When a wiring problem is suspected:
- Disconnect and clean the connector. Electronic connector cleaner can be used.
- Clean any corrosion from the connection with a soft bronze bristle brush (available at electronic supply stores).
- After cleaning the connection, coat the wire ends with dielectric compound if it was used previously.
Do not use color TV cleaner. It contains acids that will cause further corrosion of the connection.Do not use carburetor cleaner, brake cleaner, alcohol, or electromotive spray. The connector is held in plastic, which has a hydrocarbon base. A strong cleaner can ruin it.Do not touch the metal parts of the connector. Acid from your hands can begin the corrosion process.
