MODEL #2304A EXTRA.H EAVY-D UTY ON/O FF
Battery Switch
EASY INSTALLATION
Guest' Extra-Heavy Duty On/Off Switch is a single pole, singlethrow switch with alternator field circuit disconnect for use where high
amperage is required, such as diesel engine starting. Raied at 600 amps continuous, '1000 amps momentary, the switch is5112"
square and 3 1/2" high.
Warning: lt is important that cold start amperage requirements of your engine do not exceed the rated capacity
of this switch.
The switch features:
1 . Alternator field disconnect, which interrupts the alternator-field when switch is turned 1o 'loff' position, thus preventing electric
surges in the armature circuit which might burn out the alternator diodes.
Positive click stop in all positions, with large easyto-read dial.
Rugged polycarbonate case with built-in skirt to protect electrical connections. Can be panel or flush mounted.
Heavy-duty copper contacts.
For use with 6, 12, 24, and 32 volt systems.
lnstallation lnstructions
Mounting
Switch should be located as close to the batteries as possible with regards to convenience of operation. The battery and starter
cable should be as short as possible.
There are three mounting positions:
1. Surface mounting with the wires going through the openings at the base of the switch.
2. Surface mounted with a hole in the mounting surface to permit wires to come through at the back of the switch.
3. Recessed mounting of the switch through a hole in the mounting surface.
For surface mounting, place the switch in the desired location and, using the switch as a template, locate the four mounting
holes. Then drill four equally-spaced #12 holes on 4 3/8" centers.
For Lecessed mount[g, pla_ce the switch in the desired locatiQn,_and using the switch as_a templatg,_lo.cate lhq c54!q1 Cut_a

washers may be used on the mounting bolts between the switch flange and the mounting surface to adjust the portion of the
switch that comes through the hole.
Wiring
1. The battery switch is designed to accept up to 4/0 cable. The battery cable should be sized in accordance with the engine
manufaciurer's recommendations. Other guides to wire sizes may be obtained from The American Boat and Yacht Council's
Electrical StandardsEll. Terminal lugsshouldbesizedtoaccommodatethesizeofthewireandtheterminal bolts.
The brass terminal bolts of the battery switch are %" in diameter
2. Wire for alternator field circuit disconnect switch should be #14 with terminal lugs on the ends.
(See wiring diagrams for suggested installations).
Recommended Mounting of Cables at Switch
Connect cable (A) fronr positive post of battery #1
to switch terminal #1 .
Connect cable (B) from positive post of batlery #2
to switch terminal #2.
Connect cable (C) from starter solenoid and cable
(D) from accessory (load) to Feeder terminal on
switch.
See "Wiring" for cable and terminal requirements.

SUGGESTED WIRING DIAGRAM FOR ALTERNATOR FIELD DISCONNECT CIRCUIT
Alternators with EXTERNAL REGULATOR:
Remove regulator field wire (regulator "F" terminal) and connect to new wire leading to Guest'battery switch field terminal (either
terminal). Add another wire from other switch field terminal and connect to regulator "F" terminal. Use #14 wire for new circuit.
Carefully tape connections for proper insulation.
OR
lf it is easier to reach the alternator, remove alternator field wire (alternator "F" terminal) and connect to new wire leading to Guest'
battery switch field terminal (either terminal). Add another wire from other switch terminal and install to alternator "F" terminal. Use #14
''vire for new circuit. Carefully tape connections for proper insulation. OR

Alternators with INTERNAL REGULATOR:
The field circuit wire on alternators with iniernal regulators is located within the alternator housing and it is impractical to use the field
disconnectfeature. Protectlon of the alternatordiodes can be achieved by installing a Guest'lsolator #2401A(for70 ampere
alternators) or other appropriate model.
See below for various wiring diagram for alternators with internal regulator:

Caution: This product is designed for use
under normal condrtions. lf switch is used to

SWITCH SHOULD BE REPLACED to avoid
possible future failure.
