    I would just go look at a Diesel and buy the factory stuff from one of those from a junk yard... we did the same thing on a Chevy a few years back and it worked perfectly!

    I'm not sure the "diesel parts" think will work. The diesel battery box is built in with the air intake, which is different than the gassers. You might be able to use it, but would have to cut the box apart.

    If I recall, doesn't the gas system have the EVAP control filter in that spot?

    good idea there too.

    Thanks
     
  12. I haven't had any issues with my single battery in my F250 in the past few years of plowing but I've wondered about adding one just in case. When putting dual batteries in your trucks, are they wired in parallel or are they connected via a switch (manual or voltage sensing)?

    Is that using the original factory single battery tray? What size/model Optima battery are you using there?

    If not what tray is it, and where did you get it?

    BTW, what year and model etc is the truck?

    When you have 2 batteries, do they have to be connected to one another? Can you have the original battery as is and the second battery (connected to alternator & ground) wired to plow/lights/salters/extra stuff?

    They should be connected by at least a 4 guage wire.

    When one of the batteries draws a heavy load (like the plow or the starter) the other will try to compensate. In your example, that would be through the alternator wire, which could be too small, overheat and melt.

    This is unless you had one set up as an auxillary battery through an isolator. Then the second would not compensate. If the second battery can't compensate, there's no reason to have two. Those setups are for RV's and things where you have a load when the alternator isn't charging and you don't want to drain your start battery.

    How would you wire up 2 batteries in the same location? Like 2 optimas. I just bought 1 and it doesnt have near the power i was hoping. Its a v10 btw

    From what I have read on P.S. you should have 2 of basically the same age. If you are going to buy one, buy 2 and then the new one won't have to do all the work.

    A quick correction would be 2 gauge, but 0 or 00 guage is better. on diesels the factory wiring for the positive cable is a two gauge.
