Hello. I am troubleshooting my amp meter and when I power it on, it shows "1 . " Anyone see that issue before?

I have double-checked my wiring and it appears to be right. I measured my input voltage to be 5.1V and the input it connected across the top and bottom of the shunt. i have attached a picture of the back of my amp meter.

The meter may be damaged in such a way that the meter is unable to communicate with the shunt. The shunt may also be damaged, but unlikely as it's just a piece of metal that is cut to a precise resistance. The power supply may also be damaged.
Given our previous discussions through email that concluded that this is not a control panel kit we sold (someone put together a kit and claimed it was ours), it could be that some of the parts are incorrect too. So I can't confirm the parts.
You could try powering the volt meter using the transformer and power supply that is currently powering the amp meter (disconnected from the volt meter first). If the volt meter continues to work (I'm assuming it's working now) then you know that the transformer and power supply are ok, and that likely the meter is bad. Note that if the power supply was at all damaged then this could also damage the amp meter.
Last but not least, sometimes people do not strip wiring or crimp correctly such that there is no continuity between parts. Or there could be a break in the wire from mishandling. None of these I can tell from the picture unfortunately. You can use a multimeter set to low ohms and hold one end against one of the connection holes on the meter and the other to the shunt screw. Ensure it shows as a short.
To properly set up the meters step by step, see:

Unfortunately given the nature of this kit it's hard to be specific as I don't know the other parts that are used as none of this is ours. Some careful sleuthing and replacing parts that do not appear to work right should get it sorted out.
Good luck!

I know...i am so upset that it isn't yours! Just so angry...oh well, power through it. I will do a continuity check, as I did have to splice wires together to extend the length to the shunt. If that looks good, i will then try the volt meter (it is working). Thank you for your help.

So i found an issue...there was no continuity on one of the wires that I had to spiced...i crimped it and must have missed the copper. So i replaced it with a single wire hoping that would be the silver bullet....now the Amp Meter doesn't even power up at all!!!! hahahaha....if it isn't one thing...lol

Got it all working. Just needed to ensure that all the wires had a solid connection to the meter. Thank you for the help.
