Ahh, OK.  A mains TV running from an inverter is a different proposition. Much more thirsty.

Good point. Or take your battery charger along and ask them if you can plug it in somewhere to charge it up.

I'd be surprised if a 110ah battery didn't last you the whole holiday though.

I'd hope a 110 ah battery would run it for a whole week! If it's a 12v powered TV rather than a mains set on an inverter it should only take 1 or 2 amps at 12 volts.

The capacity of the battery doesn't really come into it.
.. within reason, of course. If you set off at the start of every journey with a completely flat 110 ah battery in the boot I think the alternator would get the hump, but it's more down to how much charge you're going to be taking out of the battery than its capacity, and that depends on the application.

Wouldn't the alt be overloaded with charging a 90-110Ah battery...?

The capacity of the battery doesn't really come into it. The alternator should current limit at a safe level so the more battery capacity you connect across it the longer it would take to charge it. Furthermore, if you use a caravan charging relay you'll only switch in the second battery when the main vehicle battery has fully charged and the alternator is powering the loads on the car with capacity to spare.

Depends if the battery is going to be permanently mounted to the car or if it's just a temporary arrangement and also how quick you need it to charge. In addition, if there's going to be load on it during charging.  For a permanent installation I would run a decent, thick cable from the car battery through a fuse to the rear of the car, with a caravan split charge relay or similar to enable charge to the second battery when the car battery volts rise.

You want to drop as few volts in this cable as possible because if there's too much drop the battery won't reach a fully charged state. If you need to draw load from the battery during charging it might be wise to take this from the end of this cable at the front of the car to minimise voltage drop at the battery end.

For a temporary set up, something to plug into the cigar lighter may do the job, depending on the voltage at that socket with the other loads in the car drawing current. You might find the lighter socket delivers insufficient voltage (less than 13.8 and the battery won't reach full charge) to charge the battery. You may well find that the resistance in the circuit is enough to prevent the current getting excessive, since the battery "looks" like a voltage source of up to 12.5v with an internal resistance. This means that you're only dropping a volt or so across the resistance of the circuit instead of the full 12 volts - unless you start with a totally flat battery, of course.

If it's a temporary lashup and you've got an inverter and a battery charger handy it might be the easiest solution. At least you know the charge to the battery will be under control.

Noticed the updated version of firmware has settings in IE to disable pictures so may give that a go.


Updated version of firmware won't talk to my wireless access point ::).  Back in the drawer with that then.. >:(

You probably noticed another idiot acessing it with a PocketPC. Came across my old one and tried.. Not a total success. Once all the pictures , etc. had loaded I had about 1/8th of the screen with the posting text in!

I couldn't help but notice at the weekend that the "satan tractor" was parked relatively close to your leccy meter. Could its' curse be spreading?

The 535 was basically getting worn out - he does intergalactic mileage

Don't tell me he broke all of those and the Renault 19 was reliable?

I think the Jaguar system was cobbled together after they were bullied into using the Ford parts bin to avoid the shame of making a front wheel drive car - not that they avoided that for long.

It goes without saying that a 2wd transmission has a handy torque limiting device namely the traction available from 2 driven wheels. Double that and you have to think about the torque rating of the whole transmission again. Bolting a bodge onto a FWD gearbox might have kept the beancounters happy but I suspect this car has become a victim of that decision.

XJR looks much more interesting. I was given a rather rapid lift across Munich in one of these a few years ago and couldn't believe it was "just" a V8. It had all the refinement of a V12 jag and was seriously quick. It'd still be a brave man who took that on, though.

At least the "known issues" with the Omega, Rover K series, etc are rarely terminal and replacements are easily sourced if it comes to that.

Trust me, still take a spare crank sensor

Mmm. Mine's 2 weeks old now. And shortly heading on a little journey too :-/

I've always preferred night / low light photography. You can get some stunning shots when you get it right.

Doesn't seem long at all. I wonder what proportion are "active"?

I'd like to see him accidentally shut the windows and sunroof with the turbine running! Reckon the car would implode ;D
