There are five stable isotopes of nickel: Ni-58, Ni-60, Ni-61, Ni-62, and Ni-64. Properties: The melting point of nickel is 1453Â°C, boiling point is 2732Â°C, specific gravity is 8.902 (25Â°C), with a valence of 0, 1, 2, or 3. Nickel is a silvery white metal that takes a high polish. Nickel is hard, ductile, malleable, and ferromagnetic. It is a fair conductor of heat and electricity. Nickel is a member of the iron-cobalt group of metals (transition elements). Exposure to nickel metal and soluble compounds should not exceed 1 mg/M 3 (8 hour time weighted average for a 40 hour week).
No start condition. Another common symptom of a bad or failing ignition pickup is a vehicle that does not start. If the ignition pickup fails, it will not provide the signal necessary for the vehicleâs ignition system to operate, and as a result the engine will not start or run.
Overall, a weakâor lack ofâspark due to a bad wire, or another failed ignition component, has a negative effect on engine performance and mechanical components. Spark plug wires deliver thousands of volts (up to 50,000 or more) to the spark plugs. To carry such large voltages, plug wires need to have some basic physical characteristics. For example, thick insulation to prevent high voltage from jumping off the wire before it reaches the spark plug, and a rubber boot at each end to protect metal connectors from moisture, corrosion, oil, and other contaminants.
