3. h If required the available CCA Ah DIN amp JIS can easily be determined by multiplying the percent displayed times the battery s original rating For example a 600 CCA battery with 80 capacity available would have 480 CCA 80 x 600 available A 20Ah battery with 80 would have 16 Ah available Checking Charging System Alternator CHARGING SYSTEM TEST Note Prior to performing this test check the battery condition to make sure it is in good condition See In Vehicle Battery Test Instructions 1 Check first for a loose worn or broken alternator belt If okay proceed to 2 2 Connect the red clip to the positive battery terminal and the black clip to the negative terminal and start engine 3 With engine running and lights on the real time alternator Output voltage will be displayed The reading should display between 13 0 and 15 0 volts for 12V charging systems 4 Low charging voltage check belts for slippage Check connections from the alternator to the battery If no problems are found replace the alternator 5 High charging voltage Check for loose connections including the ground connection If OK replace the voltage regulator Newer alternators house the regulator inside In this case replacing the alternator is necessary STARTER TEST Note Check the battery condition to make sure it is in good condition before performing this test See In Vehicle Battery Test Instructions page 3 1 Con
4. nect the red clip to the positive battery terminal and the black clip to the negative terminal 2 Disengage the ignition Check manufacturer s instructions Read the voltage displayed while cranking the starter 3 Cranking Voltage is Normal For 12V systems the normal cranking voltage at the battery should be equal to or greater than 9 6 volts 4 Cranking voltage is Low If the cranking voltage is less than 9 6 volts starting system has a problem Check wires connections and starter Check manufacturer s specifications for 12V systems New Batteries Nearly all batteries will not reach full capacity until cycled 10 30 times A brand new battery will have a capacity of about 5 10 less than the rated capacity Inactivity can be extremely harmful to a battery New batteries that have been on the shelf for many months may show marginal or replace when tested depending on the storage conditions In that case always charge and retest the battery before replacing 9
