3. Remove the component barrier. (See Remove the component barrier on page 90.)
4. Detach the front panel. (See Detach the front panel on page 92.)

6. Measure the resistance from the orange wire to the blue wire. It should measure less than 10 Ω. If it measures high
resistance, the cap-sensor switch circuit is open.
7. Make sure the torch plunger moves smoothly. If it does not, replace the torch body. (See Replacing the torch body on
page 178.)
8. Make sure the consumables are correctly installed. Adjust the consumables if necessary.
9. If the torch parts mentioned in step 7 and step 8 are working properly, the cap-sensor switch is faulty or the torch
lead has a broken wire. Replace the faulty part. (See Replacing the cap-sensor switch on page 181 or Replacing the
torch lead on page 182.)
Push tab toward connector.
