Big Problem Battery Goes Totally Flat After 2 Days
Posted 27 January 2013 - 03:13 PM
I charged it up overnight and went out in the car the next day when i indicated right the warning buzzer from the towbar set up was sounding although i wasn't towing anything !! I investigated and found the boot carpet soaked and the wheel well in 2" of water. Tried the pouring water over the boot shuts but couldn't see it coming in. I then found the boot latch loose so i set this up sealed the light unit mounts with copiuos amounts of vasaline and removed all the wet articles. I then removed all the wiring for the towbar and thought this would be it. Charged it up and ran around as usual but no .... 2days and it was totally dead again ???!!!!!
Any ideas of common faults or what to try next would be gratefully appreciated. I have had a meter across the terminals and it is charging at 14.2 Volts and ok when under load i.e. fan, lights on etc. Can't see it pulling anything when the ammeter is on it either. Getting really frustrated with it now !!!!!! I feel a gallon of Super Unleaded and a Zippo coming on :-(

It's not got the Yuasa one on at the minute it's another make i'vre not heard of before.
Another thing to point out is the auxillary belt and tensioner have been replaced after the Bosch battery failed as the ECU apparently can play havoc with the charging if the belt is slipping just wondering if there is something that fails regularly on Focus' that could be pulling the battery down.
Iv'e just put it on charge for the night as it is totally dead and the charger has an old style ammeter on it and when put on rapid charge the meter is flicking between 4 and 9 amps as though something is intermittantly pulling current, i'm wondering flasher relay but surely the indicators would be flashing ?? Is there anything else on these that pulse a relay intermittantly ??

from yausa reference the elite series Ultimate Expanded Calcium Technology
Ultimate expanded positive grid plate technology utilises specially rolled (wrought) Lead/Calcium/Tin (SCS) alloys and developed plate manufacturing process to give the optimum automotive battery design.
The wrought expanded grid process gives a significantly stronger and smaller grid grain structure than comparable cast calcium-silver alloys. Yuasa’s innovative plate manufacturing and formation processes are essential in maximising the benefits of Expanded Calcium technology.
it does sound as if you have a drain somewhere
