the output clamp from the battery 

post.

9.  Clean and store the charger in a dry 

location.

system: Connect the red (POSITIVE) 

output clamp to the POSITIVE post of 

the battery. Rock and twist the clamp 

back and forth to be sure a solid 

electrical connection is made. Then 

connect the black (NEGATIVE) output 

clamp to a heavy, unpainted metal 

part of the chassis or engine block, 

away from the battery (see figure). 

DO NOT connect clamp to negative 

battery post, carburetor, fuel line or 

sheet metal part.

 

system: Connect the black (NEGA-

TIVE) output clamp to the NEGATIVE 

post of the battery. Rock and twist 

the clamp back and forth to be sure 

a solid electrical connection is made. 

Then connect the red (POSITIVE) 

output clamp to a heavy, unpainted 

metal part of the chassis or engine 

block, away from the battery. DO NOT 

connect clamp to positive battery 

post, carburetor, fuel line or sheet 

metal part.

6.  Plug power cord into a 120V AC  

2-prong wall outlet. The charger will 

be set to the default state of REGU-

LAR battery type, no charge rate 

(tester mode). The CONNECTED 

LED should be lit. If the CONNECTED 

LED is not lit, check for correct cable 

connections.

NEGATIVE (NEG, N or -). The positive 

post is usually larger than the negative 

post.

2. Attach at least a 24-inch-long, 6-gauge 

(AWG),  insulated  battery  cable  to 

NEGATIVE (NEG, N or -) battery post. 

Rock and twist the clamp back and forth 

to be sure a solid electrical connection

3. Connect  the  red  (POSITIVE)  output 

clamp to the POSITIVE battery post. 

Rock and twist the clamp back and forth 

to be sure a solid electrical connection 

is made.

4.  Position yourself as far away from the 

battery as possible, and then connect 

the black (NEGATIVE) output clamp to 

the free end of the cable.

5. Plug  the  power  cord  into  a  120V  AC  

2-prong wall outlet. The charger will be set 

to the default state of REGULAR battery 

type, no charge rate (tester mode). The 

CONNECTED LED should be lit. If the
