having battery drain issues

well what you need to do is get a multi meter as suggested with an amp setting on it .set it to ma and connect one probe to the pos. terminal of battery and the other to the pos. cable that goes to the battery. make sure nothing is on in the car the doors are shut and nothing like the hood light is on, when you do this (it could damage the meter)and will not let you get a proper reading. you will have some draw on the battery because of the computer and some door lock modules. but anything over 2 miili amps of draw is going to kill the battery.

so you take the reading and you start the trail and error part, you will need to start at the fuses and suspected curcuits that may be the problem by disconnecting them and any relays. one by one taking a reading after everyone and when taking the reading make sure everything is off, doors shut , hood lamp off everything ever time. a helper will come in handy in this job. when the high reading drops you have found a draw and if it dont go all the way down to the aloud draw of the car, then you have more than one and the search goes on.

it all time and patience good luck. let us know what happens

Sounds like you may have the relays wired in reverse, using the normally open contacts as the default position.

If you do that, the relay coils are energized and will draw a fair amount of power; if you have a bunch of them wired up this way, that can cause your excessive battery drain problem.

If the relays click when you connect and disconnect the line that you tapped off from to power the relays, while the car is off and in standby mode, that's an indication you're using them backwards.  Since you said they click when you connect power to them, I'd guess that's what the problem is.

You may need to redo the wiring setup for the relays if that's the case-

i just reread and didn't understand the first time. dual sport is right and you should start there (SUSPECTED CURCUITS)with the advise i gave you.

hey dual sport i lost track of that other topic did he ever get back on that issue. did he get a new unit?thankx for pointing that out also you probly save him some time.

If the drain is able to take down an Optima battery in just two days, you can just use a small test light to check for the current drain-

Connect one side of the test light to the battery terminal, and the other side to the battery post, then disconnect the terminal from the post, so the light is now in series with the battery.

With the kind of drain you're probably having, the light will glow visibly- at that point, start disconnecting things as fingaz suggested, and continue until the light goes out-

I'd start by just unplugging all the relays from the sockets, since that'll remove the draw from both the relay coil and the things you're controlling with them.

fingazz, haven't heard yet if he's got a new unit yet;  hopefully he finds something reliable!

ya i always like doing it right the first time myself. it just saves time and money in the long run evrytime.

keep it wired. later

there are  all but the doorlocks courtesy of webshots..

also, what setting do i use on this multimeter...im assuming it will be under "DC A" for amps....here are the options i have

thanks for all the help so far!!
