i have a 1972 nova with a points distributor. I replaced it with an hei i had laying around. i opened up the spark plug gap from .035 to .045 to better utilize the increased voltage of the hei. i ran a wire directly from the battery to the hei(through a switch on the dash to turn on and off) as i knew that the points distributor wiring would limit the voltage(something about a resistor wire or ballast resistor) The problem i had was that the engine didnt idle well with the hei as it did with the points. however the hei ran better through the rpms(up to 6000rpm) so im still trying to research that problem Some motors will idle too fast/rough at manifold vacuum, in which case you will need to connect your vacuum advance to ported vacuum.
It is inside the distributor.
It is inside of the distributor.
The 327 cubic inch Chevrolet's distributor had points and condenser and not an ignition module. If you have an ignition module then you have a HEI distributor that was changed out.
Find your distributor cap and follow the center cable to a rectangular part. This is the ignition module. Remove it, get a new one and install it.
If you remove the distributor cap, you will see it bolted on the base plate
There is a problem in the distributor. Either the pickup coil or the ignition module are defective. It may be cheaper to purchase a remanufactured distributor.
The module is located behind the Rotor Arm assembly in the distributor itself. You have to remove the Distributor Cap, then the Rotor Arm and the module is there.
The pickup coil in the distributor? !976 should be an HEI distributor. Take the cap off, unplug the wires going to the distributor, remove the rotor and the pickup coil is under the rotor and held in place with two screws.
It could be either the crank angle sensor or the distributor module. If it is the distributor module, you have to buy and install a re-man distributor.
The spark control module on a 1989 Chevrolet model van is located in the distributor. To check its life, one must remove the distributor cap and unplug the center coil wire. Replace with a clean, brand new spark plug, and test the van's ignition.
get a testlight ground it to the battery and turn the switch on and check the hotwire coming out of the module Also if you can remove it from the distributor you can take it to a good auto parts store and they can bench test it for you.
The ignition module is located in the distributor, under the distributor cap.
