What is the usual minimum cranking voltage specification?
The average cranking voltage was 11.28 volts, with the minimum at 11.16 volts. The maximum initial cranking amperage was 161.0 amperes with an average of 114 amperes during a 7-second extended cranking test.
How do you adjust a voltage regulator?
If the voltage, at which the reading becomes steady, occurs outside these limits, adjust the regulator by turning the adjusting screw 1/4 turn at a time clockwise to raise the voltage or counterclockwise to lower. The adjusting screw can be found on the back of the regulator facing the firewall.
How do you troubleshoot a regulator?
How to Troubleshoot an Auto Voltage Regulator
- Determine how to bypass the regulator on your alternator.
- Connect your voltmeter probes across the battery terminals to check the condition of the battery and record your base voltage reading.
- Turn off all electrical accessories and start the engine.
How do you test AVR?
You can do a simple test with the AVR still mounted on the AC generator. Wind the voltage trim pot up and down and see what happens to the AC generator output. You can also bench test any AVR with a variable output Autotransformer (variac) and some test load that represents the AC generator field resistance.
How do you test a 7812 voltage regulator?
Turn on the DC power supply and adjust the output voltage of about 8V or slightly larger. Or alternatively you can use a battery 9V-12V as voltage source. Look at the voltmeter panel when you set the voltage. Prepare a DC voltmeter readings on voltage range 50V to measure the output voltage of the IC 7805.
