trying to charge phone on that plug... pls help.. TD

 

Not sure what a 97 Xj6 is in tin? If not a typo, the "youngest" cars here are ten years younger!!!


As the cigar lighter is a resistance unit, a 10 amp fuse seems puny.
but, that isn't the load you use it for. I doubt that any phone charger exceeds 10 amps.


The liklihood of all loads on at once is dim. But not impossible. Fr more than 10 amps, I would think.


That leaves one more probable flaw. A low grade short in the hot wire on that fuse


Good luck in following it through the maze. I'd be tempted to create a new source of 12 v for the fuse. True, a bodge to be avoided if possible.
Have I done it on a similar thing, In my case, not a short, but the absence of 12v.

You have a short, tedious to trace but throwing more fuses in won't change anything. As your '97 XJ6 is the X300 model, posting in the XJ XJ6/XJR6 (X300) section may yield more assistance on matters relating to your car.
