SOLUTION

 

 

 

 

 

 

No meter reading.

Connections are reversed.

 

With charger unplugged, reverse clips and

 

 

 

 

reconnect (rock back and forth to bite in).

 

 

Poor electrical connection.

 

Clean clips and battery posts and reconnect

 

 

(roll back and forth to bite in).

 

 

 

 

AC outlet is dead.

 

Plug in a lamp or other appliance to check

 

 

 

 

for voltage.

 

 

Battery is defective (will not
