Hey how’s it going, I am new! Anyways my plow just last night started to kill my truck when I move it, I thought it was the alternator but it is charging at 14.6 volts, the battery is pretty old and I don’t even know what it is. The plow and truck work fine unless I lift it up and set it down like 5-6 times then it kills the truck. I had a load test done on the alt and it was perfectly fine. I have a 2004 F-250 with the 6.8L V-10

A short, And your solenoid could be shorting out.
does it smell burnt that electrical burning smell?

Follow the power leads out to the plow.
do they look good or have they rubbed through someplace?

Open the cover sniff around the coils anything smelt burnt?

Doesn’t take much though to kill a battery with a bad cell , have you had the battery tested?

I once had a hoist on an old truck that periodically killed my engine. It turned out the engine ground was bad and it was grounding through the solenoid for the hoist. When I applied power to the hoist it killed the engine.
Replacing the engine ground fixed it.

But yeah if your battery is bad... Start there.

Like others have said check your grounds.

Had a Bronco break the ground from the engine block up to the battery. Broke at the clamp on the frame. LOOKED fine but after 3 months of chasing gremlins I finally noticed it. Went to unbolt the end to clean it and the ground wire fell off.
