Hi everyone,

I accidentally connected my charger with reversed polarity. After realizing the mistake, I disconnected it and reconnected it correctly. Now it shows 14.2V, but 0A output.

Could there be an internal fuse or protection component that might have blown due to the wrong polarity?

Any advice or troubleshooting tips would be greatly appreciated!

Thanks in advance!

Have you checked the fuse under the cover next to the output connections?

No im on vacation and unfortunately dont have the tools to test the fuse, but is it possible that the fuse might have burned?

Flip the end cover off, pull the fuse, you can see if it’s blown or not.
