Manufacturer

Sierra

<p>For nearly six decades, Sierra has established itself as one of the marine industry's most trusted names in aftermarket engine and drive parts. Founded as a specialized marine parts manufacturer, Sierra has grown into a comprehensive supplier of replacement components, instrumentation, and accessories for both recreational and commercial boating applications. Operating from their 300,000-square-foot distribution center in Litchfield, Illinois, Sierra serves boat owners and marine technicians worldwide with an extensive catalog of parts engineered specifically for the harsh saltwater environment.</p><h3>Marine Engine Excellence</h3><p>Sierra's reputation was built on delivering precision-engineered internal engine components and drive system parts that meet or exceed OEM specifications. Their <a href="/7570-sierra-engine-gasket-set-5404">engine gasket sets</a> provide critical sealing solutions for inboard and outboard motors, while their <a href="/7570-sierra-engine-complete-assembly-15341">engine complete assemblies</a> offer comprehensive replacement options for major overhauls. Each component undergoes rigorous testing to ensure reliability in demanding marine conditions, from corrosion resistance to temperature cycling performance.</p><h3>Instrumentation and Monitoring Systems</h3><p>Accurate instrumentation is essential for boat operators to monitor engine health and prevent costly breakdowns on the water. Sierra's comprehensive line of <a href="/7570-sierra-gauges-200483">gauges</a> includes everything from fuel pressure and temperature indicators to voltmeters and trim gauges, all designed with marine-grade materials that withstand vibration, moisture, and UV exposure. Their <a href="/7570-sierra-tachometer-gauge-1488">tachometer gauges</a> deliver precise RPM readings critical for optimizing engine performance and fuel efficiency. Supporting these instruments, Sierra's <a href="/7570-sierra-gauge-resistor-47908">gauge resistors</a> ensure proper signal conditioning and accurate readings across various sensor types and engine configurations.</p><h3>Expanded Product Portfolio</h3><p>In 2022, Sierra significantly broadened its scope beyond traditional marine engine parts to encompass a wider range of boating accessories and even outdoor power equipment components. This strategic expansion brought established marine brands like Shields and Moeller under the Sierra umbrella, creating a one-stop resource for marine maintenance and replacement parts. The company now offers fuel systems, electrical components, battery charging solutions, and NMEA electronics alongside their traditional engine parts lineup.</p><h3>Quality Backed by Industry-Leading Warranties</h3><p>What sets Sierra apart in the crowded aftermarket marine parts market is their commitment to standing behind every component they manufacture. Their warranty coverage extends beyond simple part replacement—it includes shop labor, haul-out fees, towing charges, and related incidental costs should a warrantied part fail. This comprehensive protection reflects the company's confidence in their manufacturing processes and quality control standards. For boat owners facing repairs far from shore or mechanics working on customer vessels, this peace of mind is invaluable. Whether you're maintaining an outboard motor, rebuilding an inboard engine, or upgrading your boat's instrumentation, Sierra's decades of marine industry experience and commitment to quality make them a reliable choice for keeping your vessel running at peak performance.</p>

Product Details

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

Replaces: CDI Electronics 511-9773NL

Application: Designed for use with shielded digital multimeters to diagnose marine engine ignition systems including outboards and stern drives. Essential for any marine technician or boat owner performing electrical troubleshooting.

Note: Test leads are not included with this adapter. Use your existing meter leads to connect to the adapter.
