M35A3 with electrical draw

[hot rod deuce]

Hey guys,

Ive been knocking myself out, I have an M35 A3 with a draw that kills one battery. Is this a common problem with a common fix?

Add a disconnect. Best way to avoid this.

Maybe that battery is suspect. If you had an un-welcome current draw, seems to me both batteries would be affected. Maybe time to invest in a couple of batteries, don't just replace one. As rmgill said a disconnect is always a good idea.

I have 2 a3s and both have new battreys and if they sit a long time the back battrey on both trucks will go down.
