Smell for burnt parts, check fuse continuity. 📘 Step 2: Test Voltage Path Measure voltage at battery terminals (should be 27–28V DC when charging). If zero, proceed to relay or MOSFET section. 📘 Step 3: Replace Suspect Components 🔁 Relay: Commonly used is JQC-3FF or SRD-12VDC-SL-C ⚡ Charging MOSFET: Replace IRFZ44N / IRF3205 🧠 IC TL494 / LM324: Used for PWM and voltage control — replace if faulty. 📘 Step 4: Re-Solder & Clean Carbon/jumper the burnt track Use isopropyl alcohol to clean blackened areas 📘 Step 5: Test with New Battery Connect fully charged battery and test charging response. --- 📊 Basic Circuit Diagram (Relay Section): 📌 Important Notes: Always test with multimeter before replacing parts Use heat sink paste for MOSFET installation Never bypass relay permanently – it’s risky 🧰 Tools Required: Multimeter Soldering iron & flux Screwdriver Replacement components Agar chahen to main iska photo-based repair diagram bhi bana ke de sakta hoon. Batao – hand-drawn style ya digital schematic style chahiye?
