## Overview

The Electronic Specialties 640 adapter upgrades your digital multimeter to accurately read peak voltages on CDI ignition coils, essential for precise diagnostics on outboard and small engines. Featuring a compact, half-size design with durable screw-on alligator clips, this professional-grade tool is OEM trusted and proudly made in the USA, meeting CE, RoHS, and UL certifications.

## Description

Dva adapter - for use with your digital Multimeter. This is the "original" direct voltage adapter supplied to several OEM's for reading peak voltages on CDI ignition systems. This is an essential tool for diagnosing ignition systems on outboard engines and other similar small engines. The adapter plugs into your Dmm and allows it to read peak voltages - without it, your Dmm can not detect the peak and the readings are random and unusable.

## Features

- Read Peak Volts on CD ignition coils with your existing digital multi-meter
- Adapts your digital multi-meter into a peak reading voltmeter
- High quality test leads with screw on/off alligator clips are incorporated into the adapter
- New, completely redesigned unit is half the size of the previous adapter
- Made in USA

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very nice
  

*by P***L on Reviewed in the United States on June 11, 2024*

This works great and did not break the bank.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great for diagnosing ignition dynamically
  

*by F***K on Reviewed in the United States on June 29, 2023*

This is a great tool.  Resistance measurements for stators and CDIs only tell part of the story.  Run the leads to the pickup and advance coils out of the stators during cranking and running to see if they're generating voltage.  If they are move it to the output of the CDI to coil.I'll never go back to relying on a bench test.  Great tool at a great price.  Wish I would've known about this tool sooner!

    The only tool to diagnose pulsing coil
  

*by B***N on Reviewed in the United States on January 4, 2024*

I am a motorcycle and ATV mechanic and I needed one of these to diagnose a stator in a Honda ATV.It worked perfectly, showed me that the sensor (Pulsing coil) was defective. I replaced it for 17.00 and got my quad running again !These used to be very expensive, but now, these are within my reach financially.
