Sierra 18-99532 DVA Adapter No Leads for Marine Ignition Testing

The Sierra 18-99532 DVA (Direct Voltage Adapter) is an essential diagnostic tool for testing marine ignition systems, stators, sensors, and charging systems. This adapter enables digital multimeters to accurately measure peak AC voltage on capacitor discharge (CD) ignition systems commonly found in outboard motors and marine engines.

How It Works:

DVA testing measures the absolute peak value of fluctuating AC voltage signals, which is critical for diagnosing marine ignition components. The adapter features a built-in bridge rectifier that converts AC voltage to DC, allowing your digital multimeter (set to DC voltage scale) to capture and display peak voltage readings. These peak readings are substantially higher than standard RMS AC values and are essential for accurate ignition system diagnosis.

Key Features:

• No built-in test leads - uses your existing multimeter leads for maximum versatility
• Compatible with digital multimeters when set to DC voltage scale
• Simplifies testing of electronic ignition systems, stators, sensors, and charging systems
• Prevents misdiagnosis of good ignition components as faulty
• Premium quality construction for long service life
• Meets or exceeds OEM specifications
• Backed by Sierra's limited lifetime warranty
