Panel switch wiring

This circuit is also use operational amplifier IC LM324 to drive the VN64GA with the error signal and to control output voltage. This output voltage is pulsating DC , which is quite satisfactory for battery charging. This circuit also can be converted to the system regulated DC supply.
You do this by increased C2 and anoother electrolytic capacitor is added across the load. The respon time is very fast, determined by the op amp.

Schematic and troubleshooting below :

If the circuit not work , Perhaps the cause of :

• AC cable disconnected
• Transformer is damaged or leaking.
•  Broken or leaky diode.
• Installation of inverted foot elco.
• Instrallation of the components of the upside , particularly on the transistor , examine the placement of the feet emitter , collector and base.
• IC damaged.
• Soldering is less sticky.
• Line PCB damaged.

The following steps will be done to troubleshoot Vehicle wiring problems issues or circuit failures. Note that you just have to be compelled prepare some tools like jumper wire, voltmeter, ohmmeter and probing tools, before do some troubleshooting on your Vehicle wiring problems issues. Here are some steps you have to perform:

1. Verify problems issues
2. Verify any connected symptoms. try this by performing operational checks on parts that are in same circuit.
3. Analyze the symptoms. Use the wiring diagrams to see what the circuit is doing, where the problems issues possibly is happening and where the diagnosis can continue.
4. Isolate problems issues area
5. Repair problems issues
6. Verify correct operation.

* Jumper wire: check wire used to connect 2 points of a circuit. It may be used to bypass an open during a circuit.

* Voltmeter: this a voltage measurement tools. Note, connect the black result in known sensible ground and red result in the positive side of the circuit.

* Ohmmeter: this a circuit’s resistance measurement tools. Note that low or no resistance during a circuit means that sensible continuity.
