Common Failures
Frequent issues include blinking indicators on power-up, units blowing fuses, no board lights, solid board lights, and corrosion. Common defective components causing these symptoms are electrolytic capacitors and TVS diodes. Some failures are attributed to battery overvoltage leading to blown diodes.

Preventative maintenance may include replacing electrolytic capacitors. Riveting and modifying terminal blocks, alongside the use of UV solder masks, may be part of the mechanical repair process.
