X-TRACTOR ® 3A
CLEANING SOLENOID RESISTANCE TEST
PROCEDURE
1. Remove input power to the X-Tractor 3A.
2. Perform the Case Cover Removal Procedure.
3. Locate the cleaning solenoid. See Figure F.17.
4. Perform the Digital Solenoid Timer Removal Procedure.
5. Check the resistance of the cleaning solenoid coil. Normal coil
resistance is approximately 12.5 ohms. Also check the resistance
from one of the coil terminals to the ground terminal. It should be
very high. At least 500,000 ohms. See Figure F.18.
6. If the coil resistance is not correct or the coil is grounded, the
cleaning solenoid is faulty.
