  1. Hi, I live in Winnipeg, manitoba , canada. I am a red seal journeyman truck transport mechanic. I worked for many years in an international dealership, i always struggled with electrical and a dealership environment doesn’t help that, I would get stressed and avoid it at all costs. I became very good as an engine mechanic so I wouldn’t get electrical as much. I started a repair shop and grew it to 8 employees before selling. I have a lot of respect for you as a teacher and an entrepreneur. I took 4 months off after selling my business and decided I would finally try to learn electrical in my garage on my own time no pressures. I bought your book and leads, they are a god send. I have since convinced 3 of my friends to buy your book and leads. Without sounding cheezy you and your systems have changed my life, I am still learning but I am the electrical guy now at work. I am going to buy your cards as well.
    Take care, thanks eh!, lol

  2. I work for a municipal garage on heavy equipment. I’ve been using my loadpro leads for about 2 years now, and they are great. We have a huge amount of corrosion caused by road salt. My loadpro leads have cut my diagnostic time in half. Thanks Mr. Sullivan.
