Component Testing

CAUTION:

Refer to Test Probe Caution

NOTE:
  • Before testing the coax cable, check the cable exterior for being pinched, cut, damaged, or having loose connections at the components, which can cause reception issues.
  • To prevent false readings when testing the center coax terminals, use care not to ground the test probe on the outer housing/shield.

Coax Cable Test

  1. Ignition OFF, disconnect the coax cable at both components.
  2. Test for less than 5 Ω between the coax cable center terminal end to end.
    • If 5 Ω or greater 

      Replace the coax cable.

    • If less than 5 Ω 
  3. Test for greater than 5 Ω between the coax cable outer shield end to end.
    • If 5 Ω or greater 

      Replace the coax cable.

    • If less than 5 Ω 
  4. Test for infinite resistance between the coax cable center terminal and the coax cable outer shield.
    • If less than infinite resistance 

      Replace the coax cable.

    • If infinite resistance 
  5. All OK.
