I Specialize in Electrical Diagnostics for Heavy Duty Equipment and I also provide on site Training

About Us

Why choose me?

I have over 21 years experience in Electrical Diagnostics and Driveability and I enjoy what I do.  Here is the catch though, my experience is solely on HD.  I am also a ASE Cerified Master Transit Bus Tech and a L2 Advanced level Specialist with numerous factory certifications.  I am also proficient in the use of a Oscilloscope with tons of experience using one.  So when you are ready to purchase a custom kit from Autonerdz I'm your man for custom training and great support not only from Autonerdz but me as well!

How We Help

I can come directly to your shop and Train your Techs from Beginning to Advanced Electrical, Scan Tool Use, Diagnostic Techniques, and also if you purchase a Custom Autonerdz Picoscope Kit from me I provide Training for the tool on site for a nominal fee or I can provide Training via screenshare on your laptop or desktop for free!  

Experience the Difference

I think you will enjoy working with me because I am a specialist in HD Diagnostics that emphasizes using and instructing the latest Diagnostic Techniques with known good examples of my work which include waveforms and scan data analysis.  My instruction is straight to the point, I'm going to show you real world techniques to help you fix vehicles right the first time and not guess.  Also coming soon I will be performing Mobile Diagnostics.  Stay tuned for details.  However if I'm at your shop while Training and you have a vehicle you need assistance on I would be more than happy to assist and turn the problem vehicle into a learning experience for your Technicians.
