J88 OWNER MANUAL 41

Leave the craft unattended with the electrical system energized, except automatic bilge-pump, fire protection
and alarm circuits.
DC Electrical System
A 12 Volt DC electrical system is used throughout the J/88 for lighting and operation of pumps and various
accessories. The J/88 is standard with one 90 Amp Group 27 Glass Mat battery located aft of the starboard
settee berth. One additional optional battery may be added within this area.

Electrical Panel: controls electric distribution with circuit breakers and switches. The main wiring
harness runs from the back of this panel.

Mast Wiring Terminal Box: is located in the head area on the main bulkhead. A wiring harness
exits the mast and leads forward on the underside of the deck to this junction box after the mast is
stepped. The junction box is wired directly into the DC system through a terminal strip. Once the
mast wiring is installed and mated at the junction box, be sure to test each function to insure proper
operation.

Battery Switch: The battery switch is located in the backrest storage bin of the starboard settee
backrest.

The 80 amp Yanmar alternator is attached to the engine and creates a charging current for the
battery system when the engine is running.

Accessories: such as navigation instruments, stereo, GPS, etc… can be added to the electrical panel
and the 12V DC system. Extreme care and forethought is necessary for installation as these are
sensitive instruments and require some measure of protection. We recommend that owners hire a
qualified marine electrician to complete these tasks. Be sure all sensitive accessories are not only
grounded properly but that proper fuses are run off the panel.

Optional 110 VAC Shore power System
The optional 110 Volt AC shore power system is functional only when the boat is plugged into suitable power
from shore. The cord provided as part of the option has the standard end for 30 amperage service. Ensure
the plug prongs match those on the dock inlet, insert and twist to lock it. Then screw down the outer ring to
seal the cord from water and to prevent it from pulling out. The AC panel for shore power is located in the
navigation station next to the primary DC panel.

AC Main Power Switch : Located on the panel, to activate AC power panel, use this switch.

AC Panel: indicates line voltage being received from the shore circuit with an indicator light. The
line voltage will vary with the number of appliances operating on the same circuit. In large marinas
there may be a large number of boats on the same circuit, causing fluctuations.

AC Normal/AC Reverse Polarity Light : The AC panel has a red light to show when the polarity is
reversed. Care should be taken not to operate 110 AC systems on board with reversed polarity.
Double-check shore connections. If problems still persist, then notify dock master to repair the shore
plug. NOTE- Even though the switches are in the appropriate position, the shore power system in
no way assures personal safety using electrical apparatus.
