OK guys! here is the deal, here i will give u a picture of our setup.... battery to generator, to 4 tanks, to regulator, to single solonoid, to double solonoid, then to piston the piston is connected to our arm and we use the single solonoid to control how much it goes up and down, which works fine by the way , we can control it completly but thing is the arm is way to floppy i can put my finger on it and the arm will go down any suggestions??? or ideas on why this maybe happening?
