� BCT-460NAV Operator's Manual Hand Held-Accuracy with a Pulsed 120 Amp Load Heavy Duty The BCT-460NAV is the ultimate hand-held tester. It is the industry's answer to portability in a professionally accurate load tester and system analyzer.
Digital Pulse Load. The BCT-460NAV is user friendly. It guides you through the test and tells you what to do next. Caution: The BCT-460NAV grill may get hot after repeated use. Be sure to hold the unit from the side grips only. Keep hands away from the grill. Keep oil and liquids away from the grill and load coils.
Using the Optional Current Probe ............42 Trouble Shooting ................. 43-44 Warranty ....................45 Contact Information ................46 Note: The BCT-460NAV performs a complete electrical system test that checks the battery pack, starter cable voltage drop, starter test, alternator cable voltage drop, and alternator test.
Do not attempt to Load Test or charge a battery under 20 degrees. Allow the battery to warm to room temperature before testing or charging. Warning! Never attach the BCT-460NAV to a battery that is connected to any other tester or charging unit. Damage may result. WARNING! This device is only to be used on 12V and 24V electrical systems.
INSPECTION Valid heavy duty electrical system testing depends on all the components being in good operating condition. In addition, the battery MUST have sufficient charge for testing. Carefully perform the following steps before attempting any electrical diagnosis. VISUAL CHECK Inspect Belts for cracks, glazed surface and fraying. Tighten loose belts. Inspect Battery for terminal corrosion, loose or broken posts, cracks in the case, loose hold-downs, low electrolyte level,...
WIRELESS COMMUNICATION BLUETOOTH The BCT-460NAV uses Bluetooth to communicate between the control module and load module. This allows you to make the connections, remove the control module and the run the tests from inside the vehicle. The BCT-460NAV control module and load module come paired from the factory.

If the alternator fails due to high voltage regulation and it has remote sense the BCT- 460NAV will instruct the user to disconnect the remote sense wire and repeat the governor speed test.
VOLTAGE DROP TEST (Starter Cable Test) The voltage drop test allows you to measure the voltage drop across both the positive and negative cables running from the battery to the starter and alternator or any other device within your vehicle. This test can be used to deter- mine if the cables or connections are the cause of any problems.
VOLTAGE DROP TEST (Charging Cable Test) Select individual tests, then To set the test select the V DROP Test from current, press the Test current box the main menu. and a numeric keypad will appear. Enter in the alternator output for the vehicle you are testing.
VOLTAGE DROP TEST (Generic Cable Test) Select individual tests, then To set the test current, select the V DROP Test press the Test current box from the main menu. and a numeric keypad will appear. Enter in the test current for the circuit you are testing.
NOTE: If a total system voltage drop greater than 500mV is measured, the BCT-460NAV will show a failed voltage drop test. MAGNETIC CIRCUIT TEST The Magnetic switch circuit supplies a path for current to the coils of the starter solenoid with minimum voltage drop.
USING THE OPTIONAL CURRENT PROBE The Current Probe is optional. This section explains the proper use of the Current Probe, but is not required to run any of the tests. It only provides assured accuracy for those wanting these results. When the probes is not clamped around a cable push and turn to Zero the current probe.
TROUBLESHOOTING PROBLEM SOLUTION BCT-460NAV Does Not Read This is most commonly due to the LM (load module) not powered on, or a loss of BlueTooth Battery Temperature connection between the CM (control module/Tablet) and LM. 1) Make sure the LM is powered on & charged. Observe the LED indicator. If the indicator is not lit, push and release the LM button to “wake up”...
