Can my car be short circuited?

I took off the positive side of the car battery and I was trying to turn it on but forgot that it was off. Clicking to turn it onIy then realized and replaced it back to the battery. When I did that I noticed that my dash instrument cluster went freaky.
Nothing is reading as it should. Like gas or the temp. Not even my speedometer works. Now noticing not even the lights in the cluster works.

The only reason why I haven t took off the negative is cause it was fastened down and couldn t gotten it moved.

Can anyone tell me what may have happen and how to fix?

Thanks for reading

It s a 1993 Honda Accord EX
