22.8 Troubleshooting power supplies

Power supply systems may include batteries, charging regulators, and a primary power source
such as solar panels or ac/ac or ac/dc transformers attached to mains power. All components
may need to be checked if the power supply is not functioning properly. Check connections and
check polarity of connections.
Base diagnostic: connect the data logger to a new 12 V battery. (A small 12 V battery carrying a
