⚡ Hybrid High‑Voltage Isolation Testing Manchester
Identify Dangerous HV Leaks & Electrical Faults Across Greater Manchester
High‑Voltage Isolation Faults Are One of the Most Serious Hybrid Issues
Your hybrid’s high‑voltage system must remain perfectly insulated from the chassis. If insulation breaks down anywhere in the HV system, the vehicle may:
- Trigger “Check Hybrid System”
- Enter limp mode
- Shut down completely
- Fail to start
- Overheat
- Blow HV fuses
- Become unsafe to drive
Our hybrid high‑voltage isolation testing service in Manchester detects insulation breakdown in the battery, inverter, MG1/MG2 motors and HV cabling.
This is a critical safety test for any hybrid showing electrical instability.
🔋 What High‑Voltage Isolation Testing Includes
- Full HV insulation resistance test — detect leaks to chassis ground
- Inverter isolation check — identify internal inverter faults
- MG1/MG2 motor isolation test — detect winding breakdown
- HV cable inspection — check for damage, corrosion or moisture
- DC‑DC converter isolation test — confirm safe 12V conversion
- Battery module isolation analysis — detect internal leakage
- Cooling system moisture check — ensure no coolant contamination
- Hybrid ECU scan — read isolation‑related fault codes
Isolation faults can cause sudden hybrid shutdown — early detection is essential.
