No news to me, boy.

He's probably as old as you.

He isnt.

I've met Bod and he's (I'm about to insult him most likely) very
very
old
indeed. I'd have to guess 80 to 90.

Thats just the furious drunken grave dancing and flagrant drug
abuse.

Smoking does make your face more wrinkly, but I'm sure he told me his
age once.

For some reason I've always assumed you're about 70.

You're still wrong.

What is your age then?

And back on topic, I just bought a 16 amp 13.8V power supply, that
ought
to keep the bloody frog car charged up. It's currently maxing out my
2.5A supply all night, and still not starting in the morning.

That's telling you your battery is knackered. Try a high rate
discharge
test on it. You will see it fall over very quickly.

Wrong yet again. I've changed the battery twice. It's consuming power
overnight - presumably the alarm - I've actually measured up to 4 amps
(randomly, sometimes it consumes nothing) coming off the battery with a
meter when all the fuses are pulled.

Sounds more like a wiring fault. An alarm shouldnt
ever take anything like that when its not sounding.


But if it's broken....


There is no fault in an alarm that would produce a result like that.


I don't know enough about alarms to disagree, but couldn't it be sounding the alarm without noise as something is broken? It's never tried to prevent me starting the engine though.

Can be a real bugger to find if its a pinched wire somewhere if it isnt
obvious where a wire can be pinched like at one of the doors etc.


Surely a physical short like that would just burn out eventually.


Nope, 4A isnt enough to do that.


I can't see a loose wire doing that. At some point it will either burn itself or a fuse. It's been doing it for 3 years. 4A at 12V is 48 watts, a lot of power. Think how hot a 48W bulb gets.
