This is not a battery charger, this is a battery KILLER, so fuck me this shit in recycling.

First it would be good to review these connections a bit, um ...

Then check if the fuses you have replaced are “T” (time delay).
Check if the “boost” position also blows the fuse.
Then it would be well to take measurements to see if there is a short circuit, internal or external to the transformer (but I fear that ...)

I say that, I say nothing ... there is a lot of video on youtube to know how to investigate.

Finally, considering its invoice, is it worth repairing it? Yes if it's for fun.

Here are some technical tips for basic precautions:

But your charger does not seem equipped to control either the current or the charging voltage.
So it's potentially a battery killer.
