With the battery removed, I put the olm meter + &- terminals and got 27olms, is something wrong there?, thank you

 

There is no way of knowing. That is not a good way to test for a drain.

The simplest way is to hook a testlight in series with the negative battery cable like the diagram below. If the testlight lights up, you have a drain or a short circuit somewhere. If it doesn't light up your good.

You can also use a digital meter. Move the leads around on the meter to read amps, and hook it inline just like the testlight. Set it to read DC amps. You should get 70ma or less, which is .07 amps or less. Any more than this and the battery can run down if it sits for a couple of days.

 

Thank you for the response, I will give that a try, sorry about the qoute, I messed up & ca't undue it, thanks again

 

This is a nice video---even if a bit chatty---about parasitic current draws, how to find them:
