Who We Help: Singapore Cars Driving in Malaysia

MyMechanic provides cross-border roadside assistance for Singapore-registered vehicles throughout Malaysia—covering battery, alternator, fuse/relay, ignition, and power accessory failures, plus safe towing when needed. We focus on non-destructive checks first and aim to restore power on-site whenever possible.

Safety First: What To Do Immediately

• Pull over safely with hazards on; avoid blind corners or fast lanes; set reflective triangle where safe.
• If smoke or burning smell—cut ignition and step away.
• Avoid repeated cranking if lights dim heavily—can drain battery & strain starter/alternator.

Fast Checks That Often Solve the Problem

• Battery terminals: tighten loose clamps & clean corrosion.
• Fuses/relays: replace only with correct rating.
• Alternator symptoms: dim lights, battery lamp—stop and test.
• Key fob/immobilizer: try spare key or hold fob near start button.

Common Electrical Failures on the Road

• Dead/weak battery after short trips or leaving lights on.
• Failing alternator causing stalling or flat batteries.
• Moisture in switches/relays causing intermittent faults.
• Wiring or ground faults causing random warning lights.

What To Try—Step by Step (If Safe)

• Power cycle ignition to reset modules.
• Check fuse box for specific circuit; replace with same-amp fuse.
• Inspect battery for tight clean clamps.
• Jump-start using correct polarity; test alternator.

When to Call MyMechanic

• Repeated fuse blows, burning smell, or visible smoke.
• Crank/no-start with dim lights or clicking.
• Total loss of power while driving or charging light on.
• Windows/locks stuck in unsafe positions during rain/night.

Prevention Tips for Cross-Border Trips

• Test battery before travel; replace if borderline.
• Inspect & tighten terminals; carry terminal brush & jump cables.
• Watch for dim lights at idle or alternator warning lamps.
• Carry spare key fob battery and know manual override.
