2018 F450 V10 Dump Truck

[Tomtint]

So I have the truck in the title. It's been my plow truck and general heavy tow vehicle, mulch vehicle etc. It has about 15K miles on it since new.. It goes out in the worst of the worst of the worst weather.. Its on its 4th.. Yes 4th set of manifolds, 2nd set of heads, 4th set of brakes, rotors, callipers , 2nd set of trans lines, 2nd set of power steering lines, second set of shocks..... You get the idea. .. Anyway ..A recent issue has been the battery not holding a charge.. Or not charging enough. It cranks over slow at first with a brand new battery. Also, when I have the Boss plow on and use the electric controls to lift and angle the blade.. If the radio and heat are on, The radio and heat shut off until i release the plow buttons. Im wondering if this is a bad ground ...maybe the battery ground to chassis ?

Sounds like the plow is energized when you crank the motor and may be energized while it’s sitting. That is draining your battery.

The plow is definitely energized while cranking, But not when the ignition is off.

Have you checked for a battery draw while truck is parked? I’m not sure what you’re trying to resolve, a parked truck battery draw, or the funky electrical gremlins while running (I think thats what would bother me)

I run my plows through the upfitter switches, so nothing goes to plow until I turn on the upfitter plow switch.

I have not checked for a draw, Im sure with the radio there is always a small one. My belief is that the battery is not charging while its running or that its not charging enough due to a bad ground somewhere.

Whats your voltage amps while running?

Truck does not have a gauge for that inside

Batteries good? (I’m just trying to eliminate the easiest things first)

It only has 1 battery and it was replaced today.. It had a slight hesitation/lag when cranking at first .. Like it was about to go click click click.. But did turn over and start.
