So, in the big scheme of things, when someone tells me they have it all worked out and a working system, I tend to believe them. This is the second time but I realise it is my fault, don't believe anything until you have tried it yourself. This is for a retrieval system, a small trolley runs up and down a stainless guide wire and is pulled back and forth by a simple 12 volt motor, a Johnson 600 Electric Drill Motor Now so far so good, have a real beefy power supply, structure is good, strong and everything installed. Turn the "Low Voltage DC PWM Motor " controller up, press the switch and it all stalls. Give it a bit of a shove and off it goes. Two things I think wrong with the system, the wires supplying the voltage ae "femme" and need to be heavier guage and the controller is just not up to it. I welcome suggestions please.
