No set thing.. Take it to a garage. The alternator may be faulty: only voltage of 13 or 13.5 (which is listed as acceptable but is not sufficient to start the battery as well as run headlights etc.), rather than 14 or greater (as is needed for this particular make and model). Another thing you should check is grounding. Be sure connections & ground straps are good. Be sure you have good battery cables & connections.
First start the car then pull off the positive on the battery if the car dies than you need a new alternator if the car keeps running u may need a new battery. A word of caution, testing an alternator that way can cause damage to the alternator. The alternator needs power to make power unlike the old generators from the past.
yes it will i have a optima battery in my 1995 marquis
Battery may have a dead cell and need replacing.
Alternator is not putting out a charge.
Then something is on pulling power from the battery. Check all lights and relays.
No, the battery for a 2005 Jeep Grand Cherokee is available from other sources. The price of the battery will vary depending on the quality of battery you purchase and the installation cost.
a timing chain has broken
Typically, a bad or "going bad" alternator.
Remove battery connections, then slacken the serpentine belt. Removal of alternator is simple and straightforward, 3 bolts, replace in reverse order.
If the battery is dead you will need a battery charger. If the battery is good and you have low amperage then you will need another alternator. Most parts stores will check it for you. If you are looking for MORE amperage then you would have to buy a larger amperage alternator.
Start engine and measure volts at battery, it should be at least 13
This usually means that you have a dead battery. Either from a bad battery, or a bad alternator.
