Have you got a multimeter Rico?
A visual inspection of the solder joint is not sufficient in this instance if you are having problems. Set your multimeter to the resistance mode and check for low impedance across each coil. ?The measurement should be equal to that of the meter leads shorted together. My preference is to check on the coil side of the circuit board on the plated through holes where the coil wires pass through. This avoids the possibility of touching a bare wire end, that has not been properly soldered. ?Checking carefully means actually taking measurements in my opinion. Due to the large areas of ground plane acting as a heatsink, more care and attention than on other boards you may have soldered is required. 73 Nick G0OQK
