CHNT Starter Relay 3735910LD300 for JAC L22719 Trucks — a direct-fit DC12V relay with cross-reference JAC-L32044, 100% coil tested. The Starter Relay with OEM number 3735910LD300 is a verified direct-fit replacement for JAC L22719 and related light trucks. Manufactured by CHNT (正泰) and rated DC12V-1H, this relay is a critical electrical component in the engine starting circuit, responsible for switching the high-current starter solenoid circuit using a low-current ignition signal. It restores reliable engine cranking when the original relay fails due to contact wear or coil burnout.
- Real Shop Test Data: 100% coil resistance and contact continuity tested — coil resistance verified at [Insert value, e.g., 80–100 Ω] at 20°C, contact resistance ≤ [Insert value, e.g., 50 mΩ] [Report No. YM-RL-2025-XX].
- Proven Durability: Rated for [Insert cycles, e.g., 100,000+] switching cycles at rated load — verified by [Insert test method, e.g., electrical endurance bench test] [Report No. YM-RL-2025-XX]. CHNT brand quality with traceable batch codes (e.g., 20210405D).
- Installation Success Rate: [Insert %] direct plug-and-play fitment — confirmed across [Insert number] repair orders for JAC L22719.
- OEM Cross-Reference Verified: Replaces OEM 3735910LD300. Universal cross-reference: JAC-L32044. Do NOT confuse with 3735970LD300, which is a different CHNT relay variant (DC12V-1Z).
Replace your starter relay if you notice any of the following:
- Engine cranks slowly or not at all — single click or no sound from starter.
- Starter motor continues running after engine starts (relay stuck closed).
- Intermittent starting — works sometimes, fails other times.
- Audible clicking from the relay area but no starter engagement.
- Burn marks or melted plastic on the relay housing.
