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.
Stalling of Vehicle. One ignition coil symptom that previews what occurs when the coil fails totally is a stalling engine. Engine failure will result when the coil totally fails. If the ignition coil is not working, the existing spark plug is uneven, which causes uneven firing of the pistons.
