5902, xk01, dead 2006 envoy battery

Because the original question hasn't been answered by you. Did they use an orange directly to the relay? Also as Oldspark correctly pointed out the relay was technically wired wrong in the first place. I don't often make mistakes from knowledge, if I do I'm the first to apologise, secondly as Oldspark and others here know I'm probably one of the best diagnostic technicians around. So if I think I'm wasting my time, and yes once you or any other rookie starts spouting off how good they are then yes we're getting a bit snarky.

Understandable and thank you for the explanation.  I stated the experience not to show off, but to provide some level of compentence of skill to follow instructions, perform diagnostics and ability to use a meter and scope.  I too have been on many boards where it is difficult to help others unless you know what level of skill set they are at.  That was my ONLY intent.  Sorry if I offended you and others, it was certainly not to show off.  The Viper has 2 Orange wires..The first on the main harness H1/12  which is GWA, this wire and this wire is not connected.  The second is H2/12 which is (-) 200ma Accessory Output and this is the wire connecting to the relay.  I believe the installer is using this to supply the 2nd acc line (Brown Envoy Harness) with power for remote start.  This is based on others posting on this thread.  Thank You.

OK, that's fine now you just have to make sure H2/12 doesn't sit on ground all the time.

Thank you.  I get to it first thing on Monday when I reinstall the system and start testing.

I confirmed the relay is used for remote start.  Provides power to the ACC 2 wire as required for remote start.  Relay is not stuck or always active.

Now off to connecting a amp meter and wait and watch for voltage spikes.

Don't think there will be spikes but a constant drain on the battery, say half an amp as against 40-80 milliamps . It's then down to the rotten task of removing one fuse at a time including the alarm-R/S till you find it.

I agree.  I was told once that this kind of job requires a tapper and a keg of the midwests finest and lots of time.  Thanks for your help.

I was having the same issue in my 05 Suburban. I know you had your module replaced but my problem was my XK01. It was programmed because the locks and rs were working fine but when I opened her up to start looking for draws I noticed the led in the module was on constant. I unplugged it, re-programmed the module and haven't had issues since. I think it was sending constant signal to the alarm brain and not allowing it to sleep. I'm down to about 28mA now.

Thanks
