Battery problems sort of sorted

Hi have been following and joining in the saga of discharging batteries. Having exhausted all the suggestions on here and having to resort to disconnecting the batt every time I stopped it was time for an auto electrician.
He found 1/ Battery was u/s
2/ all circuits thta should switch off on turning off worked
3/ current drain is coming from drivers fuse box fuse 17.
Their trade book lists fuse 17 as module!!
our hand book lists it as electronics.
Fuse box is dry, so what does fuse 17 control? and is it replaceable.
Total cost for 5 hours work and new battery £90 which i am happy with.

well being multiplex wiring fuse 17 covers a few things TIS lists fuse 17 covering
instrument interface control
diagnostics interface
Turbo diesel models engine control
Charging system
Central timing modual (most likely)
Pats
cigarette lighter
clock
Air con with SATC (again likely)

Thanks for that (I think  ) did not think it covered so much, what suggestions do you have if any? what would you replace? Need to sort this as with the rain in N Wales it is not fun playing with batteries.
Why timing module? if all is turning off
Why aircon?
Dont doubt you just like to know these things

A OBD scan would tell you if a modual is at fault
i said those 2 as process of elimination
im assuming you have no issues with the instruments, (flicking dials would be from dead battery), lights not working, other lights working when one should be lit, bad earths sort of thing, dials randomly working
Pats, well if this was playing up you could have starting, cutting out probs,
clock draws such little current that i doubt it would drain a battery between starts
yours isnt a diesel 
unless you have the cigarette lighter out then i cant see something shorting it, plus if it was shorted you would smell the wires melting
SATC panels can burn out, if the little lcd screens crack the liquid is corrosive and could eat at the PCB board
central timer, used every day, its essentially a relay with some extra bits, contacts can burn up, not having stripped one i can only assume the timer part is a chip of some kind, perhaps a 555 chip
though thinking about it the charging system could be a culprit, have the alternator (diode fault? )checked,
What i would do it pull the fuse, start (or try to start) the car and see what's not working any more,
other then that, do you have anything like a mobile phone charger fitted to the dash, if that was hard wired in to the cigarette socket wiring, somewhere and become faulty then that would kill it

[i] no problems with instruments, and as you say flickering dials are batt problem, they now gone[/i]
Pats, well if this was playing up you could have starting, cutting out probs,
[i[color=Pink]][/i] other than flat batt no starting probs, she fires up great[/color]
clock draws such little current that i doubt it would drain a battery between starts

[[color=Yellow]i][/i] No 24V cossie[/color]
unless you have the cigarette lighter out then i cant see something shorting it, plus if it was shorted you would smell the wires melting
[i][/i] not had probs with ciggy lighter
SATC panels can burn out, if the little lcd screens crack the liquid is corrosive and could eat at the PCB board
[i[color=Yellow]][/i] again all seems fine there[/color]
central timer, used every day, its essentially a relay with some extra bits, contacts can burn up, not having stripped one i can only assume the timer part is a chip of some kind, perhaps a 555 chip
[this is one that sparky thought of, although all systems turn off. [/color][/color]
though thinking about it the charging system could be a culprit, have the alternator (diode fault? )checked,
[color=Yellow][/i] checked when he went through the system yesterday[/color]
What i would do it pull the fuse, start (or try to start) the car and see what's not working any more,
[color=Yellow][i] will try that if it ever stops raining here[/color]
other then that, do you have anything like a mobile phone charger fitted to the dash, if that was hard wired in to the cigarette socket wiring, somewhere and become faulty then that would kill it |
|
 [i][/i] Have a proffessionally!! installed hands free but dont seem to have probs with it but might be worth looking at.[/color]
Thanks for input, really hope that I can solve this one.

Spoke to sparky and he confirmed that they have carried out the checks on alternator and pulled fuse 17 so it looks as if a swap of the timer module is next
