M1272 Buffalo: The Pain of Battery Drain


This article initially appeared in PS 775 (Jun 17), p. 15.

It’s no secret that electronics inside the M1272 Buffalo have a bad habit of running the vehicle’s batteries dry. And those batteries can lose their charge in just a week!
        
No juice means a slave start or you’ll be going nowhere at all.  So, after the day’s run, use the two battery disconnect switches to protect those batteries.

You’ll find the first switch under the hood on the driver’s side of the vehicle. The second switch is inside the vehicle under the passenger seat.
        
While you’re at it, make sure the #1 and #2 power distribution module (PDM) switches are turned to the OFF position. That turns off all power to commo gear.   
           
You’ll find the PDM switches inside the back of the Buffalo.
