Leisure Battery Wiring with relay - ciggie working not radio
Posted: Tue May 15, 2012 10:34 pm
Hi, I've read so many posts on this and I have figured most of my issue out I just need some confirmation my understanding is correct and the best way to proceed.
The problem:
A couple of years ago I paid an auto electrician to wire up ciggie and stereo to feed from the LB via a split charge relay. I figured out recently that only the ciggie was connected this way, the stereo continues to run direct from the starter battery at all times (yes I found out the hard way).
So what I want is to add the stereo and the blinds to the LB relay (along with the existing ciggie), so that these 3 items all run from the LB when the engine is OFF.
The set up currently is as follows (using the relay numbers and bongo fusebox diagram for reference):
Relay:
87 - brown - to Leisure Battery and ciggie (spliced into the wire)
86 - yellow/green - earth
85 - blue/white - connected to the lower slot of fuse 8 in the cabin fusebox - I assume this is the ignition trigger feed for the relay.
30 - Blue spliced into red/white which is connected to the upper slot of fusebox position 4 - I assume this is the main battery.
The original wiring into 1-5 (white/red) and 6-8 (red/black) appears to be intact.
According to the bongo fusebox sheet, Fuse 8 should be ciggie, mirrors and radio, but in my case I can remove fuse 8 and they all still work - so I am assuming that this is simply now providing the ignition trigger to the relay. I've found the stereo is actually connected to the lower slot of Fuse 1 along with the cabin (lights etc), it must be spliced into the cabin wire somewhere...
This is where my sparky skills cease to exist. I've seen several solutions for non-intrusive patching which look good, but since I already have a 'custom' set up I'm not 100% sure how to proceed.
I have a few photos up on my google+ account - https://plus.google.com/photos/11021624 ... vD-lbnUmQE
If anyone can advise how best I get the stereo and blinds running from that relayed LB when engine is off that would be very helpful, thanks.
