What is the firing order on the distributor cap?
The firing order on a distributor cap for an 8 cylinder engine is 1 2 3 4 5 6 7 8. Inside the distributor cap is the rotor. The rotor strangely enough got that name because it rotates. As it rotates it passes a spark though to each of the spark plug wires that are plugged into the top of the distributor cap.
How do you find the #1 cylinder?
on an inline engine: the number one cylinder is located at the front of the engine, closest to the timing cover. on a v type engine: one cylinder head is slightly forward of the other, toward the front of the engine. cylinder number one is the forward most cylinder in that bank.
How do I know if my distributor has a firing order?
The firing order starts at the distributor's number one terminal and continues in clockwise or counterclockwise fashion until reaching the number one terminal again.
What wires go to an HEI distributor?
Connect the primary wires to the HEI distributor, via a plug that snaps into the distributor cap. There are two wires in the plug: the hot wire and the tachometer wire. If you are updating from an old distributor, splice the old distributor hot wire to the hot wire of the HEI primary plug.
Does HEI distributor need a ground wire?
When you have an external coil (hei), ground wire in cap is not needed.
How do you test a HEI distributor?
Use a volt meter to test the hot wire while a buddy cranks the engine over. If the voltage drops below 10.5, check your battery. If the battery is fine, make sure the wire feeding the distributor is sufficient.
How do HEI distributors work?
The HEI distributor is an inductive-discharge-style ignition, but with the points replaced by a solid-state switching device called an electronic ignition-control module. The module works like an electrical switch, turning power on and off to the ignition coil. This, in turn, causes the coil to generate spark.
