Battery drain

My 1990 HR drains batteries which from what I read is not uncommon.
I have 3, 12 volt batteries wired parallel, batteries are less than a year old.
There are so many fuses in many locations so instead of trying to track down the drain I put a cut off switch on the positive lead that ties directly in to the coach wiring. This brings up my question.
*** Seems I am still getting battery drain even with positive lead disconnected.*** I thought with either lead disconnected it would eliminate battery drain. Should I have the disconnect on the ground???
Thanks, Jerry

Sounds like you might have a bad cell in one or more of the batteries. Batteries in uneven condition or capacity connected in parallel can self drain the entire pack. This can happen even with new batteries when one battery will hold a slightly less charge than the rest. Try disconnecting the batteries from each other and see if one or more of the batteries have an internal drain. Also check if the output voltage of each of the batteries both fully charged and under a load.

As the batteries are one a year old, a bad battery should still be under warranty.

The best way to avoid this situation is to install a battery isolator.

Jerry,

This is just one of the problems with lead acid batteries in parallel.

With what you are describing, I would suggest that undo all the paralleling and keep an eye on each. You have already determined that it is not a load draining the bank, but it can easily be one of the jars.
