Great video! One thing that I came to learn the hard way is that 12 volts read on the meter is not the same as a 600-700 milliamp test light lighting, specially on the starter circuit.
That's called a voltage drop and why open circuit testing is no good! I am wondering if the shop had tested open ckt and those wires were barely touching/ still connected mechanically?
Man I thought you bounced from RU-vid. Do you have many bugs in your phoenix plus scanner? I got one and it seems buggy like identifying cars sometimes
