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.
