    :Hi,
    :
    :> like a headlight, heated rear window, electric window motor, air con fans
    :> running.
    :> Its not going to anything like radio memory causing it.
    :I agree. All of these are visible or audible (fans, lights...) excepted one
    :: remove the bulb(s) used for the trunk lighting. It may be a cause, and it
    :was a common fault with some people : they go fishing, leave the boot
    :eek:pened, and in the evening, when they try to get back home, no power.
    :
    :HTH,

    Either a fan or headlight remaining on would be easily detectable but a trunk
    light would not be so evident. On the 307 the rear seats fold down so it would
    be easy to check whether a trunk lamp was permanently lit. Even if it were a
    trunk lamp it would take at least a few days to drain the battery, particularly
    where the vehicle is being driven periodically.

    I had a sedan once and a small panelbeating job had to be performed which
    involved adjustment of a trunk support strut. The repairer used an oxy torch to
    soften the strut to bend it before repainting the strut. He checked his
    adjustment by shutting the trunk immediately after the heat treatment and when
    he opened the lid the lamp was on as expected. But he failed to notice that the
    retained heat in the strut had melted the nylon plunger on the trunk lamp
    switch. When he closed the trunk lid again the plunger could no longer open the
    switch contact and the lamp remained on permanently without anyone being aware
    of this fact. It took about 8 days for the battery to go flat and I thought it
    was just the battery getting a bit old. I recharged the battery to get it
    started but again it was flat within a fortnight. Only then did I start some
    checking by measuring the standing current drain on the battery. It was over
    500mA (6 Watts), which was abnormal, so I did some checking for lighted lamps.
    When I opened the trunk and felt the bulb immediately it appeared to be
    excessively hot for only being lit for a few seconds so I checked the switch and
    saw that the plunger was completely melted away.

    Hi Lenny. This is top posting. Now scroll down to the bottom.


    And this is bottom posting. Newsgroup etiquette is that you always bottom
    post so that the story flows and all postings finish up in sequence.

    Sorry to hear about your unnecessary expense on a battery. I really think
    you need to go to an autoelectrics specialist. If you are anywhere near
    north Surrey or south Middlesex, I can recommend Roy Autoelectrics in
    Hetherington Road,Charlton Village. Otherwise I think you need to use your
    Yellow Pages and find one. Good luck.

    The Heater Plug relay(attached to the outside of the under bonnet fuse box,
    just behind the front bulkhead) had burnt out. Replaced this and the car
    stopped loosing it's battery power over night, the warning light went off
    and the power came back again.

    Did you find the cause of the problem by your own endeavours or did the garage
    find it?

    The garage certainly didn't find anything. A friend recommended a mobile
    auto electrician/mechanic who found it in 10 minutes.

    I thought as much. Going on your description of the fault finding ability of the
    garage "mechanic" (?) I would have been extremely surprised if they had located
    the fault themselves.

    Not yet, If past experience is anything to go by. Lets give it a week and
    see what error light appears next because you can nearly be sure one will.

    The car runs very nice when it is working properly though.
