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

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 terminals because of the remote sense feature. If you don’t, remove and reinstall an alternator in the proper sequence required, you risk damaging the internal resistor and a warranty denial. This video will help you understand the proper steps for installing the alternator equipped with remote sense without damaging it. We’Ll 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 alternators 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 the battery voltage to the remote sense terminal. This means that at any time, the battery cable is connected 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 hook 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 have rubbed 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, one remove all battery grounds, step two 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. Πρώτη, 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.
