Pull all the fuses keep the customers car overnight test the voltage before disconnecting and then check in the morning. Also you could also test for any current draw with the fuses in and with the fuses out of the remote starter. You should have very minimal current draw it should be under 1 amp

Battery draw on MOST vehicles should be about 25-30 milliamps stock, I find an extra 10milliamps draw from a remote starter with a module to be common...should you should be seeing 40mA max. If there is anymore than that, something is wrong. The easiest way to see if its the remote starter, is to keep the vehicle over nite with the fuses out of your system. If the batterys still good in the morning you know your starter is more than likely the culprit

thanks for the reply's,but how do you do a curent draw test(I know installer that does'nt know}LOL

Oh yea, normal draw on this is 50mil,and dealer says now 200mil so if I could test and unplug seperate plugs Id know where to look.

you need to put diodes on the dorr locks relays from the module. wihtout it drains the battery- computer wont go to sleep.

cmk is right. It has something to do with the commputer sending out test pulses or something to that nature. Anyways, if you dont use the diodes, the computer will stay awake, which causes the battery to drain.
On a side note, I am also wondering what the best method is to test battery drain. I know that you put the DMM between the positive side terminal, and the wire (in-line) but what setting do you use on the DMM, and will most DMM's work?

your dmm has to have an amperage setting. usually it will have its own plug and will either be fused or not fused. you set the meter to dc amps and connect one test lead to battery, other to the disconnected battery terminal. and check the amperage draw with the doors closed, lights off, etc...measure the current draw right as you hook it up and then wait like half an hour for everything to go to sleep. if your meter has a peak hold setting you can use that to record the highest draw, you can use that to see if the computer is sending pulses and not going to sleep. it will spike when it gets a pulse so you set peak hold at a baseline reading where you think the computer is alseep. if the computer sends a pulse then you will notice the draw being higher than what you recorded previously. super cheap dmm's wont have a current draw feature but a majority of dmm's $20 and up will. ------------- git yer swerve on!

You guy's rock,everything works great and that was the problem.It was pulling an extra 175Ma and radar detector was pulling 200 and their phonecharger with a phone connected was a extra 400 so all in all fixed and thankyou.oh yeah stock is 29 spikes to 50 about every 40 sec.

A true ignition off draw requires putting your multimeter in series with the negative battery cable of the battery
