Chk-v9.04g Circuit Diagram !!better!! Access

The CHK-V9.04G circuit board is a common, standardized mainboard used in many budget-friendly induction cooktops (often referred to as "China-common" PCB designs). If you are looking at this diagram, you are likely either repairing a dead unit or trying to understand the power delivery of an induction heater.

• Always discharge the bulk capacitor (≥400V) using a 10kΩ 5W resistor before probing.
• Use an isolation transformer when scoping primary-side waveforms.
• Replace the main fuse only with the exact rating specified in the diagram.
• Do not operate the board without its heatsink; thermal runaway is rapid.
