Broken multimeter digital ammeter

Hello everyone. The device became unusable, it can be seen from old age and I decided to make a digital ammeter out of it. He removed the insides, left only the holes for the probes. The battery for the device is from the navigator. The digital device itself is sold for a mere penny. It can measure voltage, but I left only an ammeter. I turned on the toggle switch into the finished hole on the left. The device measures the current up to 10 amperes.

repair a multimeter (with which I measured the current strength on a car battery. some 500 amperes)

If the device works at other limits and splashes of metal from the shunt did not damage anything, then replace the shunt and the resistors connected to it.

Can there be any fuse?

In the 830s, there is usually a fuse in the low current circuit, in a 10-20 A circuit there is no fuse.

It is not clear what the author did. Is the Chinese ammeter stuffed into a multimeter?
It would be better to tell how a glitchy multimeter (with which I measured the current strength on a car battery. Some 500 amperes) was repaired or made into an ammeter.

that is not such a thing. I got it like that. Probably burned. Can there be any fuse?
