I recently had to jump start my beloved x150, then replaced battery however ever since I have no radio cd A/C or touchscreen , I have checked all 3 fuse boxes and even replaced all relay’s but still no joy, looking for any help I can muster….. I have heard that if I disconnect battery for1-2 hours this will re-boot everything…… please help

 

You can also hold the two battery connectors together for 30 seconds which will have the same effect but much quicker.

Was everything working properly after the jump start? If so, we can surmise that is was something to do with the battery change.

I'm guessing that you didn't use a remote backup battery to keep the electrics live when you disconnected the original battery? I always use a remote battery with the Jag although it should not be necessary.

So many threads on this very situation. (Should we start charging a surcharge for wasted memory space ;-)

You may have replaced the battery… Did you replace with a rightfully sized, fully charged battery?
(incidentally, though a nice feature, having a remote backup battery is not a prerequisite and has no effect).

The first pinpoint test. Spell it out, please. What is the resting voltage on this new, rightfully sized battery?
Now that I touch on that, what is the size of this battery?
