390PT Battery Analyzer Starting/Charging System Tester For testing 6- and 12-volt batteries and 12- and 24-volt charging systems
Test Procedures / Operating Instructions IMPORTANT: 1. For testing 6 and 12 volt batteries, and for testing 12 and 24 volt charging systems. 2. Suggested range of operation 32ºF (0ºC) to 122ºF (50ºC) in ambient temperature. 1 LEGEND 4 5 1. LCD Display 2. UP/DOWN Button 2 3 3. ENTER: function selection/ confirm choice 4. Positive Clamp (RED, +) 5. Negative Clamp (BLACK, -) WARNING: 1. Working in the vicinity of a lead acid battery is dangerous.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water for at least ten minutes and get medical attention immediately. 5. NEVER smoke or allow a spark or flame in vicinity of battery or engine. 6. Be extra cautious to reduce risk of dropping a metal tool onto the battery. It could spark or short-circuit the battery or other electrical parts and could cause an explosion. 7.

One of six results will be displayed: GOOD & PASS : The battery is good & capable of holding a charge. GOOD & RECHARGE : The battery is good but needs to be recharged. RECHARGE & RETEST : Battery is discharged, the battery condition cannot be determined until it is fully charged. Recharge & retest the battery. GOOD & PASS xx.
SYSTEM TEST 1. Press «ENTER» button, you will view the following screen: 2. Turn off all vehicle accessory loads such as lights, air conditioning, radio, etc. Before starting the engine. SYSTEM TEST xx.xxV TURN OFF LOADS START ENGINE 3. When the engine is started, one of the three results will be displayed along with the actual reading measured. CRANKING VOLTS NORMAL The system is showing normal draw. Press «ENTER» to perform the charging system test.
HIGH CHARGING VOLTS WHEN TEST AT IDLE ALT. IDLE VOLTS xx.xxV HIGH The voltage output from the alternator to the battery exceeds the normal limits of a functioning regulator. Check to ensure there is no loose connection and the ground connection is normal. If there is no connection issue, replace the regulator. Since most alternators have the regulator built-in, this may require that you replace the alternator. The normal high limit of a typical automotive regulator is 14.7 volts +/- 0.05.
CHARGING SYSTEM VOLTAGE LOW WHEN TESTING WITH ACCESSORY LOADS The alternator is not providing sufficient current for the ALT. LOAD VOLTS system’s electrical loads and the charging current for the xx.xxV LOW battery. Check the belts to ensure the alternator is rotating with the engine running. If the belts are slipping or broken, replace the belts and retest. Check the connections from the alternator to the battery. If the connection is loose or heavily corroded, clean or replace the cable and retest.
What is a VRLA battery? Valve Regulated Lead Acid Battery – This type of battery is sealed and Maintenance Free. It uses special pressure valves and should never be opened. The valve(s) open when a preset pressure is realized inside the battery and lets the excess gas pressure out; the valve then resets itself. Gel and AGM Batteries are VRLA battery types.
