INSTALLATION

1. Install pulley of your choice and use the pulley nut supplied. (Discard pul-

ley nut spacer.)

2. Install with quality brackets and bolts.

3. Use care when tightening belt. Do not over tighten belt. Allow 1/2" belt

deflection.

4. Attach battery (+) cable to alternator B+ output post. Reattach ground wire

to the battery.

5. Start engine and apply a moderate load (30 amps approx.) to charging sys-

tem. With a digital voltmeter set for DC volts and with one test lead on the

grounding bolt at the "adjusting ear" and the other test lead on a good ground-

ing point on the engine block, measure to see if you have DC volts present.

If you have a reading of 0.10VDC or higher, you have a poor ground con-

nection between alternator and engine block. Recheck your alternator

grounding points at the "foot" or "adjusting ear". (See Figure 3).

INSTALLATION INSTRUCTIONS

Racing Alternator

Notice: This unit has been built for racing applications. Therefore certain precautions and installation

procedures should be followed closely. If you are installing the alternator w/pulley end toward

the driver (i.e., supercharger application) be sure to use an alternator designed for CCW cooling.

PRE-INSTALLATION CHECKS

1. Always use a new or a known fully charged racing battery (12.7-13.0 volts DC). 80-90% of all

alternator failures are due to weak or defective batteries.

2. This racing alternator has a black thermal coating which has insulating properties electrically.

Care should be taken to insure a good ground at the "foot" of the alternator and "adjusting ear"

to the engine block. (See Figure 1).

3. Make sure battery ground (-) is disconnected to prevent sparks or arcing during installation.

4. Carefully check all electrical connections at alternator and battery. Check ground cables and

connections. Look for broken or frayed wires and use dielectric grease when making final

battery and alternator connections. This keeps oxides from forming and aids electrical contact.

To check ground voltage drop, set DVM to DC

Volts and read voltage between alternator foot

bracket or adjusting ear and battery ground (-)

terminal. Voltage should be less than 0.10VDC. A

higher reading indicates a poor ground.

Use only welding type cable (i.e., multi-strand, highly

flexible wire) and heavy duty crimps and adhesive

sealing heat shrink tubing (See Figure 2).

5. Use care in handling the alternator. Do not drop it, hammer on the case, pry against

the case to tighten the belt, etc. The rotor and stator are built to very close tolerances

and this could cause internal rubbing and subsequent failure.
