I need a max of 40v and 8a to power my drop down variable power supply. I have old microwave transformers so I removed the secondary and rewound it with 14 gauge wire. I now get 48vac and when I use a bridge rectifier it brings it down to 40vdc. I tried to test amps by hooking up my tester (rated at 20amps) and only succeeded in burning up some jumper wires luckily no other damage.
I don't have a clamp on tester and can't afford to buy one.
How can I determine the amperage, and if too high bring it down to my target?
Thanks
