Default Battery Draining

Hello,

My battery keeps on draining, it is a new battery with a new Alternator....BUT when i have the car all tunred off and when it is very quiet i seem to always hear a clicking sound on the left side of the hood. The clikcing sounds comes every 45 seconds to a minute and i suspect that this is what is draining the battery.

I have my Three Amigos lights tunred on, i also have my SLS light turned on since i switched my suspension to a Coil from the self leveling system.

Is it possibble that the clicking sound is coming from the three amigos or the SLS light when the car is fully turned off which is then causing my battery to drain.

Also, i had installed a Remote start a few months ago...i hear they say that remote starts can mess with the electrical system.

I hope i can pick your brains with this.

Thanks,
Gerard

Most likely remote start. Clicking could be the ABS, normal to a point. SLS parts left behind can try to level truck when key is off. See attached wiring diagram, note that three valves and pump share same ground point, valves get battery power from SLABS. See that coomon ground point is C0811, separate pix attached for that. Take it off and tape up and valves can't draw power. Other wire (C0810) is fuel pump, you'll know if you took off the wrong one. You can also attach an amp meter or just a test light in series with the (+) battery lead, high current drains will make test light glow. Pull fuses untill it goes away.

Thanks Savanna Buzz...this will help....I do think it is some kind of ground thing just as you suspect.

Thanks,
Gerard

@ Savannah: I failed to mention: My three amigos lights are only on sometimes say 50% of the time so it still works half the time.

If i remove the ground C0811 will this kill the shuttle valves permenently thereby not working at all.

Thanks,
Gerard

Those valves are for the SLS lift that you said you removed. Just happen to be a sub-function of the SLABS

Did you disconnect all of the connections at the SLS pump when you converted to coils? Or better yet, you can have someone with a testbook or hawkeye turn off SLS in the BCU. i'll bet this is what is draining your battery.

@ Savanah,

It worked...i removed the CO811 ground and the clicking noise is gone and more importantly my battery is not draining anymore.

Your advice saved me $$$ and having to go to the shop that installed the remote start. Good to know it's not the remote start.

Thanks,
Gerard

I registered just to thank you fine gentlefolk.
My ladies 99 Land Rover Discovery II has been having the exact same issue. The "wonderful" mechanics told her the clicking was nothing and wasn't the source of her draining battery and would persist for the life of this vehicle. After reading this and seeing the diagrams, I removed the same ground and 2 hours later still no clicks and her battery is still running strong.
This has been an annoyance for months and was causing her to hate her Discovery! Thank you so very much!!!
