Please can someone tell me how to repair this voltage meter

[DKW]

i bought a volt meter panel https://www.ebay.com/p/DC-100v-10a-...lt-Amp-Meter-Gauge/595280927?iid=222595229103
and i gave 10v on thin wires and i accidentally shorted the thick red wire with the thin red wire. it smoked.

I need it for my school project and i cant aford a new one with my pocket money! pls help!!

It will cost more to fix than it would to purchase a new one.
