Hi, I bought a 4 channel scope last year and went on the training course and that's about it! I can remember some parts and obviously the more I use it the more I will learn, please go easy on me
I have a Ford Focus with a Charging problem (smart charge), the customer drove it in with it cutting out and no power steering as the battery was flattening, I have searched for information on these as we always have problems that appear to alternator but always turn out to be wiring/ plugs etc.
I've disconnected the plug from the alternator and checked the charge rate as a conventional system and it read 13.7v, from other forum post's that seems fine and means the alternator is fine?
So my question is can anyone explain the set up on the scope and what wave forms i should expect by back probing the back of the 3 wires on the plug?
