Noah looked at the photograph of Earl taped inside the notebook's cover. "Neither do I," he said. "If you tell me the exact numbers, I can check what I have. I won't say I found something until I've verified it."
Daniel's tone changed slightly. He had been expecting an enthusiastic teenager to promise a quick fix without listening, and instead he was being asked for the same information that a parts specialist would request. He gave Noah the generator's basic identification, promised to send photographs from the data plate, and offered to put his regular technician on the phone. Noah wrote everything down, read the numbers back, and explained that he would need time to research.
The Mercer farm had been operating for more than thirty years. Daniel and his wife, Teresa, managed a herd whose milk went to a regional processor under quality standards that left little room for equipment failure. Their cooling system depended on stable electrical service, particularly in warm weather when milk had to be brought down to the required storage temperature promptly. The farm had a backup generator because a thunderstorm did not care whether a dairy's equipment was halfway through an important cycle.
Daniel had purchased the generator used several years earlier after a prolonged outage nearly caused him to lose a full tank of milk. The machine was old but carefully maintained, and until the drive component failed it had started whenever the farm needed it. His usual technician, Thomas Reddick, had already warned him not to force another start with the damaged assembly. Doing so could turn an isolated component failure into more serious damage.
Noah understood the stakes without needing Daniel to exaggerate them. Rachel's cooperative handled invoices from dairy farms, and he had heard enough anxious calls after summer outages to know that backup power was not an optional convenience. It protected both the product and the equipment needed to keep an operation running. An unreliable repair might work during a brief demonstration and fail during the very emergency the generator existed to handle.
He said as much to Rachel after he hung up. She listened while he explained the missing component, the uncertain availability, and the possibility that one of Earl's old engine families matched the generator. Then she asked what he planned to do first. Noah opened the inventory book and turned to the page for engine eleven.
"Check the numbers," he said. "Then check them again."
The email arrived within the hour. Daniel had taken clear pictures of the generator plate and the damaged component laid beside a measuring scale, and Thomas had added notes describing the relevant operating requirements. Noah printed the photographs at the library the next morning because his home printer had developed the habit of producing faded vertical stripes. He spread them beside Earl's notebook and began comparing the identification codes.
