I have hooked up a deep cycle battery to my sprayer trailer to run the electric reel. The battery is hooked to the electric reel motor through a switched relay.

The problem is that my main truck battery has been draining everynight since i have installed the extra battery. However, my rudimentry, but I beleive sound, understanding of 12v electrics doesn't support this. There is no reason for the trailer battery to drain the truck battery -- that I can see.

Even if my trailer and truck are sharing a ground through the hitch -- it still should not drain my truck battery right?

But... what if the relay or the motor on the trailer are drawing a small current? COuld that cause a drain on my main truck battery -- I don't think so -- but maybe?

Any thoughts?

Sounds like you have two seperate problems. I would have truck checked out.

I haven't got it figured out yet.

I have jusy been unhooking the ground to the sprayer battery and have had no problems. Right now in the middle of seeding time -- I don't ahve an extra few hours to diagnose it.

It's got me baffled.
