Rosedale Tech alumni and internationally recognized YouTube sensation, Paul “ScannerDanner” is excited to lead technicians through this one-day diagnostics seminar.  The seminar will cover:

Input Circuits

  • How to avoid time wasting, manufacturer flow charts
  • Operation of the 5v reference circuit
  • Warnings on shorting a 5v reference circuit
  • How much stress does a test light put on a 5v regulator
  • Using the 5v bias on input circuits
  • Injecting voltage into sensor circuits
  • Can a signal circuit be damaged by higher than normal voltage
  • Internal bleed resistor function
  • Resistance testing vs voltage drop testing
  • Voltage divider circuits
  • Scan data substituted values and data PID updates
  • Voltmeter impedance and its effects on low voltage circuits
  • Diode meter vs ohmmeter for integrity testing
  • Using your body as a variable resistor
  • Wiring identification without a wiring diagram
  • Using the voltage drop caused by a voltmeter for identification
  • How much current can a sensor ground circuit handle
  • Using a test light for integrity testing
  • Current flow and voltage drops on a 5v regulator during integrity testing
  • Using an ohmmeter to ID the sensor ground circuit
  • How much current flow does a diode meter produce

Output Circuits

  • How to avoid time wasting, manufacturer flow charts
  • Integrity testing on bias and non bias circuits
  • How to recognize a 12v bias
  • Purpose of bias voltage
  • How to use bias voltage during troubleshooting
  • Ground side switched circuit operation and testing
  • Power side switched circuit operation and testing
  • Voltmeter and test light effects on bias voltage


In addition to the seminar on Saturday, attendees are invited to join Paul for a meet and greet/networking event on Friday, April 30.  Dinner will be served.

About Paul Danner

Paul Danner is an ASE L1 Certified Master Technician with twenty-eight years of field experience in electronic, electrical and drivability diagnostics. For nineteen years he has been employed as an instructor at Rosedale Technical College where he has taught Engine Performance Diagnostics and Electrical and Electronic Systems troubleshooting. Fifteen years ago he opened his own mobile diagnostic business which performs electrical and electronic diagnostic services for garages in the South Hills of Pittsburgh. The information gathered through this work in the field has enabled Paul to utilize up-to-date information and real-world scenarios to make his classes such a valuable resource for today’s technician. In April of 2011, Paul started filming his case study work in the field and began uploading these videos to YouTube, so his students could learn first hand the testing methods he teaches in the classroom. Paul says “My only goal in these early years of filming, was to simply make my classes better! I never had the intent of creating something for the world to see and learn from”. Now, these YouTube videos have lead to a global platform, with views and followers in over 150 different countries.

With the success of his YouTube channel, Paul decided in 2013 to start filming all of his classroom lectures at Rosedale Technical College and began uploading them to a members only portion of his website called ScannerDanner Premium. Paul considers ScannerDanner Premium to be his “global classroom” and has had the opportunity to see and hear about lives being changed from all over the world with his teachings. Please take a moment and read the feedback page of the website to see some of these success stories.

Paul is a proud graduate of Rosedale Technical College.
