I am the owner and chief technician of a fitness equipment service company. I would like to learn how to bench test and repair the electrical circuitry that controls the fitness equipment. Can anyone suggest a path for me to take to learn these skills? Any reply would be greatly appreciated.
Thanks

 

You need to learn power electronics.
If you donno basics, then you should start with it first

 

What part of the world are you? I would suggest a basic DC course to get you started, and work your way up.

If you are a major self started we have a text book on the top of the page, you can use that and then post questions as you run into them.

 

There are links to our E-books at the top of every page. They are a very good place to start.

If you want more in-depth knowledge, I recommend the Navy NEETS modules.
You can access them for free, here:

Skip Module 6. After Module 9, you can pick and choose those you'd like to read.

The test equipment module is generally handy. It would be a good idea to pick up a decent O-scope. You can find used O-scopes on auction sites. Tektronix is a very good brand.
