The new Delphi ASVR voltage regulator replaces the older version manufactured by Delco Electronics. In some instances, the new number replaces more than one previous application, as shown in the table below.
A great deal of engineering was needed to make these regulators replace multiple earlier regulators. These regulators have been tested in various applications to ensure their compatibility.
A few cautions must be observed when testing these regulators, mainly when not actually installed in the vehicle. Remember, these regulators were made to work on vehicles, but they may not function quite the same on a regulator tester or alternator tester that does not fully simulate true vehicle conditions.
These regulators may not test correctly on all voltage regulator testers. They will test correctly on voltage regulator testers that simulate actual vehicle conditions. Check for compatibility with your voltage regulator tester manufacturer. You may need to upgrade your voltage regulator tester.
When testing on an alternator test stand, the B+ wire must be attached first to the alternator, before the regulator wire is connected. If your alternator tester disconnects the battery terminal from the B+ supply when the motor is off, you will need to reconnect the lead to accurately simulate the alternator in the vehicle and avoid damaging the regulator. Next, install the regulator connector. After testing, the procedure is reversed. Always remove the regulator connector before disconnecting the B+ wire. The rotor should cease spinning before the B+ wire is disconnected. This will ensure that the voltage regulator is biased correctly and will prevent voltage spikes from damaging the regulator. Failure to follow this procedure can result in damage to the voltage regulator by “false biasing” it.

The regulator is turned on by the PCM in most late model applications. If a fault code was set when the original alternator failed, then the error codes must be reset for proper operation. If the fault codes are not cleared, the charge light may stay lit.
