Where is the tachometer wire located?

The tachometer will have wires coming from the back of the gauge. One is a ground wire, one is a power supply sire, and one connects the vehicles ignition system either via the ignition coil or through an electronic connection with the vehicles computerized ignition.

Is a tachometer a speed sensor?

Tachometers and Speed Transmitters require a permanently mounted speed sensors that observe a target on the machines rotating shaft. While Keyways generally create a once per turn pulse speed gears may produce 10, 30, 60 or 100 pulses (teeth) per revolution.

How do you test a RPM signal wire?

Start the vehicle and wait for it to idle down to normal idle speed. At this point the meter should be displaying a fairly constant AC voltage. If this is the case, rev the motor up and down and observe the reading on the meter. The AC voltage should rise when the engine RPMs rise and fall when the engine RPMs fall.

How many volts should my ignition coil have?

Electricity Goes Out The average vehicle ignition coil puts out 20,000 to 30,000 volts, and coils used in racing applications are capable of 50,000 or more volts at a constant rate. This new voltage is then routed to the distributor via the coil wire, which is just like the spark plug wires, only normally much shorter.

Are HEI distributors better?

An HEI distributor is a great piece of equipment for an over-the-road car because it is completely self-contained. But without an external coil, a stock HEI cannot provide a strong spark at rpm levels commonly seen on the racetrack. Engines with higher compression or more horsepower also require a hotter spark.
