As title guys, the battery drains overnight, I’ve charged up a few times and topped up the water in the battery, once it’s charged it’s fine starts up straightway, I can use the Can through your the day no problems, But once I parked it up, The next day it doesn’t start and battery is flat, so I thought a drain that is causing the issue so I started checking for a parasitic draw and found that fuse 29 20amp Storage Link is running even when everything is turned off, thing is storage link controls apt of things so how to find out what’s causing the drain, I’ve taken fuse out and I’m Going to check in the morning to see if the Cab starts,but if storage link is the issue then how do I find the cause as it controls the radio lights central locking and maybe more things.

TX2 2006

Thanks is advance

Battery is showing 12.7 and when I start the cab it’s shows 14.6 so battery and alternator seem to be ok, especially as the Cab started without any problems this morning, I pulled fuse 29 “storage link” and left it out overnight, so I’ve definitely got a drain, pulled all the fuses one by one and nothing changed until I pull out the storage link fuse, thing is that controls a lot of things, also fuse 40amp which is located on the inner wing near battery when I pull that out test light goes out.

Thanks Mr T,The Battery is new only about 4 weeks old, when I pull the fuse for storage link the next day it starts fine with no problems, I’ve had it checked by electrician and there is a draw of 0.006 which shouldn’t be enough to drain the battery, alternator is charging the battery at 14.6, and cranking is 11.07. I could get another battery but the same thing will happen again after a few weeks as the reason for the new battery the old one died probably because of this same issue.

Just an update
New battery installed still struggled to start next day but started
Alternator checked showed ok and charging the battery
Starter checked no issues there either
Drain test done and Taximeter/Clock fuse showed a drain of 0.036
Radio-PATS-CCU fuse showed a drain of 0.02

The old battery I took off has been sat in the shed for a couple of days, checked it with multi meter and showed 12.86v so that has not drained and I’m presuming that the battery is ok.

Now the question how to sort out the Taximeter drain, I will try and take the fuse out tonight and see if it starts the next day
If that is the problems ie drain how would I sort that out, read somewhere that the meter has relays that malfunction but didn’t say where theses are located, would they be behind the meter or near fuse box.

Thanks
