Dodge Repair Questions? Ask a Mechanic for Answers ASAP
hello . I can assist you with this . The alternator charge lead goes from the alternator to the right side battery . The right side Positive battery cable runs from the positive molded battery terminal accross the radiator support to a " lug " terminal at the left side positive molded battery terminal " bolt/stud " . I have encountered the problem that you are describing . The usual cause of what you experienced is usually caused by a dirty/corroded/loose connection at the left side positive battery terminal where the right side cable connects to the " bolt/stud " . the loose/dirty/corroded connection at that point creates high resistance not allowing the alternator to supply sufficient " Amperage " to maintain the battery charge . Additionally the sensing circuit for the alternater sees a low voltage situation and commands the alternator to charge more resulting in the indicated high voltage in your instrument cluster . My recomendation is to remove ALL the battery terminals , cables and clean everything extremely well with a wire brush and then reconnect everything . That is a very common problem with these Dodge Trucks .
hi . I am sorry . I miss read the voltmeter part . If the volt meter was reading low , I still suspect the same issue with your vehicle . What condition do the connections appear to be in ? is there visible corrosion on the battery terminals ( " Fur " ) ? I still think you will find an issue at the cross over cable from the passenger side battery at the driver side positive . Check the connections , clean them as I have suggested .
no , There is no breaker or " protection " On that part of the electrical/charging system . if you have a voltmeter check your voltage readings with the engine rinning and some loads on ( headlights , heater , etc ) Check the voltage at the alternator output stud , using the alternator case for your ground reading , then measure the voltage at the right side battery positive and negative and next the left side battery positive and negative , recheck again after it has been running like that for about 15 minutes also watch your voltmeter in the dash for any change .
