Customer Question
My new batteries are...

My new batteries are being drained in about 12hrs.

Mechanic's Assistant: Have you tested the battery with a voltmeter? And can you see if it's leaking or not?

They read 3vdc under load, when I removed them they read 10v. They are brand new Interstate marine 27's.

Mechanic's Assistant: What is the model/year of your RV?

92' 27 Terry

Mechanic's Assistant: Are you fixing your RV yourself? What have you tried so far?

Yes

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I noticed when I connected the batteries out in the woods I connected the positive first, because of location of connection, then connected the ground I got a lot of arcing in the negative terminal. I know in older cars this would indicate a draw on the battery.
