(D) Use Of The Pickup During Wet Conditions
If the pickup becomes wet, it may operate intermittently or not at all. Although the pickup is water resistant, it is not waterproof. Water spray from rain or other sources may cause the pickup to stop producing an output signal. If this happens, the pickup should be removed from the engine and allowed to dry out thoroughly. If necessary, the pickup can be dried in an oven at approximately 50°C (122°F). After drying, the pickup should operate correctly. If it is not possible to keep the pickup dry, use the following procedure. If the pickup must be used during wet conditions, it may be possible to protect it from moisture by using a water displacing spray such as WD-40 (a trademark of the WD-40 Company). Remove the pickup from the engine. Thoroughly spray the pickup from all directions. Make sure the pickup is completely covered with the spray. Reinstall the pickup on the engine and check its operation. When water first contacts the pickup, the unit may stop working temporarily, but will start working again after the water has been displaced by the solution. If necessary, spray the solution on the pickup after installation on the injection line.(E) Permanent Installation On The Engine
If the pickup is to be permanently installed on the engine, install the pickup on the fuel injection line in the usual manner. Make sure the thumbscrew is hand tightened securely but not overtightened. Run the engine and check operation of the pickup. Make sure pickup and line are clean and dry. If the pickup is working correctly, use a can of spray paint to thoroughly paint the pickup from all directions. Several coats should be applied. Let the paint dry before operating the engine.Checking The Operation Of The Amplifier And Pickup
