My battery in my truck is draining over a three day period. Had battery replaced but same drain. So I performed a amperage test on the negative battery cable and narrowed the problem down to the Ignition +12 volt constant. The only thing connected to that is my viper 570xv security rs system. So I called the installer as its under warranty and they said nring it in and they will take a look.
So I wanted to see for myself if the wires were all properly routed and good connections. They used crimp but connectors and not sure if thats professional. Anyway I am wondering if there is anything I can do before bringing it in. I mean my knee panel is geting pretty beat up and I am particular about keeping my car in shape. So basically I want to be 100% sure that the rs is the problem before bringing it in.
Can I just unplug the module brain and the xk01 bypass and see if thatsgops the drain or could this be a wiring issue? I have double checked the wiring and nothing seems odd except for something I heard in another thread about connecting the 200ma connection on the rs to the orange wire disarm sense on the xk01.
So just wondering what you think and if there is anything I can do. Looking for pointers on narrowing the drain down.
Also, want you guys.gals to know I have installed 160xv and 560xv before myself and never had issues with battery drain. And in case you are wondering the on the battery is approximately .01 volts per each hour. So in three days the battery with end up below 12 volts usually. Thanks!

The first question is, was it this way since you had it installed? A "wiring issue" doesn't change itself, so unless it was just installed wiring isn't the issue. The drain would have been from day one. It could be a product issue tho.

Try and perform the test correctly. If you are doing an amperage test you need to test the amperage draw, not voltage. Put your meter on 200ma and disconnect the battery terminal. Place the terminals on the post and the terminal, then wait for the BCM to fall asleep. You can check the time this takes ahead of time by leaving a door open and time the the interior lights going out, or just wait 20 minutes. If you end up with around 10ma or less your fine.

Man. Thats difficult to answer. I think this problem has been with me since day one because my battery died once in july and in october before realizing whats going on.

Yep just trying to rule out anything not related to the viper

Already did this at the beginning to find the correct fuse.

I did another amp draw test. With the IGN1 fuse installed I read 40ma draw after letting it sit for a while. Say 5 minutes. With IGN1 fuse removed I read less than 10ma. So my guess is that the remote start is draining my battery. Would a 40ma draw drain a battery in a weeks time? I guess its time to pull the viper module and see if that makes a difference.

Unplug the Brain and see if the Drain goes away.

Is there an external (to the Viper) starter cut/anti-grind relay installed and does the relay coil have orange to one side and ignition NOT constant to the other side.
If it's constant 12 volts+ that's your problem.
If you do the draw test as Mike suggested, leave it connected but unplug the Viper module, then redo the test if no difference it isn't the Viper.

Oh just remembered. Before I took that measurement of 40ma I found that the installer had the pink and pink/white wires on the xk01 connected to the viper. No reason to do that at all. So I Cut and taped them. Wait and see now.

I vote for Howie's answer about using IGN or START instead of constant.

Ok. Good news. I found the cause of my battery drain. I narrowed it down to the remote start system the installer put in. What I did was disconnect the brain and let it sit. Still had drain. Battery would loose .30 volts in two days. I then disconnected the XK01 and the battery has been holding at 12.50 volts for the past 2 days.
So the XK01 is the problem. Now my question is this. Should I just button everything back up the way the installer had it and let them figure it out all over again or should I take it to the installer and tell them whats wrong and point out the part thats bad?
