That’s because tight and secure wiring connections are important to ensure smooth current and power flow. Secondly, you must check all the wiring connections. While you are checking for the open inline fuse, make sure there are no open wires between the battery and converter as well. So, check the inline fuse and make sure it’s closed. However, in some cases, the inline fuses open up accidentally, which stops the connections between the battery and the converter, resulting in charging issues. The inline fuse is responsible for protecting the circuit of the battery in case of overcharging – it opens up to end the connection. If the power converter is connected to the battery but the battery is not charging, the first step is to check the inline fuse in the battery wire.

So, when you have to install a new fuse, reconnect the battery properly and make sure the new fuse has the same amp rating. The fuse usually blows out when the battery is connected in reverse form, either at the converter or at the battery. If there is no continuity, it means that the fuses are blown and you have to get them replaced.

On the other hand, if there are no physical damages, you can use the multimeter to check for continuity. If the fuses are damaged, they should be replaced to ensure there are no hindrances in the current flow. If there is no DC power output, you’ve to inspect the reverse polarity fuses, which are installed on the back of the converter. WFCO 55 AMP Power Converter Troubleshooting So, we are sharing some common problems as well as the troubleshooting guide. However, the power converter also has some errors that you must know about. In addition, it promises noiseless operation and its DC connections are fully insulated.

WFCO is a well-known brand of power converters and the 55 AMP power converter is a three-stage converter that not only manages the charging needs of the RV but also extends the battery’s lifespan by preventing overcharging (overcharging causes damage to the battery).
