Power Relays
Relay Test
t{ormally-op€n Type:
1. Remove the power relay from its sockat.
2. Check continuity between relay terminals.
a There should be continuity between the A and C
terminals when power and ground ar€ connect-
ed to the B and D t€rminals
a There should be no continuitv wh€n power is dis-
connected.

Alternator Belt Inspection and Adjustment
Deflection Method:
Apply a force of 100 N (1o kgt, 22 lbJ) and measure the
deflection between the alternator and the crankshatt
pulley.
Detlsction:9-11 mm (0.35-O.43 inl
NOTE; On a brand-new belt {one that has be€n run
for less than five minutes), the deJlection should be
6-8 mm 1O.23-O.32 in) wh€n first measured. lf
the belt is worn or damaged, replace it.

lf adiustment is nocessarY:
1. Loosen the alternator adjusting nut and mounting
nur.
2. Move the alternator to obtain the proper belt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the deflection ot the belt.
NOTE: lt necessary, adiust the P/S pump belt (see
section 17) and A/C compressor belt lsee section
22t.

Boh Tsnsion Gaug6 Mothod:
Foltowing the gauge manuJacturer's instructions, attach
the belt tension gauge to the belt and measure the
tension.
Tension: 340-49O N (35-50 kgl, 77-110 lbfl
NOTE: On a brand-new belt (one that has been run
for less than tive minutes), tension should be
690-880 N (70-90 kgt, 154- 198 lbJ) when tirst
measured. lf the belt is worn or damaged, replace it.
lf adi$tmsnt is nscaasary:
1. Loosen the alternator adiusting nut and mounting
nut.
2. Move ths ahernator to obtain the proper bslt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the tension of the belt,
NOTE: lf necessary, adjust the P/S pump belt (see
section 17) and A/C compressor belt (see section
22t.
