Classic Gauge Functions

	Electronic Tachometer
	These precision units feature a full 270-degree sweep and are easily adjustable for 4, 6, or 8 cylinder operation. Our electronic tachometers are designed for good response and accurate readings with most standard point, electronic, GM-HEI, magneto, MSD, or other aftermarket ignition systems. The Classic Tachometer can be installed with our Tachometer Filter (included at no extra charge) properly wired to avoid the voltage spikes and surges that are so common with todays' vehicles and engine systems.



Marine Diesel Tachometer
We offer a tachometer for Diesel enthusiasts. The scale of 0-1200 RPM was designed especially for the marine diesel engines that operate at relatively low revs. This tachometer will connect directly to the alternator output of many diesel installations. Currently available only in the Vintage Series.

Fuel Gauges and Tank Senders
Classic Marine Fuel Gauges are compatible with other manufacturers' senders such as AutoMeter, LTL Industries, Maxima, Medallion, Stewart-Warner, Sun Electric, and others. They may also be ordered to read correctly with many OEM fuel senders. For reliable and accurate fuel level readings, order a matched Classic Fuel Sender with your fuel gauge. Fuel gauges from Classic Marine Instruments are available in most of the resistance ranges shown below. This greatly simplifies gauge-to-sender matching when a specific tank is used in the boat.

	Water Temperature Gauges
	Maintaining the correct coolant temperature is important to prolong the engine's performance and reliability. Accurate readings can provide advance warning of engine over-heating before a critical loss of coolant can occur. The sensitive pointer response on your Classic Temperature gauge movement will even indicate the opening and closing of the thermostat


Oil Pressure Gauges
The Oil Pressure instrument responds to changes or loss of pressure at the sender location. It reads in pounds of pressure per square inch (PSI). Sensitive movement even displays "surging" of the oil pump at idle speed. Use with Classic Oil Pressure Sending Unit. Volt Gauges The Volt Gauge measures the relative condition of the electrical system by the voltage level in the battery. Voltages outside the normal 12-16 volt range may affect the performance and the reliability of sensitive electronic components.


			Amp Gauges
			This gauge indicates direction and relative strength of current flow and also monitors the electrical output of alternator or generator. The 60+ to 60- amperes dial range covers normal sweep on these internally-shunted units. The gauge will also indicate if the boats electrical accessories are consuming more current than the alternator is outputting. Not for use in systems where alternator output will exceed 65 Amps.


Quartz Clocks
The clocks use the same bezels and lenses as our other small individual instruments. Order with any bezel finish, and with either curved or flat glass lens. The Electric Remote Reset switch provision eliminates the front-knob on the lens of the instrument. A Remote Reset Switch is available for the clocks. The clock drains very little current from the battery therefore allowing it to remain hooked to battery hot lead for several months without appreciable drain. Clock should not have to be disconnected during normal boat storage periods.
