Mechanic's Quick Reference
==========================


"FOOL PRESSURE CHART"

(For those who refuse to use a pressure gauge)

Due to the fact that most technicians do not want to take the time to
correctly test the fuel pressure, we have developed the following...

With the engine running, either push the schrader valve in or loosen the
fuel line THEN IF:

Fuel does not come
out of the test area...                     Pressure is approx 0 psi

Fuel hits the hood insulation...            Pressure is 5 - 8 psi

Fuel squirts over the fender...             Pressure is 10-15 psi

Fuel splashes off the
fender onto the hood insulation
and into the next repair bay...             Pressure is 25-30 psi

Fuel squirts to the garage roof,
all over the car,including
the shop owner...                           Pressure is 30-50 psi


VACUUM TEST
"Rule of Thumb"

Put thumb on vacuum hose leading to direct engine vacuum.

Don't feel anything                         Change thumbs and re-test

Still don't feel anything                   Vacuum is very low to none.

Hose has slight suction                     1" to 5"

Suction causes skin to wrinkle              5" to 8"

Suction turns thumb blue                    8" to 10"

Suction creates hickey on thumb            10" to 12"

Suction creates pain                       18" to 20"

Suction will not release
and begins to move toward
index finger                               20" to 25"


"IDIO-ILLUMINATION" CHART

With the vehicle prepped and ready to be tested, hook the negative lead
of the test light to a good ground and proceed with testing.

                                           The voltage is
The bulb DOES NOT light                     0 - 1 volt

The bulb MIGHT be glowing                   1 - 3 volts

The bulb BARELY GLOWS (or there is a
reflection from the overhead lights)        3 - 5 volts

The bulb GLOWS MUCH BRIGHTER than #2,
but only a little brighter than #3          5 - 7 volts

The bulb GLOWS WITH THE SAME INTENSITY
AS A BALD HEAD ON A SUNNY DAY               7 - 9 volts

The bulb GLOWS BRIGHTLY and is
GAINING IN INTENSITY                        9 - 11 volts

The bulb is ALMOST BRIGHT
ENOUGH TO READ BY                          11 - 13 volts

The bulb is BRIGHT ENOUGH that you
still see a spot when you look away        13 - 15 volts

The bulb SHINES WITH THE INTENSITY
OF A HALOGEN HEADLAMP                      15 - 17 volts

The bulb is so bright that it
MAY BE A SIGN FROM GOD                     17 - 19 volts

The bulb flashed with the INTENSITY
OF A MINOLTA FLASH POINTED 3 FEET
FROM YOUR FACE                             20 to 40,000 volts
                                         (Secondary Ignition)


IGNITION VOLTAGE OUTPUT TEST

Scopes may be inaccessible from time to time, so we at "Bubba's Garage"
have come up with this here test for Ignition Output:

1.Hold medium wrench in one hand, Sears wrench preferred for accuracy of
test 'cause other smooth wrenches are too slick for throwin'!

2.With engine runnin', grab hold of the plug end of an ignition cable
with the other hand and hold on tight!

3.This will more than likely cause you to throw wrench!  KV output is
based on how far the wrench wuz thrown!

       10 feet =                 approx. 10,000 volts
       20 feet =                 approx. 15,000 volts
       30 feet =                 approx. 25,000 volts
       Over 30 feet =            Caution!  Must be
                     one of them new dis-is-it ignition systems,
                     use bigger wrench and retest.

WARNING! No side effects have been reported due to testing at this time
(although it has been known to kill chiggers after berry pickin')

Bubba Sez: Electricity will not usually hurt you, instead it is the back
of your neck going through the hood latch that really ruins your day!!

HOW TO TORQUE WITH AN IMPACT WRENCH.

Yes you can use your impact gun to torque nuts and bolts if you use this
handy chart along with your ears and a quick trigger finger.

TORQUE VALUE         INGERSOLL IMPACT            SNAP-ON IMPACT

25 to 35 ft/lbs   BAP!                          BAP!
35 to 45 ft/lbs   BAP! BAP!                     BAP! BAP!
