BREAKERLESS DISTRIBUTORS
INSTALLATION INSTRUCTIONS
AND TECHNICAL INFORMATION
FORM A1454 (REV. F) 04/03
GENERAL INFORMATION
ACCEL 71000 Series distributors feature a magnetic triggering
device with an adjustable mechanical advance as well as a totally
independent adjustable vacuum advance.The electronic module is
designed for use with 12-volt negative ground systems only.
Accel 71000 distributors are smog legal for specific applications.
Contact the factory for applications that have been granted
C.A.R.B. exemptions.
ACCEL 71000 distributors utilize an internal module and therefore
do not require an external ignition box. However,71000 series
distributors are compatible with most ignition amplifier boxes
(including those from ACCEL and Mallory) if a hotter spark is
required.
Cap
71000 series distributors are supplied with a standard clip-on cap
with traditional female spark plug wire receptors.
A screw-down cap with male spark plug type posts is available.
The kit (PN 8345) includes the cap, a special rotor and mounting
hardware.
Spark Plug Wires
Do not use solid metal core spark plug wires. Suppression type
plug wires must be used (carbon core or spiral core). Solid core
wires will cause false triggering and eventual module failure.
Coils
When installing your new distributor, it is important to check the
primary resistance of the coil.To do this,use an ohmmeter and
with the ignition switch off, check across the + and – terminals of
the coil.The resistance value should be less than 1 ohm. If the
resistance is greater than 1 ohm, you have a coil which was
designed for a factory points style distributor.Using a coil which
was designed for a points style ignition will cause the electronic
module to overheat and fail.ACCEL recommends using a coil
designed for an electronic breakerless ignition system which,
ideally,has a primary resistance of less than 1 ohm.ACCEL part
numbers 140001, 140008, 8145, or 8145C will work exceptionally
well. Please note that an ACCEL 71000 Series Distributors should
never be run with a CD Coil, without the use of a CD Control Box.
NOTE: Failure to use a coil with the proper primary resistance
(less than 1 ohm) will void your warranty.
Reluctor to Pickup Gap
The gap should be checked when installing the distributor for the
first time.The gap should be as small as possible without rubbing.
The gap must be .010” to .020". If starting problems occur, make
sure that the gap is still less than .020".
Distributor Gear
ACCEL 71000 series distributors include a steel gear which is
compatible with most flat tappet cams, as well as factory type
hydraulic roller cams.
Some 71000 series distributors do not include a gear. If your
application requires a gear,instructions are included on how to
install your stock gear onto the ACCEL distributor.
Welding
Disconnect the distributor wire harness before welding on the
vehicle.
Mechanical Advance
The mechanical advance is factory set to provide 24° (crank)
advance all in by 3000 RPM.This is a good general purpose curve
and will work for most applications.
NOTE: Check local smog laws before changing the advance
curve. Advance adjustments should only be made by qualified
personnel with the proper test equipment.
To gain access to the mechanical advance, remove the cap, rotor,
reluctor, vacuum advance chamber and the pickup plate.The
reluctor can be pulled off the rotor sleeve using a small gear
puller. Do not lose the small roll pin that drives the reluctor.The
vacuum advance chamber is held in place with two screws and
an e-clip.The pickup plate is held in place by two small set
screws in the side of the distributor housing. See the enclosed
instruction sheet for instructions on advance adjustment.
Vacuum Advance
The vacuum advance operates independently from the mechanical
advance.The vacuum chamber is factory adjusted to produce 10°
advance (crank) at 10" of vacuum.The vacuum advance can be
adjusted by inserting a 3/32" allen wrench into the hose nipple on
the vacuum chamber. Turn the wrench clockwise to increase
advance, counterclockwise to decrease. See Figure 1.
NOTE: Check local smog laws before adjusting the vacuum
advance.
In most cases, the vacuum advance hose should be connected
to a ported vacuum outlet on the carburetor. This is the same
location as stock. However,in some cases where a very large
camshaft is used, connecting the vacuum hose to full manifold
vacuum (near the bottom of the carb) will improve idle.
Vacuum Advance Lockout
If the vacuum advance is not going to be used (such as for
racing), the vacuum advance chamber can be removed and
replaced with the enclosed lockout.The lockout covers the hole
in the distributor housing and prevents the pickup plate from
rotating.

ACCEL cap in the same order and relative locations. Install the
ACCEL distributor so that the rotor points to the same plug wire as
the previous distributor. This should make the timing close enough
to start the engine.
Wiring
See Figure 2
DO NOT USE A BALLAST RESISTOR! Some older vehicles used a
resistor wire to power the coil.This must be bypassed. Using a voltmeter, verify 12 volts to coil positive (+) when the key is in the RUN
position as well as START.When bypassing resistor wire or running
a new SUPPLY wire, use at least 14 gauge from coil positive (+) to
the starter solenoid or a switched terminal in the fuse box.
Remove the vacuum chamber by removing the two screws and
the e-clip.Place the lockout on the distributor.Be sure that the
hole in the lockout is over the pin on the pickup plate. Secure the
lockout with the e-clip and the two screws.
NOTE: Check local smog laws before removing the vacuum
advance chamber.
Installation
Installing a 71000 series distributor and setting the timing is done
in much the same way as a stock distributor (see a repair manual
for more information). If another distributor is already installed
(and correctly timed) note the direction the rotor is pointing
before removing the distributor. Transfer the plug wires to the
Connecting to ACCEL 300+ Ignition
Or other CDI box, ignition amplifier, or multiple strike unit.
Your new distributor is designed as a stand-alone unit. It does not
require an external ignition/enhancer box to operate.To use the
ACCEL 300+ (or other) ignition system with this distributor, the
electronic module must be bypassed.
Step 1
Remove the cap and rotor
Step 2
The electronic module is the green, half-circle shaped piece
with four wires attached to it. Remove the four wire leads (two
red, two green) from the module. They are attached with spade
connectors.
The module may be removed from the distributor, if desired.
Step 3
Connect the two leads from the magnetic pickup directly to the
ACCEL 300+. Connect the green lead from the magnetic pickup
to the ACCEL 300+ purple lead (magnetic pickup positive +).
Connect the red wire from the magnetic pickup to the ACCEL
300+ orange lead (magnetic pickup negative –).
Step 4
Other 300+ connections:
Red 12 volts key (ignition)
Black Engine Ground
Yellow 300+ Coil Positive (+)
Brown 300+ Coil Negative (–)
Step 5
Check magnetic pick-up for proper air gap. Using a non-ma gnetic
feeler gauge, set the gap to .010” to .020" maximum (see Figure 2).
Step 6
Follow instructions in the ACCEL 300+ booklet regarding spark
plug gap and ignition timing under "Technical Tips and Hints"
section.
