Quoted from Redcloud:All chimes work. The tens chime worked when connected to the 100s chime relay
ie he's got a short in the lead from the 10s relay to the chime box. told him to unsolder at the jones plug and you can determine if its in head wiring of bottom board wiring...
Next step inspect the pinch points. If its in the head wiring, easy enough to run a new lead and replace.
With it unsoldered and powered off you can measure resistance between the lead and the black wire return thats on ever coil
