Tech Tip Short: Why Voltage Stability Matters

In this Motor Age Tech Tip, Rick Urso demonstrates the importance of voltage stability during module programming and ADAS calibration. He compares a clean power supply for diagnostics — the ESS6100 smart charger from Associated Equipment — with a traditional battery charger, highlighting how unstable voltage can damage modules or corrupt programming. Maintaining proper vehicle voltage stability during programming is critical, as even minor spikes or dips can pose serious risks. Urso explains why module programming voltage requirements matter and shows real-time scope readings to prove it. Watch the full video to see why clean power matters and avoid traditional battery charger risks.
