If A Converter Fuse Blows; Troubleshooting - Schumacher Electric XI41B Owner's Manual

4. The case temperature becomes hot (exceeds 145°F). The Green and Red
LEDs are on, with a buzzer.
Allow the converter to cool. Do not block the cooling slots or air flow
over and through the converter. Reduce the load on the converter to the
continuous rated output.
RESET
To reset after shutdown occurs:
1. Disconnect the converter from the 12V power source.
2. Check the source of the problem and correct.
3. Reconnect the converter to the 12V power source.
NOTE: If the red LED is lit and the green LED is not, see the Troubleshooting
section.
Your power converter is fitted with two fuses, which should not have to be
replaced under normal operating conditions. A blown fuse is usually caused by
reverse polarity or a short circuit within the device or equipment being operated.
If a fuse does blow:
1. Disconnect the device or equipment immediately.
2. Find the source of the problem and repair it.
3. Install a new fuse (25A). The fuse can be found on the back of the converter.
IMPORTANT: Do not install a fuse with a higher amp rating than the original fuse,
as this may damage the converter and any product you use with the converter.
Make sure to correct the cause of the blown fuse before using the converter again.
