Cadillac Alternator Problems

An alternator is an electromechanical device that is designed to turn mechanical energy into electrical energy in the form of alternating current. In a Cadillac, an alternator is used to charge the battery and to supply power to the electrical system in the car when its engine is on. With a well performing alternator, the battery gets charged continuously so there is no need to worry about a lack of energy. However, when the alternator becomes defective, one is sure to encounter problems.

Read on to find out how a few commonly asked questions on Cadillac alternators have been answered by the Experts.

How much would it cost to replace a Cadillac alternator on the Cadillac Escalade?

The cost of the alternator is around $312, and the labor time guide calls for just under an hour to complete the job, but one could expect to pay for a full hour as most shops round up to the nearest hour). The labor rates vary from shop to shop, but for a job of this type, a "fair" labor rate can by anywhere from $85-$125 per hour. It will probably be a good idea to shop around and find a reputable shop that has a warranty on their parts.

In a Cadillac CTS, does the error message ‘check charging system’ suggest a defective Cadillac alternator?

It is possible that the alternator is defective. The first thing to do is to check for power at the battery cable hookup on the back of the alternator. If there is power, replacing the alternator should solve the problem.

What is the correct way to install a Cadillac alternator on an 1984 Cadillac Eldorado?

The positive battery cable should be connected to the alternator output stud (nut). The orange wire which originates from the +battery cable goes to the terminal ‘A’ of the ‘two wire’ connector. The brown wire which originates from the cluster ‘no charge’ indicator goes to the terminal ‘B’ of the ‘two wire’ connector.

Where do the wires from the engine harness connect to on the Cadillac alternator?

Case details: Replaced harness because the old one snapped.

Typically, there is only one small red wire that comes from the engine harness and connects to the L terminal of the Cadillac alternator. Once the old connector and harness are cut out, the red wire can be seen coming out of the engine harness.

When a Cadillac Catera has trouble starting, is it an indication of a faulty Cadillac alternator?

Case details: Need to jumpstart frequently, wires that connect to the battery get hot, stereo turns off while driving.

There could be four possible issues. It could be a bad battery, a faulty alternator, a bad battery and a faulty alternator, or a drain that is pulling the battery down. The first step could be to have the battery tested. Modern testers can tell the difference between a bad battery and one that is simply low on charge. If the battery tests badly, a new battery could be purchased. The alternator could be tested to make sure it is charging above 14 volts at idle. One needs to make sure it pulls the maximum amount of amperage that is specified. If it charges properly, the battery alone is the issue. If it doesn’t charge, the alternator could have been damaged by the bad battery. If both items test well, a drain is present and needs to be isolated.

The Cadillac alternator being an extremely important part in a vehicle, if defective, problems could be encountered. When problems arise, being unaware of how to handle them, could lead to questions. When questions arise, turning to an Expert would be best.
