Inspection

Power Relay Inspection (Type A)Check the circuit between the terminals for continuity.

A. Front Defogger Relay B. IGN2 Relay C. Fan Relay D. Alarm Horn Relay E. IGN1 Relay F. Cooling Fan Relay No. 1

G. Cooling Fan Relay No. 2 H. Starter Relay I. Rear Window Defogger J. Horn Relay K. ACC Relay L. Fuel Pump Relay

1. 1
   There should be continuity between terminals No. 30 and No. 87 when battery voltage and ground are applied to terminals No. 85 and No. 86.
2. 2
   There should be no continuity between terminals No. 30 and No. 87 when battery voltage is disconnected.

   

   

3. 3
   There should be continuity between terminals No. 30 and No. 87 when battery voltage and ground are applied to terminals No. 85 and No. 86.
4. 4
   There should be continuity between terminals No. 30 and No. 87 when the power is off.

   

   

5. 5
   There should be continuity between terminals No. 30, 87A and No. 87 when battery voltage and ground are applied to terminals No. 85 and No. 86.
6. 6
   There should be no continuity between terminals No. 30, 87A and No. 87 when battery voltage is removed.

   

   

   

7. 7
   Make sure that there is no play in the fuse holders and that the fuses are securely installed.
8. 8
   Is the rating of the fuse specified correctly for each circuit?
9. 9
   Is there a blown fuse? If a fuse must be replaced, be sure to use a new fuse of the same capacity. Always determine why the fuse blew first and fully correct the problem before installing a new fuse.
