Not all scopes have the capability of AC input coupling, this makes it difficult to troubleshoot alternator ripple and other signals.
Not a problem with the AC Filter Test Lead. It does the job for you by filtering out the DC (steady) portion of the signal so you can concentrate on the AC (always changing) signal, making it easy work to diagnose alternator ripple.

You can also use the AES AC Filter Test Lead to perform a cranking compression test since it allows you to focus in on small fluctuations in battery voltage!
Includes datasheet with general setup instructions and two insulated alligator clips (red and black).
