Yessss Gary.. you legend., that’s exatly what I wanted cheers man..
iv ordered something similar that I found on eBay but I much prefer that one for its volt free output. Think the one I found used the 5v from the BAC just on or off so really thanks for that.. Iv spent my night butchering an old ripsaw. Attached a 2kg dumbbell to it and span it up to measure startup and run current and times etc. In a safe way obviously. Lol. Fun times haha
