52000 SERIES MAGNETIC

BREAKERLESS DISTRIBUTORS

INSTALLATION INSTRUCTIONS

AND TECHNICAL INFORMATION

FORM 1638 (REV. B) 10/04

GENERAL INFORMATION

ACCEL 52000 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 52000 distributors are smog legal for specific applications.

Contact the factory for applications that have been granted

C.A.R.B. exemptions.

ACCEL 52000 distributors utilize an internal module and therefore

do not require an external ignition box. However, the ACCEL 52000

series distributors are compatible with most ignition amplifier

boxes (including those from ACCEL and Mallory) if a hotter spark

is required.

Distributor Cap

ACCEL 52000 distributors are supplied with a male tower clip-on

cap with HEI style spark plug wire connections and a wire retainer

ring. If a more tradition style female tower distributor cap style is

desired or required, then the ACCEL 52000 distributors can be

fitted with an ACCEL tan cap and rotor kit p/n 8120. Please note

that when changing to the traditional style female tower cap, that

it is required that you change BOTH the cap (p/n 120124) and the

rotor (p/n 130117). If a black female cap and rotor kit is desired,

then use ACCEL p/n 8124.

Spark Plug Wires

Do NOT use solid metal core spark plug wires. Suppression type

spark plug wires must be used (either carbon/graphite core or

magnetic suppression spiral core). Solid core spark plug wires will

cause false triggering and eventual module failure.

Coils

When installing your new ACCEL 52000 distributor, it is important

to check the primary resistance of the coil. To do this, use an

ohmmeter. With the ignition switch off, check across both 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 that was designed for a factory points style distributor. Using

a coil that 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

coil part numbers 140001, 140008, 8145, or 8145C will work

exceptionally well with the ACCEL 52000 distributors. Please note

that an ACCEL 52000 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 Magnetic Pickup Air Gap

The reluctor to magnetic pick-up air gap is preset on the ACCEL

52000 Series Distributors for optimum performance and triggering

accuracy. It does not require any adjustment.

Distributor Drive Gear

ACCEL 52000 distributors are factory fitted with a steel alloy drive

gear that is compatible with most flat tappet cams, as well as

most factory type hydraulic roller cams. Some ACCEL 52000

distributors do not include a drive gear. If your application requires

a drive gear, instructions are included on how to install your stock

drive gear onto the ACCEL 52000 distributor.

If you are using a factory hydraulic roller camshaft, we suggest

that you check for gear wear after the first 100 miles. If you are

using an aftermarket roller camshaft, you may need to use a

bronze distributor gear. Check with your camshaft supplier for

additional information.

Welding

Disconnect the ACCEL 52000 distributor wire harness before

welding on the vehicle.

Mechanical Advance

The ACCEL 52000 distributors are factory set to provide

approximately 20° degree (crank) of mechanical advance, starting

at about 900 RPM all in by about 2100 RPM. This is a good

general-purpose curve and will work for most applications. If you

engine has a higher static compression ratio or higher cylinder

pressure from a super or turbo charger, or is used in a heavily

loaded application such as a two vehicle or is equipped with

racing type components, then the mechanical advance curve may

need to be custom tailored to the your particular engines needs.

NOTE: Check local smog laws before changing the advance

curve.

Selecting and Changing the Mechanical Advance

The cams, springs, stop bushings and weights all determine the

mechanical advance curve. The starting point, amount and rate of

the mechanical advance are adjustable. When the mechanical

advance starts is controlled by the tension of the springs and their
