Question: Why is my Hitachi EX200-5 failing to start even with a full battery?
Answer: Often, the culprit is a faulty start relay. If the 4251588 green relay has burnt internal contacts, it won't trigger the solenoid. Replacing the relay is the most cost-effective first step in troubleshooting.
Question: Can I use 4251588 interchangeably across different Hitachi models?
Answer: Yes, this specific part number is used in most EX-2, EX-3, and early ZX models. However, always verify the pin configuration before installation to protect your ECM.
