Default Re: I need HELP with my R170 not starting

WINNING! If you have charging issues read this! I found out that the small square black box in front of the heater valves on the passenger side is called a K56 and is a 125 fuse that links the alternator to the battery. That fusible link is solely triggered when an air bag is deployed and from what I have found they don't make the K56 anymore. I believe mine has been compromised which is why the car only had a handful of miles oner the last 5 years, just speculation on my part but I am installing a jumper while between the two terminals and I believe my charging issues are solved. Learn something new every day. Maybe when the system is working I will be able to clear the generic 7015 turbine speed sensor code, just maybe.

S I am connecting term 2 to term 3 with a jumper, am I not understanding the purpose of the 3 terminals? The R170 is the platform the XF is was built on and they have several things in common. That is why I am asking you guys for input. 30 days on this car, I need it to run and drive by sunset today.
