Flat Battery

[g8dhe]

I have put the charged L/B back on the vehicle and did same test as S/B
reading obtained 0.38

Hum, if that was 0.38 Amps then its worrying, as that would typically flatten your L/B in about 6 days on its own and nothing else should have been drawing current. You need to identify where that current was going. With no charging taking place the feed from the split charge relay should not have taken any significant current, with everything else OFF then where was it going ? You need to follow the cabling back or double check with who ever installed the split charge relay and battery what else has been connected to it!!

I refixed the charge lead from the relay started up and got 14.35 v into both batteries then ran out of diesel!!! Will I need to bleed the fuel system?

For info, my Zig unit is the basic distribution box/voltmeter (no charging) At the mo I have 12.30v in S/B

and 12.83v in the S/B. I will monitor the drain over the next 24 hours and report back

OK, well I expect to hear that the L/B is showing a lower voltage, but if you do any runs in the vehicle it will be difficult to tell - mind you with no diesel you won't be going anywhere!

Hello Mr Spout Here!

We've only had our Bongo for 2 weeks now, and for the last week it's been sat on the drive whilst we've been away. And we've come back to a completely flat battery (no idiot lights on the dashboard even) .

I'm no electrician but armed with multimeter I've found a drain of 0.2 amps. Is this enough to drain the battery over 7 days?

I was interested to read that the remote/central locking might be a possible source of current drain, because our central locking doesn't work as it should. How can the locks use juice when not working?

I have disconnected a DVD screen (mounted in the dashboard) and reduced the current drain to 0.08 amps. (So half way there!)

I'll report back when I've isolated the central locking.

We have joined the club, and so, "thanks" for the fuse diagrams (pity I'd been pulling fuses and trying to see what was what for 3 hours before I looked to see if they were on here )

Further investigation:

The 0.08 amps drain can be reduced to 0.02 amps by pulling the 40A fuse under the bonnet (BTN). And the remaining 0.02A can't be traced through any fuse. Some future investigation needed there then

I then went to the fuse box inside to try and find where the 0.06A was going. Turns out to be fuse No1 "cabin" using 0.05A. Seems to do interior lights and electric blinds. Looks like we'll have to do without these for a while.

So with interior fuse No 1 disconnected I'm left with 0.03A drain for the time being. Hopefully this wont flatten the battery too quickly.

I had a problem with the battery going flat and it turned out to be the fluorescent tube interior light. I posted the problem on the forum and somebody asked if the light was dim, which it was. It seems that, when the tube is failing, it can cause problems - a new tube and the problem was cured
