How to Troubleshoot

• Follow the soldering tutorial video or Assembly Instruction closely.
• Do NOT skip steps.
• Test the voltages as directed. If they are incorrect, stop and figure out the problem. Do not proceed until the voltages test okay.

If it's not working after assembly:

• Check all IC's to make sure 1) they are at the correct location; 2) they are in correct direction
• Check diodes to make sure their polarity is correct.

TP1 should be around 1.3V, and TP3 should be around 26V. If not, something is wrong with your power supply portion.
