sensing Series.
GROUP
1
A Group 1 Isolator will have an alternator post and up to four battery posts. There are no colored
terminals.
General Motors (Delcotron) Equipped with Delcotron CS Series (most 1985-1993) or
CS130-D Series alternators (most 1993 and newer).
Jeep Vehicles equipped with Delcotron 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.
Ford Many 1998 and newer.

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 holes 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 CS Series alternators require a separate sense wire (not included).
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.
Motorola Other than Load Handler Series.
Bosch Requiring regulator sensing.
GROUP

Battery Isolators are not compatible with these alternators: A Battery Separator is recommended
for these applications. Alternators with internal voltage sensing, i.e., some Mitsubishi and
Hitachi, or single wire self-exciting Delco alternators. Isolators may be used if the alternator is
modified.
