If The Converter Fuse Blows; Troubleshooting - Schumacher Electric SI3 Manual Del Usuario

9. IF THE CONVERTER FUSE BLOWS

Your power converter is fitted with a fuse, 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 the 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 (40A). The fuse can be found on the right side of the
converter. NOTE: If you are using the 12V accessory plug to power the
converter, there is also a 15A fuse in the end of the plug.
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.
