it means 470 resistor and is used in many circuit boards.
The drain plugs on a 470 MerCruiser engine typically use a 1/2-inch NPT (National Pipe Thread) size. It's essential to ensure that the plugs are properly sealed and in good condition to prevent leaks. Always refer to the specific maintenance manual for your engine model for the most accurate information.
The heater resistor coil is located on the blower motor on the 2006 T300 Kenworth.
Resistors are color coded to denote the value of the resistor as well as the multiplier. In your case a 470 ohm would be colored as Yellow Violet Brown corresponding to 4, 7 and a multiplier of 10^1.
helpful hint coil resistor condenser is usually located on the intake manifold or general proximity.
The MerCruiser 470 engine typically uses a point gap of 0.018 to 0.020 inches for the ignition points. It's important to check and adjust the gap periodically to ensure optimal engine performance and prevent misfiring. Always refer to the specific service manual for your model for the most accurate specifications. Proper maintenance of the ignition system is crucial for reliable operation.
A: That resistor is there to limit the current to the LED it can be any value if the voltage is decreased or increased or no resistor if the voltage across the led is equal to the forward voltage drop.
