Hi, I bought this item on Amazon and just got around to installing on my project. I planned to use it to step down voltage from a 52V ebike battery for use with 12V accessories and USB. I connected the red/black pigtails on the input side, tested output with a multimeter, and it only shows 0.28 volts?

Could the black/ground wires being in the wrong position on the module cause this? Input from battery tested @ 56V.

Thanks

JC

Hello JC MCGUIRK,

Is it this item? https://www.amazon.com/dp/B018WZYBTA/ref=as_li_tl?tag=proeng-20

Did you check output under no load? If possible, would you like to show us the connection by images?

We will find solution for you once confirm the problem.

Best regards.

Hello,

It is the 20 Amp version of the one in your link: https://www.amazon.com/gp/product/B081RPH2Z2/ref=ox_sc_saved_title_1?smid=AFHAE9RJVUMB&psc=1

I tested it with no load and a 12V light that draws about 2 Amps. Both times the output was 0.28 Volts. Please tell me how to send a picture of my connections

Thank You!
