alarm/remote starter killing battery

I will just have to probe the module and the remote start for 12v because if I try to do the draw test, once I put the dmm inline I don't have enough power for the remote start to work. That would be the only way for me to test the draw after a remote start. Thanks for the suggestion.

Back to old school, inductive ammeter.

Do you let the car remote start and let it time out? One of my customer's car had the same issue. Actually thanks to his troubleshooting we noticed that his auto lights stayed on after remote start shut down. We had to pulse a wire during crank and it took care of the issue.

No I haven't let it time out. What does letting it timeout do? How did you find out the lights were staying on, was it visual or you tested the wires?

I finally figured it out. It seems that there was something wrong with my bypass module. I replaced it and now everything seems to be all well. Thanks for all the help!

This happened to me awhile back when I used the GWR (ground while running) wire for the bypass module as well as for a relay- WITHOUT diode isolating them--- the relay was holding in by "grounding" through the bypass module- drew 150 ma whenever not in use- and only after a remote start- Did you try to power more than one item with your GWR wire?Brcidd - Engineer That Does Remote Starter Installs on the side.
