Quoted from tonyf1965:I think part on, the sticking magnets/ on to long. Check your software version when you first turn it on. Newest software is about 14 eBay, from Canada. Also I would test those magnets with an ohm meter. They should all 3 test the same. I am guessing 5 ohms. Any lower than 4 probably shorted bad magnet, any higher than 12 ohms probably bad. Marcos sells them. The buzz noise that electromagnet is just loose. Welcome to the club!
Thank you! Going to take another look.
