i think my viper rs is draining my battery

This recommendation is to limit feedback and noise induction to the vehicle's components mainly but it also goes the other way too. Where the an ECU may cause undesirable effects to the aftermarket product that is installed.This information is provided only as a reference.

All circuits should be verified with a digital multi-meter prior to making any connections.

Thanks.

Ralph, not familiar with that unit but as a plain by-pass it should draw nothing at rest. As a data conversion unit it still seems too much to me. As an example most GPS trackers draw under 1mA.

The strange thing about all of this is if I remove the ignition fuse which the remote start and bypass use power from then the battery doesnt die in three days. The rs and bypass are only using 30mA which shouldnt drain the battery. I can actually watch the volts go down .01 in one hours time. I wonder if because its below 32 degrees something is getting activated like the rear defrost or something. If I take this in they are going to say there is no problem.2005 GMC Envoy XL

Rear defrost should only activate after R/S is engaged.

Im wondering if the battery is toast. I set off the alarm yesterday with the headlights on for about 10 seconds with the siren blaring. I saw the battery voltage dropped to 11.75. I kept the meter on the battery and it took 20 minutes for the voltage to come back up to 12.52005 GMC Envoy XL

Yeah, thats my understanding as well. Apparently something is engaged if its using so much power. I am going to get a new battery to see if it is a reserve capacity issue. Yesterday I charged the battery when it was at 12.3 volts and it only took 5 minutes to charge up to 12.6 which seems very short at a 10 amp charge rate.2005 GMC Envoy XL

I left this line out of my last post because I was sure you said earlier that you changed your battery but I might have been wrong. Have your battery thoroughly tested.

I did replace the battery a few months ago but was still experiencing the same drain problem. So I returned the battery and using the original again. I kept it and didn't return as a core.2005 GMC Envoy XL

So I brought it into the shop today and the first thing they did was pull the ignition fuse and took a amp reading. 30mA. They said that is nothing and not the cause of the drain. They also said 8 times out of 10 its the battery. So I guess I am back to square one. Thats weird because the when I disconnect the remote start and bypass thebattery never drains. Why or how can a 30mA draw kill a battery in 3 to 4 days is beyond me. It should last 2 or 3 weeks. Right?2005 GMC Envoy XL
