Diesail Posted December 30, 2011 Share Posted December 30, 2011 This makes a lot of sense. Thanks! I would have thought the dealer would have powerted the plow from the Aux battery. Do you think I should change the plow power leads to the aux battery? Moving the plow to the aux battery won't make any difference. The plow is used with the truck running and is power by the alternator with the batteries only jumping in to handle the sudden surges the plow needs. I just looked in my 08 FSM and see the primary is indeed the passerger side. Can someone, Diesail maybe, set me strait about my 2000 being the opposite? Mark I believe the primary switched from the front, drivers side to the rear, passengers side with the GMT900 trucks. My '05 has the primary on the driver's side. DEWFPO ding, ding, ding. Yep, 07.5 and up GMT900s. Link to comment Share on other sites More sharing options...
robertbick Posted December 30, 2011 Author Share Posted December 30, 2011 Thanks for everyones help! Do you think it is a good idea to switch the batts around? Kinda like giving the primary battery a break and putting the aux one into service for a while? Link to comment Share on other sites More sharing options...
RockySierra Posted December 30, 2011 Share Posted December 30, 2011 regardless of use, life expectancy for most batteries is 4-6 years, depending upon climate. Yes yes yes, there are some who have gone way up to 10+ years and of course that is the exception to the rule, but in general, 4-6 years. I'm not sure there would be any advantage to swapping the batteries around at this point, or even at all. Link to comment Share on other sites More sharing options...
robertbick Posted December 31, 2011 Author Share Posted December 31, 2011 Well, I just got my BatteryMinder from Amazon.com today so hooked it up to the weak primary battery and will keep it charged when I'm not using the truck. Link to comment Share on other sites More sharing options...
