- It all Adds Up
well as the headlights will demand about 25 to 30
amps from your alternator.
• Next, bring the engine speed up just above normal idle—
about 1200 RPM.
• Allow a minute for the system to stabilize; then measure
the voltage across the poles of the vehicle battery. You
should see at least 13.6 V. Many charging systems will
operate at a higher voltage but should not exceed 14.6 V.
If your system falls within this range, it is probably function-
ing well. If not, it will need further diagnosis and repair. Note
that one of the most common reasons for a low output from
the charging system is a worn or improperly tensioned alter-
nator drive belt.
If your charging system is functioning, and you are a typical
radio user, you will be able to operate the 500-watt system
without any modification to the charging system. In special
instances, where the transmitter operates for extended key-
down periods, it may be necessary to install a special, high
capacity alternator. (Remember that the current require-
ments for an SG-2000 driving the SG-500 can exceed 100
amps—four times that required to run automobile accessories.
At 10.0 VDC, the amplifier will drop off-line due to under-
voltage. The auxiliary battery maintains the required current
needed to power the 500 watt system.)
Isolating the Auxiliary Battery
Our suggested installation of the 500 Watt system and addi-
tional auxiliary battery, along with a “smart” solenoid, will
not only insure enough power for a whopping signal from
your radio system but will provide for a “jump start” capabil-
ity just in case your main battery becomes discharged.
The solenoid requires connections only to the main battery,
auxiliary battery, starter switch, and ground. It will work
