Proper Replacement for Remote Sense Alternators | BorgWarner Delco Remy Genuine Products Tech Tip

In this Tech Tip video we explain the proper way to remove and replace alternators equipped with remote sense. Because of the remote sense feature, you risk damaging the internal resistor and a warranty denial if you don’t follow the exact removal and replacement sequence. To help avoid accidentally damaging the resistor, the steps explained in this video should be followed when removing an alternator with remote sense. --- http://delcoremy.com --- In this video we'll explain the proper way to remove and replace alternators equipped with remote sense. Before we get started, let's review what remote sense is and how it benefits the alternator. Remote sense is a feature on some Delco Remy alternators and utilizes a small sense wire that reads the actual battery voltage and signals the regulator to increase voltage output as needed, ensuring constant battery voltage. Non-remote sense-equipped alternators attempt to regulate off the battery connections on the alternator terminal. Because of the remote sense feature, if you don't remove and re-install an alternator in the proper sequence required, you risk damaging the internal resistor and warranty denial. This video will help you understand the proper steps for installing the alternator equipped with remote sense without damaging it. We will also explain why damage can occur when installations are not completed properly. Let’s get started. Here’s how it all works: The battery connects to the alternator’s large B+ terminal. Additionally, inside the alternator there is a wire connecting the B+ terminal to a resistor. This wire runs battery voltage through the resistor and, in turn, feeds battery voltage to the remote sense terminal. This means that any time the battery cable is hooked to the alternator, the remote sense terminal also has battery voltage present—even if the remote sense terminal is not being used. When there is a wire hooked to the remote sense terminal, the wire will also be fused and terminated to battery positive voltage as well. The fuse protects the circuit should a rub through to ground occur. Since the internal circuit bleeds back battery current, simply removing the fuse does not terminate battery voltage at the remote sense terminal. It is still hot. And if the remote sense terminal or wire touches any grounded metal during removal and replacement process, the resistor will be immediately damaged. To help avoid accidentally damaging the resistor, follow this sequence when removing and replacing alternators with remote sense. To remove the alternator, follow these six steps in order: Step 1: Remove all battery grounds. Step 2: Remove the alternator ground. Next, locate and remove the remote sense fuse. Step 4: Remove the B+ cable from the alternator positive post. Then, remove the remote sense terminal wire. And finally, remove the alternator itself. Now, let's go over the proper sequence for installing the alternator with remote sense. First, mount the alternator. Step 2: Install the remote sense wire. Now, install the remote sense fuse. Step 4: Install the alternator positive cable. Step 5: Install the alternator ground cable. And, last, install all battery grounds.
