I connected board power 12v + and - wires that are fused for the marine radio and the LED lights up with some numbers.
The negative - power connection is the same as one of the current sense connections looking at back of board.
I thought the radio negative to battery might go to the current sense side, but no, the radio would not turn on, and when wired that way, it blew the 10 amp fuse for the battery.
When measuring ohms across the sense terminals, it read 2 million ohms whether powered on or not.
I dont understand how this is supposed to work.
Here is the device, can someone please tell me how to wire this up?
Or if its defective?
And is there some better board I can buy to measure DC current and flip a relay on and off?
