Appendix B
Additional Troubleshooting Information
The troubleshooting procedure presented on the following pages has been excerpted from a laminated card entitled: Troubleshooting Charging and Air Supply Systems (BW1779). The complete card can be ordered from the Bendix Marketing Center at www.bendix.com. It is presented here because of the air dryers connection to the supply air system and for convenience. The procedure is not all inclusive but rather represents the most commonly encountered complaints.
