drain on battery

I have a drain on my battery. if i disconnect the negative terminal on the battery i can hear a relay click in the fuse box right by the battery. I have located the relay and if i look at the diagram on the fuse box lid it says its my cooling fan relay??? i don't have an electric fan.

i believe the blank far right one. i took out the one just to the left of it and it didn't turn over so that had to be the starter. so that has to be the one.

That makes it easy. So the yellow write from the ignition switch must be on. Disconnect the ignition switch connector and see if the relay still stays on.

It doent make sense because the supply voltage side is always hot to the starter. If the relay was pulling in the starter would be trying to start all the time. Do you have a meter?

Look at the relay with the key off. You have 5 terminals. Ignore the middle one. On the outside of the relay you will see a diagram with 30, 85, 86 and 87. With your meter refrensed to battery ground measure the voltage on 85 and 86 of the relay that you pulled.

What does this relay activate exactly?. If I have power asking the relay to close with the key of something is messing up?
