The MDX-670P Analyzer
WARNING: This page is about a different variant/trim than selected.
The MDX-670P battery conductance and electrical system analyzer tests batteries as well as starting and charging systems for vehicle.
It displays the test results in seconds and features a built-in printer to provide a copy of the results.
CAUTION:
- Because of the possibility of personal injury, always use extreme caution and appropriate eye protection when working with batteries.
- When charging battery by test result, Battery must be fully charged. To get accurate test result, battery surface voltage must have subsided ahead before test when you test battery after charged. (See following Battery Test Results)
NOTE:
- When testing the vehicle with old diesel engines, the test result will not be favorable if the glow plug is not heated. Conduct the test after warming up the engine for 5 minutes.
- Connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal.NOTE:
- For a proper connection, rock the clamps back and forth. The tester requires that both sides of each clamp be firmly connected before testing. A poor connection will produce a CHECK CONNECTION or WIGGLE CLAMPS message. If the message appears, clean the terminals and reconnect the clamps.
- Scroll to and select IN VEHICLE or OUT OF VEHICLE for a battery not connected to a vehicle.NOTE:
- Following an IN VEHICLE test you will be prompted to test the starting and charging systems.
- Scroll to and select REGULAR FLOODED, AGM FLAT PLATE, or AGM SPIRAL where applicable.NOTE:
- If the vehicle equipped with ISG function, select the AGM FLAT PLATE.
- Scroll to and select the battery's rating system.NOTE:
- Mostly, the CCA value is marked on the battery label, but sometimes marked EN or SEA value. Select one of them.
- CCA: Cold Cranking Amps, as specified by SAE. The most common rating for cranking batteries at 0°F (-17.8°C).
- EN: Europe-Norm
- SAE: Society of Automotive Engineers, the European labeling of CCA
- Set the selected rating value displayed on the screen to the value marked on the battery label by pressing up and down arrow buttons.
- Press ENTER to start test.
- After several seconds the tester displays the decision on the battery's condition and the measured voltage. The tester also displays your selected battery rating and the rating units.
Battery Test Results
Result On Printer Remedy GOOD BATTERY No action is required. GOOD RECHARGE Battery is in a good state. Recharge the battery and use.
You have to follow instruction below when you charge battery and retest, otherwise test result can be inaccurate. (See 'Charge and Retest method after battery charge' below.)CHARGE & RETEST Battery is not charged properly. - Charge and test the battery again.
You have to follow instruction below when you charge battery and retest, otherwise test result can be inaccurate. (See 'Charge and retest method after battery charge' below.)REPLACE BATTERY Replace battery and recheck the charging system. - Improper connection between battery and vehicle cables may cause "REPLACE BATTERY", retest the battery after removing cables and connecting the tester to the battery terminal directly prior to replacing the battery.
BAD CELL REPLACE Charge and retest the battery. - If recommends "REPLACE BATTERY", replace the battery and recheck the charging system.
[Charge and Retest method after battery charge]
Battery charge
Set battery charger to 'Auto Mode' (The Mode that charging current drops as the battery charges.) and charge battery until charging current down close to zero or the charger alerts you with an alarm when charge is complete. (Minimum charging time recommended: More than 3 hours with Auto Mode that explained above)
- If battery is not fully charged, battery surface voltage will be high while the amount of current charged (CCA) in battery is low. If you measure the battery under this condition, tester may misjudge that battery sulfation occurred because the amount of current in battery is too low in comparison with battery voltage.
* Surface voltage: When battery is charged electrolyte temperature increases and chemical reaction become active resulting in an excessive increase of battery voltage.
It is known that it takes approximate one day to subside this increased surface voltage completely.
Battery Test after charge
Do not test battery right after the charge. Test battery after battery surface voltage has subsided as instructed in the following procedure.
- When battery charge is complete, install the battery in the vehicle.
- Put IG key to ON position and turn on head lamp with low beam, and wait 5 minutes. (Discharge for 5 minutes)
- Turn off the head lamp and IG key, and wait 5 minutes. (Waiting for 5 minutes)
- Remove +, - cable from the battery and test battery.
NOTE:- For an in-vehicle test, the display alternates between the test results and the message "PRESS FOR STARTER TEST".
NOTE:- Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the proper tension, will prevent the engine from achieving the RPM levels needed for the test.
- Press the ENTER button to proceed with the starter test.
- Start the engine when prompted.
- The tester displays the decision on the starter system, cranking voltage, and cranking time in milliseconds.
Starter Test Results
Result On Printer Remedy CRANKING VOLTAGE NORMAL System shows a normal starter draw. CRANKING VOLTAGE LOW Cranking voltage is lower than normal level. - Check starter.
CHARGE BATTERY The state of battery charge is too low to test. - Charge the battery and retest.
REPLACE BATTERY Replace battery. - If the vehicle is not started though the battery condition of "GOOD BATTERY" is displayed, check wiring for open circuit, battery cable connection, starter and repair or replace as necessary.
- If the engine does crank, check fuel system.
NOTE:- For an in-vehicle test, the display alternates between the test results and the message "PRESS FOR CHARGING TEST".
Step 3: Charging System Test
- Press the ENTER button to proceed with the charging test.
- Rev the engine with loads off. (Following the on-screen prompts)
- The message that engine RPM is detected will be displayed on the screen, idle the engine.
- Turn on electrical loads (air conditioner, lamps, audio and etc). Press ENTER to continue.
- Turn on electrical loads (air conditioner, lamps, audio and etc). Press ENTER to continue.
- The message that engine RPM is detected will be displayed on the screen, idle the engine.
- Turn off loads and engine.
- The Charging System decision is displayed at the end of the procedure.
Result On Printer Remedy NO PROBLEMS System is showing normal output from the alternator. NO OUTPUT No alternator output detected. - Check all connections to and from the alternator, especially the connection to the battery. If the connection is loose or heavily corroded, clean or replace the cable and retest.
- If the belts and connections are in good working condition, replace the alternator. (Older vehicles use external voltage regulators, which may require only replacement of the voltage regulator.)
LOW OUTPUT Alternator does not supply charging current to battery and electrical load to system fully. - Check belts and alternator and replace as necessary.
HIGH OUTPUT The voltage from alternator to battery is higher than normal limit during voltage regulating. - Check connection and ground and replace regulator as necessary.
- Check electrolyte level in the battery.
EXCESSIVE RIPPLE The voltage from alternator to battery is higher than normal limit during voltage regulating. - Check alternator mounting and belts and replace as necessary.
CHARGE BATTERY The starter voltage is low and the battery is discharged. Fully charge the battery and repeat the starter system test. REPLACE BATTERY Battery must be replaced before the starting system can be tested. - Press the BACK/PRINT button to print the test results or MENU to return to the Options Menu.
