Class Discussion Item 2.1
Proper Car Jump Start
Schematic of a Proper Car Jump
Proper Cable Connection Attach red cable to
positive post of the good and dead battery
Attach black cable
to Negative post of running car
Proper Cable Connection Do not attach
remaining black cable to negative post of dead car
Instead:Attach to a clean,
unpainted spot on the engine or frame away from the dead battery
Why This Works Manufactures wire the frame and
engine directly to to negative terminal
Thus, completing the electric circuit
Why?
Recharging causes water in the dead battery to split into Hydrogen and Oxygen
2H20(l)
2H2(g) + 02(g)
Removing the Cables
In reverse order: Negative cable from engine Negative cable from good battery Positive cable from dead battery Positive cable from good battery
Safety
Make sure cars are not touching Never allow jumper cable claps to
touch while any clamps are attached to battery
Keep engine in good car running Be sure to connect Positive to
Positive and Vice versa
