The reason I’m asking is I put a charger on my truck this morning and smoke was coming from the terminals instantly and there was like a surge sound coming from the motor not running

Are you 100% positive that the charger cables were attached correctly?, the charger voltage was set correctly? The charger is operating correctly and you have verified the output of the charger?

 

[mkcustoms881]

Yes when I hooked up the positive it arc small black marks on the post , truck has been sitting few months

Battery is toast. Get a new one. There's several grounds on the engine to cab and engine to chassis.
1. Battery - to the block
2. Block - to the cab firewall (flat wire rope looking ground wire)
Mainly for radio noise reduction.
3. The pos+ cable goes to the starter there should be a couple other power wires that go to the fuse box

OP I'm curious as if you might have connected the charger backwards. Its possible...
