Trusted AVR (Amperage, Voltage and Resistance) Test In Hamilton, ON

AVR testing is a precise electrical diagnostic service that measures amperage, voltage, and resistance to identify hidden faults in a vehicle’s starting, charging, and related electrical circuits. It matters because weak connections, failing components, and excessive resistance can cause hard starts, charging problems, dim lighting, and intermittent electrical failures long before a part completely quits.


SIGNS YOU NEED AVR TESTING

- Slow cranking or a no-start condition
- Dim headlights, interior lights, or flickering electrical accessories
- Battery warning lights, repeated dead batteries, or charging system concerns


OUR AVR TESTING PROCESS

Our technicians use specialized test equipment to measure how your vehicle’s electrical system is performing under load, checking voltage output, current flow, and circuit resistance at the battery, alternator, starter, cables, and key connections. This diagnosis helps pinpoint whether the problem is a weak component, a poor connection, or excess resistance so the right repair can be made without guesswork.
