Component Testing

Relay Test 

1. Ignition OFF, disconnect the RAP relay.
2. Test for 70-110 ohms between terminals 85 and 86.
   • If the resistance is not within the specified range, replace the relay.
3. Test for infinite resistance between the following terminals:
   • 30 and 86
   • 30 and 87
   • 30 and 85
   • 85 and 87
   • If not the specified value, replace the relay.
4. Install a 20 amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Test for less than 5.0 ohms between terminals 30 and 87.
   • If greater than specified, replace the relay.
