| Looking for a Power supply but only when engine is running. |
|
As tiltle says I am installing a second battery and looking for a power supply to charge a relay that connects the batteries together but I only want this when the engine is running.
The LR Warn winch only gets power with the Key in position 2 and the remote connected.
I just want power if the engine is running prefferably under the bonnet.
Any ideas?
Thanks Roel

Where else eould the engine be running?  I believe that every human has a finite number of heart-beats. I don't intend to waste any of mine running around doing exercises.

I have plenty of power under the bonnet as I have a V8. What I am looking for is an electrical power source to switch over a relais that connects both batteries.
Somebody here will know, I hope. Roel

Will ignition on rather than actually engine running do? If so just use the ignition feed from the fuse box to the winch solenoid under the battery to trigger your relay The End

I think the compressor only works with the engine on not sure if that is a signal or 12V. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

Is it possible to get a signal to activate a relay from the CANBUS? “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

yes, but it's more cost-effective to use a VDR as above

Would there be a signal for when the DSC is disengaged? “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

one of the two relays in the n/s boot will do the trick, on a disco 3 its either the red/white, or plain red i think but check with a meter! (assume its the fuel pump relay!)

I found one under the bonnet for mine. In the main fusebox by the battery. I used a meter to test them all with engine off (ignition on) and then again with engine running. Can't for the life of me remember which number fuse it was though but there definitely is one.
