Yes,he did say he had only the central bit of the test to do. He did say there was a bit of water on the connector on the ignition board when he removed it so could be why it kept blowing the fuse on the main pcb until the water moved away but now the fuse doesnt low and fan just kicks in recycling slow and fast. He's put his gas meter on the gas valve somewhere and said the gas not opened up and there's no spark also.
