I hope someone can help with my problem, 2006 Accord 2.2 Diesel Exec Tourer.

When leaving  my car unused for a couple of days the battery is well drained down & won't start sometimes. The alternator is charging fine, Battery is only a year old so no trouble there. I tested for a drain on the battery by using a 3w bulb wired between the battery post and the battery cable (disconnected). The light bulb was lit which shows current being used, I then removed each fuse from the interior fusebox in turn until the bulb went out. It went out when fuse No. 7 was removed, according to the handbook this fuse is for back up, ( I assume that means reverse lights). The reverse light is working fine, I disconnected the bulb but still had leak off.Has anybody got any idea what could be using current on this circuit?  I don't know if it's related but the HFT and the power socket in the centre consul stopped working some time ago, also I fitted a reverse camera years ago, that's working fine. I also checked for leak off with the HFT module disconnected and that made no difference. Any help welcomed..

Had a very similar issue just last few weeks. Disconnected the Bluetooth module and not had a problem since

Mine had battery issues after fitting parrot. Lots of battery issues have been affected by Bluetooth modules. Saying that tho, if you don't have a Bluetooth fitted, you'd be back to square one!

I realize now that fuse 7 named as "back up" does not mean reverse lights lol. I did disconnect the bluetooth module behind the panel where the hazard light switch is but there was still a drain on the battery. Tomorrow I will leave fuse 7 out and see what doesn't work

I’ve been trying with mine for five years. I always carry a spare battery. I find it’s not quite as bad if I turn the air con off. It has had 3 alternator and 3 batteries

Same here, though I also carry a small set of jump leads, saving swopping over the ******* thing whenever it wants to play silly ******s.
