Detlection Method:
Apply a force ol 98 N (1 0 ksl, 22 lbl) and measure the
deflection between the alternator and the crankshaft
DUllev,
Defloction: 9- 11 mm (O.35-O.43 inl
NOTE: On a brand-new belt (one that has been run
for less than five minutes), the deflection should be
81881, Bl8Cl engine: 6 - 8 mm (0.23 - 0.32 inl,
818C5 engine: 7 - I mm (0.28 - 0.35 in) when first
measured, lf the belt is worn or damaged, replace it.

CRANKSHAFT PULLEY ALTERNATOR BELT
lf adiustment is necessary:
1. Loosen the alternator adjusting nut and mounting
nut.
2.
3.
Move the alternator to obtain the proper belt tension,
then retighten the adiusting nut and mounting nut
to the specified torques.
Recheck the dellection of the belt.
NOTE: lI necessary, adjust the P/S pump belt (see
section 17) and A/C compressor belt (see section
221.
Belt Tension Gauge Method:
Following the gauge manulacturer's instructions, attach
the belt tension gauge to the belt and measure the
tension.
Tension: 340-490 N {35-50 kgf,77-11O lbf)
NOTE: On a brand-new belt (one that has been run
for less than five minutes), tension should be
818B1, 818C1 engine: 690 - 880 N (70 - 90 kgf, 154 -
198 lbf), 818C5 engine: 540 - 740 N (55 - 75 kgf,
121 - 165 lbf) when first measured. lf the belt is
worn or damaged, replace it.
lf adiustment is necessary:
1. Loosen the alternator adjusting nut and mounting
nut.
2.
3.
Move the alternator to obtain the proper belt tension,
then retighten the adjusting nut and mounting nut

Recheck the tension ot the belt.
NOTE: It necessary, adjust the P/S pump belt (see

Power Distribution schematics show how power is supplied from the positive battery terminal to
various circuits in the car. Refer to the Power Distribution section to get a more detailed picture
of how power is supplied to the circuit you're working on.
From Battery to lgnition Switch, Fuses, and Relays
lndividual circuit schematics begin with a fuse. The first half of Power Distribution, however,
shows the wiring "upstream" between the battery and the f uses.

How To Use This Manual
Test Equipment
lf, in addition, you need to know exactly how
much resistance there is between two ooints.
use a digital volVohmmeter (DVOM).
In the "oHMS" range, the DVOM will show
resistance between two points along a circuit.
Low resistance means good continuity.
Diodes and solid-state devices in a circuit can
make a DVOM give a false reading. To check
a reading, reverse the leads, and take a
second reading. lf the readings differ, the
component is affecting the measurement.
Jumper Wire
Use a jumper wire to bypass an open circuit.
A jumper wire is made up of an in-line f use
holder connected to a set of test leads. lt
should have a tive ampere fuse. Never
connect a jumper wire across a short circuit.
The direct battery short will blow the fuse.
Short Finder (Short Circuit Locater)
Shoft linders are available to locate shorts to
ground. The short finder creates a pulsing
magnetic field in the shorted circuit which you
can follow to the location of the short. lts use
is explained on page 15.
SHORT FINDER
To order any test equipment shown above,
contact your local tool supplier. For a list of
suppliers and tool numbers, refer to Acura
Required Special Tools and Equipment
Service Bulletin.
Troubleshooting Precautions
Before Troubleshooting
1. Check the main fuse and the fuse box.
2. Check the battery for damage. state of
charge, and clean and tight connections.
CAUTION:
. Do not quick-charge a battery unless
the battery ground cable has been
disconnected, or you will damage the
alternator diodes.
. Do not attempt to crank the engine with
the ground cable disconnected or you
will severely damage the wiring.
While You're Working
1. Make sure connectors are clean, and have
no loose terminals or receotacles.
2. Make sure multiple terminal connectors are
packed with dielectric (silicone) grease.
Part Number: 08798-9001 .
Pack with dielectric (silicone) grease
When connecting a connector, push it until it
clicks into olace.
Do not pull on the wires when
disconnecting a connector. Pull
only on the connector housings.
Most circuits include solid-state
devices. Test the voltages in these
circuits only with a 1o-megaohm or
higher impedance digital multimeter.
Never use a test light or analog meter
on circuits that contain solid-state
devices. Damage to the devices
may result.
