U may deal a low battery condition,as the jump worked on ur starter. Ceck recharge alternator rate (alternator condition belt,plugs,ussualy gets a red worning on dash low charge rate) .Ceck battery level(if apply)/clean connectors.Replace battery if ended. Ceck for over draining condition (shortcircuit,lights/radio left on) cheers,let us know if figured out.
ARE YOU HAVING PROBLEMS STARTING? WHAT IS YOUR CONCERN? 13.8 VOLTS IS PRETTY GOOD FOR DIESEL ALTERNATORS I'VE SEEN IN MY EXPERIENCE WITH THE DODGE DIESELS
The battery on a Dodge Caravan is subject to the same drainage issues every conventional automobile battery has. If the alternator does not produce enough current to recharge the battery, it will lose its charge over time. If the voltage regulator is not functioning properly it can impair the ability of the battery to stay charged. If the operator leaves the headlights on, or the door open or any number of other accessories that draw electricity from the battery while the engine is not running, the battery will eventually die. Loose battery cables can also keep the alternator from supplying current back to the battery the votage regalator usally is first to go out. thanks
Well in order to check the alternator you must have a fully charged battery. I would try to charge battery and see if it will take a charge. If not, replace it then test the alternator.
Wire the "#1" terminal to the ignition wire from the key switch. This connection is responsible for making sure the alternator only engages when the car is powered on.
Wire the "#2" terminal to the positive battery line. This connection will insure the alternator only engages when the proper battery voltage is reached.
Check your battery and check the ground wire from battery. Make sure all your wires are clean and good connections. A bad battery will not charge and a dead battery will not charge a alternator maintains a battery not charge a battery, so charge your battery completely before checking that the alternator is working. Check all the wires going to the starter for good tight and clean connections . Hope this helps...
