12 ALTERNATOR Insta-CheckTM Predictive Diagnostic Module No charge Partial Charge Over Charge voltage falls below 12.5 and > 600 RPM voltage over 12.5 and > 600 RPM Qualcomm Keyboard Display Qualcomm Keyboard Display Qualcomm Keyboard Display Qualcomm Keyboard Display Defective Alternator, critical, turn off all unnecessary loads and immediately get to a repair facility. Defective Alternator, critical, turn off all unnecessary loads and immediately get to a repair facility. Defective Alternator, not critical, report to operations. Turn on electrical loads. Lights, blower motors,etc. Report to operations.

13 Low Voltage Disconnect Functions Battery voltage drops to 12.3 volts, the LVD activates. Qualcomm Keyboard Display Starts Clock at 12.3 volts Checks Voltage Every 60 Seconds If Voltage Falls to to 30 Minutes to 12.1 v Critical, either high loads staying on or marginal batteries. Must be restarted A.S.A.P. 31 to 90 Minutes to 12.1 v Small load remaining on. Need to restart within one hour. 91 to 180 Minutes to 12.1 v Very small load remaining on. Need to restart in near future volts in less than 60 minutes from original 12.3 volts activation 11.5 volts in more than 60 minutes from original 12.3 volts activation Qualcomm Keyboard Display Qualcomm Keyboard Display If loads are turned off, wait 5 min. before starting. Truck will not likely start. Considerable time to recharge will be required before starting.

15 Where is the Practical Limit? Approaches Reactive Periodic Inspection Predictive Tool Kits EDI SAIM InfoLink TM System Statistics Based Maintenance

16 Optimum Schedule for Preventive Maintenance

17 Information Trumps Iron, Again Clean, understandable, significant data is the first critical step. Information has time & place utility. Data Information Knowledge Wisdom

18 Key Fleet PPM Technologies: On-Vehicle Communication Multiplex Supply Hose (not chain) Diagnostic Force Multipliers CU / Cme Mobile Video Expert (decision tree) Systems PC and PDA Based Software to analyze J1939 data Functional Consumer Conditioning (process) R & R Training
