How to build a $20 47A power supply

[BrianG]

I assume all the red wires are 24v and the blues are ground? If so, then loosely judging by the number (8?) and gauge of the wires, I'd say each wire is good for ~2A, which is around 16A, maybe a bit more.

What you could do is monitor the output with a voltmeter while steadily loading down the supply with resistors or something until it shuts down from over-current. Then a little math to figure out the shut-down current, and then subtract ~10% as the "working" current.

There are 11 red 24v wires ranging from 18-22gauge wire. I thought I saw a video that had a charger showing the operating amperage? Maybe that was the amperage that the user set the charger to draw.

Thanks for the idea on the resistors I'm just afraid of "frying" the supply doing that. Is that a possibility?
