First time user!
ScannerDanner uses a Power Probe for the first time. At timestamp 10:10, ScannerDanner uses the Power Probe 4 to energize the starter to confirm his diagnosis.
















ScannerDanner uses a Power Probe 4

ScannerDanners works upside down and uses Phil's Piercing Probe to gain access to a solenoid and then uses the Power Probe 4 to test if the driver is good. He keeps his thumb off the switch and offers a stern warning, "If you do this wrong, you're gonna cook the computer...Do not put power on this control circuit to the computer." This video relates to Section 3 of his book, Engine Performance Diagnostics.



Why does ScannerDanner like using the Power Probe 4?

"Starting to become a tool of choice because... I don't have to find a good ground or power, I am already connected to the battery." This video relates to Section 3 of his book, Engine Performance Diagnostics.
