Question on Chevy Factory Dual Battery Setup

    I have an 06' 2500HD with 6.0L with the factory dual battery setup. The batteries both are less than a year old. I have strobes in each corner of the truck that I turn on when I mow. I was chatting with a customer longer than usual 2 hours or so and the battery went dead. I have read up on the system since and kind of understand the isolation setup between the 2 batteries. My question is would the secondary battery take the voltage from the strobes if I left the key on (with the truck off). Leaving the main fully charged for starting the truck. Thanx for any help

    Who cares? Just turn the strobes off!

    You're about as helpful as tits on a wheelbarrow. The strobes are on for safety while my truck and trailer are parked on the road.

    Those are the wrong color cones for parking on the side of the road! Those are for warning of a pedestrian hazard.

    Hmmmm, I didn't know my truck and trailer were in danger. I guess all cars should be doing this then when they are parking on the road all day every day?

    If your Chevy is set up like my Dodge, it doesn't matter which battery you connect too because they are still connected to each other.

    Thanks for the OSHA lesson! Just an example!

    The point I was making is visibility.

    Lots of co. around here use lime cones.

    2 or 3 of these around the truck and trailer will provide the same result as orange cones.

    I also think the lime cones stand out more. Anyways a cone is a cone in my book. Many pages in my book!!

    It sounds like its time for new batteries, they should be able to run a set of strobes like that.

    There is a universal color code for traffic signal devices. The lime cones should be used when there is a pedestrian hazard, like a crosswalk or something. To warm of a vehicle parked in a traffic lane, orange cones should be used.

    I know that in a lot of dual battery systems there is a relay that joins them once the vehicle starts and seperates them when it is shut off, but that's for coach batteries in campers and stuff. You should be able to figure it out with a voltmeter.

    I for one understand why you would want to keep your strobes on while parked. I turn my hazards on sometimes if I'm parked on a busy road. If i'm going to be there for an extended period I fire the truck up once an hour or so.
