- Check input voltage, whether working or not.
- Check the installation of the pins of components.
- Chek transistor , at input voltage , base , and output voltage.
- Check IC input voltage and output voltage , there or not.

This is very simple charger 9V - 30V battery charger with main operation by IC LM317L and 2N222 transistor. Direct input DC voltage , the recomended capacitor is 1000uf. It can be filtering Output voltage and make long-lasting battery. And easy to make this circuit , without using the PCB would be able to.See the Charger Schematic and troubleshooting below :
