More current drain
 

OK, so a few weeks ago, I solved my current drain taking out the aftermarket GPS tracker unit, from behnd the rear seat.....Hurrah.:icon_biggrin:.
3 weeks later, the battery went flat as a pancake again.....Argh :icon_eek: So doing the fiuse measuring trick, I found the currect drain after shut down, was the fuse called PHONE!
A 5 amp fuse..in the passeger side fuse block..ho hum, As the radio fuse is a separate 10 amp fuse !
However, this also stopped the radio working..But then back to 30ma draw after shut down..Perfect!
So Any ideas on the link between the two, and can we remove or unplug the phone part somehow?
As enjoy the radio, and will never use an ancient phone!!

Disconnect the alarm back-up battery in the right fender well under the headlamp. It shorts out with age and causes a constant drain as well as other electrical gremlins. Noticeable change in battery voltage drop over time when the vehicle sits unused. It even interferes with a battery maintainer.

Yes thank you :) , I did that last year, on a quest to find the original drain!
However, yes I must try to interpret the Radio/Phone link

Just wondered if any one has successfully separated them?

I think you first of all need to have a look at the wiring diagram to see what is supposed to be on the telephone fuse you pulled. As far as I know the radio and phone should have completely separate fuses.

Check the wiring diagram to see what fuses supply the radio and which fuses supply the telephone.

I knew the telephone module is located somewhere in the trunk, because I saw an XKR, when I was looking to purchase one, where the module has been removed due to a battery drain too. Mine has no telephone fitted.

It's in the cabin, behind the back seat.

I'm sorry, I didn't know that. The man who sells the car told me it was in the trunk, it was a 4.2. May just unplug the connector be a solution? No need to remove the fuse..

2000EG shows its location as in the trunk/boot:

..but it has moved around. Under the centre console in my car.

Odd that the radio is affected:- the two 5A fuses(one ignition (i) switched) are shown as dedicated feeds.

I'd forgotten about the StarTac flip phones that they used before the later fixed phone with a curly cable. I had one back in the late 1990s or early 2000s - it was a cool looking phone, but I found mine had terrible reception. Maybe that is why Jaguar moved on to the fixed phone (and ignored Bluetooth of course).

Aye, these:

Still working - at least until 2G goes the way of the dodo...

A trip down memory lane with those old things - as you said the main benefit being no Facebook.

I've thought about repurposing the wired handset in my car into a Bluetooth handset - I'd never use it, but the novelty value would be great.

So after all that I looked at the circuit diagram and see the phone just plugs in to te radio, so I will try and disconnect it and see if all is well!, Logically yes the 5 amp fuse supplies the phone only and the radio has its own 10 amp fuse, so definately worth a try!
Has any one else disconnected it?

Helo all once more, so finally had the radio out and rear seat....
So it seems that the 5 amp fuse on passenger door side (RHD) is the rado not the phone and the 10 amp is the phone ..
So after removing the GPS tracker as above orginally all was great for a month, then it started again..Grrr :mad:
So after more investigation I determined that the phone was now draining the battery..
Anyway after checking the radio it was fine, I actually unplugged the phone behind the rear seat, removed the phone module, taped up the connectors, so as not to rattle..
But note do not remove the yellow connector on the radio(nor between the seats under the arm rest) as they both inhibit the aerial rising, and low and behold no battery drain once more.. Hurrah..
