  • wat voltmeter do you recommend for a mechanic thats starting out

  • @meanpockets Yes. It's a great channel.

  • @jjenson2006 Couldn't agree more - you don't need any of that expensive stuff to fault find on a car. All you have to do is understand the basics of how the engine works and what parts are for! A lot of modern cars give fault codes which show which sensor has identified a problem, but you still need to understand WHAT causes that problem. That's what catches a lot of "new" mechanics out - they change the part the fault code refers to without realising what is wrong. Experience is valuable!

  • I'M SURE IF ANYONE OF THE HATERS POSTING HERE COULD AFFORD THAT TOOL THEY WOULD BUY IT IN A HEART BEAT!! I HAVE THE SAME TOOL AND IT CUTS DIAGNOSTIC TIME LIKE CRAZY, GREAT VIDEOS SIR KEEP IT UP!!!
