The connector has three wires: the violet and brown wire, which go to the HEI module, and a black wire that will go to ground. The instructions for connecting the black and violet wires should be provided by the HEI distributor. If you don’t have any instructions, you’ll need to figure it out on your own. Once you have the connector, plug it in and turn it on.
You should see a green light come on, indicating that the module is ready to be used. Once you see that light, it’s time to turn on the power. To do this, press and hold the “Power” button for a few seconds, then release it. This will turn the light on and let you know that you’re now connected to a power source. Now, let’s take a look at what’s going on under the hood.

Do you need a coil with an HEI distributor?
all—HEI systems have the ignition coil mounted in the distributor cap. A control module and magnetic pickup are mounted in the distributor, in place of a conventional ignition system’s breaker box. HEI system also includes an electronic ignition control unit (EICU) that controls the timing of the spark plugs.
The timing is controlled by a timing belt, which is connected to the engine’s crankshaft via a belt-driven pulley. When the belt is in motion, it moves the camshaft, and when it is stopped, the pulleys move the valves. This system is similar to that used in a traditional engine, but with a few key differences.
Instead, a spark-plug igniter (SPI) is used to ignite the fuel. As the flame burns, oxygen is released from the air, causing the piston to move back and forth. At the same time, air is being drawn in through the intake manifold, creating a vacuum that propels the pistons forward.
Does HEI distributor need ballast resistor?
No ballast resistor is used or required with HEI. The output voltage to the plugs will be lower with the possible result of a misfire, because you are only lowering the voltage to the HEI. The power supply needs to be removed from the ballast Resistor.
If you do not want to use the battery charger, you can use a 12V DC power source to charge the batteries. This is not recommended as it will increase the risk of damage to your battery.
What are the two wires on a distributor?
A distributor with a pertronix will have two wires, red to coil positive along with switched power, black to coil negative. The wires should be long enough to reach the coil, and short enough that they won’t interfere with each other.
If you are using a Presto, you will need to connect the red wire to the positive terminal of the power supply, the black wire (the negative terminal) to ground. This is done by soldering a short piece of wire between the negative and positive terminals.
If you do not have a wire soldered between these two terminals, then you can use a jumper wire, which will allow you to use the same wire for both positive and negative, but it will be a little more difficult to solder the two together.
You will also have to make sure that the wire is not shorted to anything else, such as a fuse or a circuit breaker, as this will cause the circuit to short out.
How many volts does a stock HEI put?
If you want to run it on higher voltages, you will need to add a fuse to the fuse box. You can do this by cutting a small hole in the bottom of the box and inserting a piece of wire into the hole.
This will allow you to plug in a 12 volt battery. If you are using a battery that is not rated for 12 volts, make sure that the battery is fully charged before plugging it in.
How do you set a vacuum advance HEI?
You can easily adjust the vacuum advance of the Street Fire Distributor. Insert a 3/32″ Allen wrench in the canister inlet and turn the adjustment screw clockwise until it is all the way in (Figure 2). The advance is reduced by counter clockwise and increased by counter clockwise. If you are using a vacuum pump, you will need to adjust it as well.
To do this, insert a 1/4″ socket wrench into the pump outlet and rotate it counter-clockwise. This will allow you to tighten the hose clamping screw. If you do not have a wrench, use a small flathead screwdriver to loosen the screw and then tighten it back to its original position. Do not over tighten, as this will cause the valve to over-pressurize and blow out the fire extinguisher.
You may also want to check to make sure that the nozzle is not blocked by a piece of hose or other obstructions. The nozzle can be adjusted by loosening the two screws that hold it in place, then tightening them back down to their original positions.
Where should the distributor rotor point at TDC?
The number 1 position on the distributor cap should be pointed out by the rotor button when the number 1 is at the top dead center. The rotor should not be pointed at any other position. If it is pointing at a position other than 1, it may be a bad rotor. If you have a rotor that is not working properly, you can check it with a rotary tool. Rotary tools are available at most auto parts stores.
You can also check your rotor with an oscilloscope. A good way to do this is to put a small amount of oil on a piece of paper and hold it up to a light source. When the light goes off, the oil is no longer in contact with the paper. This is a good indicator that your rotors are not functioning properly.
How many amps does an HEI ignition use?
An hei draws 2- to 3-amps, compared to an external oil-filled coil draw of 6-amps. A much cooler running engine results from the lower amperage draw. HEI coils are available in several sizes, from 1/4-inch to 1-1/2-inches in diameter, and from 0.5 to 2.0 inches in length. They can be installed in the engine’s crankshaft, connecting rod, or intake manifold, depending on the application.
What sends spark to the distributor?
The distributor has a shaft that the rotor is connected to. As the rotor spins, it makes contact with a number of points and sends the spark through that point to the plug wire. The spark is then sent to a spark plug, which in turn ignites the fuel in the cylinder. This friction causes the pistons to move up and down.
If the friction is too great, the cylinders will not move at all, and you will have a flat engine. In order to prevent this from happening, you need to make sure that your spark plugs are not too close to each other. You can do this by putting a piece of tape on the end of each plug to keep them from touching, or you can use a rubber band to hold them in place.
