You could have a toggle switch to go from "normal" to "leisure"...
Interesting problem here - although im sure with an easy solutions except i havent sussed it yet.
My parents have recently bought a VW camper van. I fitted them a new CD player. Its great and works well. However being fitted correctly you have to
have keys in ignition to make it work. CD player is fitted in conventional position in dash board.
Now the interesting bit, they use the van to go on holidays. When parked up its nice to have a meal and a glass or 2 of vino, whilst listening to some
music. With keys in ignition and consumption of alcohol going on this raises an interesting debate. So, what is the best way to wire up the CD player
with a seperate switch to make it come on without keys in ignition, but in such a way that if you forget to power it down it doesnt drain battery and
leave said van stranded? (whilst still leaving it conventionally wired for travelling) Im looking for ever so simple solution such as a switch that
has buily in timer, that say powers up CD player for 4, 6 or 8 hours etc then switches itself off, but can be switched back on by resetting it. Is
there an easy cheap solution that doesnt need small skills in designing electronic circuits and making it from scratch?
If you have a camper van how do you get round this challenge?
Thanks in advance,
Darren.

You need to run it off the leisure battery, that way while running the engine the battery is charged then when you stop the leisure battery is on
it's own so if it flattens it does not affect your starting etc.

Yes- seperate battery. Much simpler You could have a toggle switch to go from "normal" to "leisure"...
I thought of that and its a great idea. I was just trying to avoid running new wiring to the dash to make it a little simpler to wire up. Was sort of thinking of taking a permanent live feed through a timer switch and feeding it into the switched live feed. Ive not seen such a switch though and not sure what would happen if the switch is still energised and they decide to go for a drive (obviously on that occasion before the vino is popped open!)
To be honest though a radio will not draw too much to flatten a battery as long as the main bettery is in good nick.

If there's already a leisure battery fitted then the simplest solution might be to fit a 2nd CD player in the rear of the van. Easier to wire up, no worries about draining your running battery and easier to access when sitting in the back of the van too.

Split the feed to the cd player using a relay.
87a to the main battery ( battery side of the wire you cut,)
87 to the aux battery through your timer switch and link to 85
86 to earth
30 to the other end of the cut cd player feed.
Use this timer below ( you can set it to various times)
timer switch ( you may get a cheaper one
somewhere)
what you want is a relay to be deenergised after a delay when there is no music using a small microphone near a speaker - or sense signal to
speakers.
could probalby be done without major electronics knowlege.
If you want it simple then id wire up a permanant feed throuh a switch with a diode in the ign fed side so you dont back feed it. Then with ignition
off you can just switch it on.
But
I would wire it from the leisure battery so they dont get stranded.
what about fitting one of THESE inline with the CD player?
