Thread: Battery/Wiring problem - 03 Disco 2 TD5 in a coma

Last night, while adding de-mineralised water to the coolant expansion tank I spilled a little around the back of the tank on whatever loom is on the other side of that. Also a little splash went near the fuse box. Now I am having some SERIOUS issues. I tried the car immediately after and it failed to start, and I now have the three amigos. I used to be able to hear the fuel pump quite loudly, now it is whisper quiet. I can hear the starter firing rapidly but nothing happens - I guess no fuel in the lines. Sometimes when I try and start it the alarm goes off. I have done my best to dry up all the cables the water may have spilled on, to no avail. In fact, today when I tried to start it the dash lights aren't even illuminating - completely dead, as if the battery were gone. However, I can hear some sort of bizarre humming sound from the ABS area when the key is completely out of the car.

Where should I go from here? It seems more like a wiring problem to me - and not a battery/fuel pump problem.

Any help would be greatly appreciated.

Thanks guys.

How did you go?
Is it all up and running again?

Hi all - thanks so much for your help here.

Ran a multimeter over the battery today and found the voltage was at around 10, and dropped down to about 5 with lights on. Couldn't check the voltage while attempting to start it, as nothing would happen when I turned the key. I used a large marine battery from a friend's Landcruiser to test the car and it started flawlessly with none of the warning lights or alarm issues it was having on the old battery.

Suffice to say I went to Autobarn and bought a new battery.

Car is working as before, perfectly.

This thread was pretty sad given it was merely a bad battery.

Anyway thanks for all the help guys - hugely excited to have the disco in working order. Now on to the headliner for a Safety Certificate.

Thanks
Aaron.
