Also spayed the underside with Carwell rust inhibitor. It's the second winter I'm putting this stuff on, and it seems to be working great so far. Stuff is good for rubber and electric components as well as for metal. |
Yep, 74 is the fuse for the telematic unit, which is the bluetooth unit for phone. It is a frequent cause of parasitic drain. Both times that it has occurred on my X was after an alternator death and battery drain. Replaced the alternator, charged the battery, but would have battery drain. After some research, I pulled fuse 74 and that solved the problem. I have seen disconnected and removed the unit as I wasn't using it anyway and I have now installed an AVin unit, so I really don't need it.
