Battery Disconnect on Milano

I have a slow electrical leak that kills my battery every couple of weeks if my Milano is not driven. Have not been able to figure it out, so thought I'd just install a battery terminal disconnect like I have on my other Alfas. Like this: http://www.amazon.com/NOCO-ID220S-6V.../dp/B006EH9WUC.

My question: Will disconnecting the battery often wreak havoc with the ARC?

One thing which can help is to pull the radio if it is original, or pull the fuse if it is not.
Radios can drain the battery down because of the always on memories.

Yeah - thought about that. It has the same (aftermarket) stereo as my GTV6 and I don't have the battery problem with the GTV6. So I just sort of ruled it out based on that...perhaps erroneously. I should pull the fuse to double-check it.

Yep. Any ideas you have on what I should test are appreciated.

You need to measure the current drain with everything off. Set your multimeter to amps, disconnect the negative battery cable, and put the meter inline between the cable and the terminal. Should be maybe 25mA...significantly more than that and you've got a drain.

If you have a drain, you can pull fuses one at a time to help determine which circuit it's on.

Thanks for the pointers Tom. Electricity has never been my strong suit, so this helps.

It's the NEW Radio! Had a problem with my Race Car. New Radios draw ~100ma and over a long period the battery is not capable to start the car. 2 to 3 weeks dead!
BUT even a disconnected the battery will loose power, I do this all the time disconnect, 8 ALFA's. I hook up a battery charger an hour before I plan to drive the car of the day.
This is a good cause even though your battery can turn over the motor the starter is stressing cause of the low voltage from the battery most of the time. Know my Stuff!
A starter is a lot harder to change than a battery! If your car sits take my advise.
20/50 oil is thick!
Get a Tender, or follow my procedure.

"BUT even a disconnected the battery will loose (sic) power, I do this all the time disconnect, 8 ALFA's. I hook up a battery charger an hour before I plan to drive the car of the day"

I doubt you are hurting the starter because of a low battery, but yes, 20/50 can be thicker in Vermont winters, which can then be worse for the starter, and can cause a battery to go lower in it's stored energy level. A tender can reduce that problem for sure. In our mild winters, we generally don't have that problem of low energy levels in cold batteries. I can go for several months at least in the winter leaving the LS battery untouched if the car sits with the radio fuse removed.

I guess back to my original question...why remove the radio fuse when you can just have a battery terminal union disconnect? Seems easier to twist that than the fish a fuse out of the fuse box. Does it mess with the ARC to do that?

Though when disconnecting the battery, the clock need to be reset, etc.

No, a battery disconnect won't affect the ARC.

"Though when disconnecting the battery, the clock need to be reset, etc" and of course the radio memories, as you would with pulling that fuse. In the 164s, in which we do this, the battery cover in the trunk makes it just a little more of a pain to get to the battery cables where one would install a cutoff switch most likely, whereas the radio fuse is very easily accessed. Of course, if you don't want the car stolen, a cutoff switch in the trunk hidden behind the cover somehow would help with that.

For the Milano, at least the battery is right there in plain sight, lol. Easy to install a cutoff switch if that's your choice. For having a Milano stolen, they would never find the hood release pull. Took me a while to find it in ours, almost invisible.

Well, gonna get the multi-meter back out and try and find the leak again. If all else fails, a terminal cutoff it will be.

Thanks all!

On my Milano the courtesy lights came on randomly killing the battery.
I only figured it out after some late night insomnia, I saw the lights on in the driveway. I switched a bunch of relays but never did figure it out. I ended up just leaving the lights in the off position and turning them on when needed.

I have a screw-post-style disconnect on my Verde's battery and my ARC is still just as wacky as it was before, so I don't think it effects anything. I'm not sure if I even need one on there, but there are periods where the car doesn't get used for a few weeks at a time and I hate coming out to a dead battery. It also does make a nice security feature -- I'm willing to bet a thief isn't going to diagnose a no-start if he's trying to steal my car.
