The two transformers were wired to the same Hot/Neutral/Ground so either one was bad or it needed to be rated for 240v?
Ok, I'm got the AMP meter wired to it's original power supply and after jumping around a bit when I initially turned the on switch it's settled into between 3.3-3.5 amps normal?
My guess is that the hot transformer torched both the dc power supply & the volt meter. Plausible?
This is my first wiring job outside of electrical outlets
Hmm...I'm on the train right now, so I'm not in a position to figure out the schematic. It's certainly possible that the wire is too small for the job, though it should be fine if it really is just on the low-voltage/logic side of your circuit.
3.3-3.5 is a degree of fluctuation that I'd be more comfortable with, but still might indicate that one of your components is dead or dying. Again, I don't know what kind of power conditioning this is supposed to have, nor what kinds of power draws you have, so it's hard to say much of use. Powering on will often cause some initial jumping around. As long as you don't have sensitive components in there it is okay.
A hot transformer could certainly equate to a dead dc power supply and volt meter. More specifically, either the transformer was over capacity and started turning out more current than it should have, or the same thing that was over-powering the transformer ended up over-powering the volt meter and power supply.
Sorry I'm not much help here. Really all I'm saying here is that I agree something is wrong, based only on general electrical principles. I hope somebody else familiar with the build will jump in. In the meantime, you might want to consider rebuilding your circuit step-by-step to see if you can find your point of failure. Good luck!
