Operation

Troubleshooting

The unit will operate whenever power is connected. The ON led will be illuminated whenever 

power is connected to the charger. The OVERLOAD led will be illuminated whenever the 

output current reaches the maximum.

If the ON led is not illuminated, check with a voltmeter for voltage between the IN + and IN - 

connections. If there is power, check to make sure the connections are not reversed. Positive 

should be on the outer terminal (terminal 1). If the connections are correct and the ON led still 

is not illuminated, the input fuse may be blown. Remove the cover by unscrewing the four 

cover screws under the base and lift it off. Be careful not to lose the two light pipes for the 

leds. With the input and output disconnected, check the fuse with a good ammeter. If the fuse 

is good, then the unit is damaged and must be returned for repair. If the fuse is blown, then 

contact your dealer to have it replaced.
