Coil
The coil provided is used with an external ballast resistor,
which is designed to control the internal temperature of the
coil windings. The resistor cannot be repaired in any way,
and if defective, must be replaced.
If the coil primary wires are removed from the terminals, be
sure they are installed on the same terminals when replaced.
If these wires are reversed, a reverse polarity situation
occurs inside the coil which can decrease coil efficiency and
life, and upset engine performance.
See wiring diagram for further details.
Battery and Battery Cable Installation
1. Battery should be positioned as close to engine as
possible and should be securely mounted in boat.
2. Connect negative (-) battery cable to ground on engine.
3. Connect positive (+) battery cable to solenoid.
4. Connect positive (+) battery cable to positive (+) post
on battery and negative battery cable to negative (-) post
on battery.
CAUTION: Engine electrical system is negative
ground. Failure to connect battery leads, as
outlined, will damage system.
Battery Maintenance
WARNING: Hydrogen and oxygen gases are
produced during normal battery operation or
charging. Sparks or flame can cause this
mixture to ignite and explode, if they are brought
near the vent openings. Sulphuric acid in battery
can cause serious burns, if spilled on skin or in
eyes. Flush or wash away immediately with clear
water.
Check battery with a hydrometer. If reading is below 1.230
(specific gravity), recharge or replace the present battery.
We recommend the use of a 12-volt marine battery with a 70
ampere-hour or larger capacity. Inspect battery and cables
for signs of corrosion on battery, cables and surrounding
area, loose or broken battery box, cracked or bulged cases,
dirt and acid, electrolyte leakage and low electrolyte level.
Fill cells to proper level with distilled water.
The top of the battery should be clean and the battery box
and/or hold-down bolts properly tightened. Particular care
should be taken so that the top of the battery is kept clean of
acid film and dirt to prevent a short between the battery
terminals. For best results, wash first with a dilute ammonia
or soda solution to neutralize any acid present and then flush
off with clean water. Care must be taken to keep vent plugs
tight so that the neutralizing solution does not enter the cell.
To ensure good contact, the battery cables should be tight on
the battery posts. If the battery posts or cable terminals are
corroded, the cables should be cleaned separately with a
soda solution and wire brush. After cleaning and before
installing clamps, apply a thin coating of petroleum to the
posts and cable clamps to help retard corrosion. If the battery
has remained undercharged, the local servicing dealer should
check for loose alternator belt, defective alternator, high
resistance in the charging circuit or a low voltage output.
The Charging System
Features a marine approved alternator with slip rings and
brushes sealed in an ignition proofed metal case at the rear
of the alternator. Two brushes carry current thru 2 slip rings
to the rotor field coil. Stator windings are assembled on a
laminated core which forms part of the frame. A rectifier
plate connected to the stator contains 3 positive and one
isolation diode. Three negative diodes which are pressed into
the end frame are also connected to the stator windings.
These diodes change the A.C. current produced by the
alternator to D.C. current and directs it to the alternator out-
put terminal. Field current is supplied and controlled by the
voltage regulator which senses the alternator out-put from
the Aux. terminal of the alternator. The alternator requites no
maintenance because of the sealed type bearings used on the
rotor which eliminates the need for periodic maintenance.
The solid state voltage regulator is non-adjustable. If the
regulator proves defective, it must be replaced.
Provision is made in the charging circuit for the installation
of a charge warning light, if it is desired.
Alternators and regulators should be serviced only by
qualified personnel.
Charging System Maintenance
CAUTION: Since alternator is designed for only
one polarity system, following precautions
must be observed when working on charging
circuit. Failure to observe these precautions
will result in serious damage to electrical
equipment.
