7.1 Jump-Starting Direct to the Battery
With the Jump-Start Cables supplied, Portable Power 250 may
be used to jump-start a vehicle or boat that has a 12-volt
starting battery. Portable Power 250 has a special jump-start
safety feature that eliminates the sparking that sometimes
occurs when jump-start cables are connected to a battery.
Because of this important feature, the instructions below are
different from those often supplied with other jump-start
products or booster cables. Follow these steps only when
using Portable Power 250:
1. Turn off the vehicle or boat ignition, and all accessories.
2. Engage the park or emergency brake and place the
transmission in park or neutral.
3. If jump-starting a boat engine, purge the engine
compartment and bilge of all fumes before jump-starting.
4. Connect the Jump-Start Cables to the Jumper Cable Port
on the left side of the unit. (See Figure 1.)
5. Position Portable Power 250 on a flat stable surface near
the battery and clear of all moving parts of the engine.
6. Connect the red positive (+) clip at the end of the Jump-
Start Cables to the positive (+) terminal of the engine
battery. The battery’s positive terminal is usually larger
in diameter than the negative terminal. In most vehicles it
has a red wire connected to it.
7. Connect the black negative (-) clip at the end of the Jump-
Start Cables to the engine block, cylinder head, or other
stationary heavy metal part of the motor, or to the
negative (-) battery terminal.
8. If the positive and negative clips are properly connected,
the green Battery Clips Correct light will illuminate. If the
clips are not properly connected the Reverse Polarity
Alarm will sound and the red Battery Clips Incorrect light
will illuminate. Remove both clips to cancel the alarm and
repeat steps 6 and 7.
