Can a bad voltage regulator be a good thing?
Can a bad voltage regulator be a good thing?
When your test shows a steady or intermittent high or low voltage output, the voltage regulator is possibly bad. Most voltage regulators fail by allowing a high voltage output, though. However, before going any further, check that all the connections to the alternator and battery are good and clean as described in the next section. 1.
Is there a way to bypass the voltage regulator?
There could be several ways to bypass the voltage regulator, depending on the charging system configuration for your particular vehicle model. If the rear of your alternator has a ‘test tab’, you need to short this tab to the alternator frame using a screwdriver while checking voltage output at the battery with the engine running.
What happens when the armature of a voltage regulator is broken?
When the armature is pulled down a set of contact points closes and the circuit is completed. When the magnetic field is broken (like when the generator slows down or stops) a spring pulls the armature up, breaking the contact points. An obvious failure mode is the contact points.
What should the voltage of a voltage regulator be?
Voltage Regulator Test Charging voltage can vary between 13.5 and 14.8 volts, depending on ambient temperature. In a nice, 70 F (21 C) day, you can expect a voltage regulator charging your car’s battery at about 14.2 volts. And the higher the temperature, the lower the charging voltage.
