Hi,

Recently fitted a Wilinton kit to run Radio, Blinds & Interior Lights off the liesure battery. Since this modification my radio is loosing the preset staions whilst switched off. The LB is not dropping voltage as it is maintained by my solar panel & is in excellent condition. Have I got a fault on the radio that has just coinsided with the kit being fitted? Or could this be to do with the installation of this kit and the way the kit runs the radio off the LB?

Cheers

Sound like you may not have the constant live (memory) feed connected.

this feed usually stays on the starter battery side

I would concur with teemal.

Fuse one not only serves the cabin lights but the radio memory.. ( i think it serves the ECU as well??) I would be looking for a continuity break along these lines.. Possibly an "in-line" fuse to the radio in the iso connector immediately adjoining it at the back of the unit????

I have the same problem, presumably as a result of switching it over to the leisure battery. Can't be a*sed to fix it since I use the radio so little, but it is annoying. I'd be interested to hear of a quick fix for a lazy incompetent clutz like me

Try running a temporary fused lead direct to the leisure battery. If it solves the problem wire it up properly.

To clarify - radios have two live feeds. One is permanent 12v - this powers the radio's memory and keeps your presets. The other 12v feed is ignition switched - this one turns your radio off when you turn the ignition off.

The permanent live is also the one that usually gets put under the full load to power the radio's amplifier. The ignition live is just there to tell the radio when it should be off.

It sounds very much like you have connected the 12v switched live feed to the battery (leisure maybe), and not connected the permanent 12v live cable to anything.

I'm assuming (because it worked fine before) that whatever has happened to mine will be due to the jumpers that move things like the radio from the starter battery over to the leisure battery, so that the radio can be on even when ignition is off. So the question I guess is what should now be used to switch the wire known formerly as the ignition live? TBH I can't be bothered yanking the unit out to do it given how little I use the radio and how quick it is to tune it when I do, but this is v useful info for those who want to tackle it.

The easiest way is to select a radio that does "Turn off", you will find that radio's with remote controls are much more likely to have this, and of course a needed feature when sitting in the back of the van!
The feed that draws the most power varies, sometimes it is the switched lead sometimes its the permanent feed normally the only way to find out is to measure it, its not a parameter that often appears in the Specs.
